Tapes Evolving Role

Sure we have heard for decade’s about the death of tape, and someday it will be dead and buried (I mean really dead), no longer used, buried, existing only in museums. Granted tape has been on the decline for some time, and even with many vendors exiting the marketplace, there remains continued development and demand within various data infrastructure environments, including software defined as well as legacy.

data infrastructures

Tape remains viable for some environments as part of an overall memory data storage hierarchy including as a portability (transportable) as well as bulk storage medium.

memory data storage hirearchy classes tiers

Keep in mind that tapes role as a data storage medium also continues to change as does its location. The following table (via Software Defined Data Infrastructure Essentials (CRC Press)) Chapter 10 shows examples of various data movements from source to destination. These movements include migration, replication, clones, mirroring, and backup, copies, among others. The source device can be a block LUN, volume, partition, physical or virtual drive, HDD or SSD, as well as a file system, object, or blob container or bucket. An example of the modes in Table 10.1 include D2D backup from local to local (or remote) disk (HDD or SSD) storage or D2D2D copy from local to local storage, then to the remote.

Mode – Description
D2D – Data gets copied (moved, migrated, replicated, cloned, backed up) from source storage (HDD or SSD) to another device or disk (HDD or SSD)-based device
D2C – Data gets copied from a source device to a cloud device.
D2T – Data gets copied from a source device to a tape device (drive or library).
D2D2D – Data gets copied from a source device to another device, and then to another device.
D2D2T – Data gets copied from a source device to another device, then to tape.
D2D2C   Data gets copied from a source device to another device, then to cloud.
Data Movement Modes from Source to Destination

Note that movement from source to the target can be a copy, rsync, backup, replicate, snapshot, clone, robocopy among many other actions. Also, note that in the earlier examples there are occurrences of tape existing in clouds (e.g. its place) and use changing.  Tip – In the past, “disk” usually referred to HDD. Today, however, it can also mean SSD. Think of D2D as not being just HDD to HDD, as it can also be SSD to SSD, Flash to Flash (F2F), or S2S among many other variations if you prefer (or needed).

For those still interested in tape, check out the Active Archive Alliance recent posts (here), as well as the 2017 Tape Storage Council Memo and State of their industry report (here). While lower end-tape such as LTO (which is not exactly the low-end it was a decade or so ago) continues to evolve, things may not be as persistent for tape at the high-end. With Oracle (via its Sun/StorageTek acquisition) exiting the high-end (e.g. Mainframe focused) tape business, that leaves mainly IBM as a technology provider.

With a single tape device (e.g. drive) vendor at the high-end, that could be the signal for many organizations that it is time to finally either move from tape or at least to LTO (linear tape open) as a stepping stone (e.g. phased migration). The reason not being technical rather business in that many organizations need to have a secondary or competitive offering or go through an exception process.

On the other hand, just as many exited the IBM mainframe server market (e.g. Fujitsu/Amdahl, HDS, NEC), big blue (e.g. IBM) continues to innovate and drive both revenue and margin from those platforms (hardware, software, and services). This leads me to believe that IBM will do what it can to keep its high-end tape customers supported while also providing alternative options.

What This All Means

I would not schedule the last tape funeral just yet, granted there will continue to be periodic wakes and send off over the coming decade. Tape remains for some environments a viable data storage option when used in new ways, as well as new locations complementing flash SSD and other persistent memories aka storage class memories along with HDD.

Personally, I have been directly tape free for over 14 years. Granted, I have data in some clouds and object storage that may exist on a very cold data storage tier possibly maybe on tape that is transparent to my use. However just because I do not physically have tape, does not mean I do not see the need why others still have to or prefer to use it for different needs.

Also, keep in mind that tape continues to be used as an economic data transport for bulk movement of data for some environments. Meanwhile for those who only want, need or wish tape to finally go away, close your eyes, click your heels together and repeat your favorite tape is not alive chant three (or more) times. Keep in mind that HDDs are keeping tape alive by off loading some functions, while SSDs are keeping HDDs alive handling tasks formerly done by spinning media. Meanwhile, tape can and is still called upon by some organizations to protect or enable bulk recovery for SSD and HDDs even in cloud environments, granted in new different ways.

What this all means is that as a zombie technology having been declared dead for decades yet still live there is life after death for tape, which is still alive, for now.

Ok, nuff said (for now…).

Tape talk time (tape summit and tape is alive, for some)

Welcome to the tape summit resources and tape summit resources micro site with links for those who are interested in magnetic tape for backup, archive, BC, DR, big and little data

For being a declared dead or zombie technology (here, here or here) tape remains very much alive however its role is changing. There is no disputing that hard disk drives (HDDs) are continuing to expand their role for data protection including backup/restore, BC and DR where tape has been used  for decades.

What is also occurring is that tapes role is changing from day to day backup to that of longer term data preservation including archiving with more data stored on tape today than in past history at a lower cost. In fact the continued reduced cost per tape and improved capacity as well as utilization has worked against tape from a marketing competitive standpoint. For example if you look at a chart showing tape (media and drive) revenues you see a decline, similar to what was seen a couple of years ago for HDDs.

What is not shown on some charts are how many units (drives or media) shipped with more capacity for a given price (again what was reported for HDDs a few years ago) when net capacity had increased. Vendors of tape technology have also had a rather low profile particular for those with other technologies that have received more marketing resources (people, time, money). After all, if a product is on a plateau of productivity and profitability why spend time or effort on extensive marketing or promotion vs. directing resources to get new items into the market.

As a result, for those looking to make a case that tape is on the decline based on revenues to convince customers to move away from that technology should have a marketing freebie. Recently Oracle announced a new large capacity tape drive and media following on previous announcements of enhanced LTO roadmap and future 35TByte  tape capabilities announced January 2010 by Fujifilm and IBM.

For those who are interested following are some links to various topics including how SSD, HDD and tape can coexist complementing each other for different roles or functions. As to those who do not like tape, feel free to read if you like as there is also material on SSD, HDD, dedupe, cloud, data protection and other topics.

Some previous blog posts:

Here are some additional articles, commentary and reports pertaining to tape related topics:

Something tells me we will be hearing, reading or watching more about tape being alive in the months to come.

Nuff said for now

Have VTLs or VxLs become Zombies, Declared dead yet still alive?

Have you heard or read the reports and speculation that VTLs (Virtual Tape Libraries) are dead?

It seems that in IT the all to popular trend is to declare something dead so that your new product or technology can have a chance of making it in to the market or perhaps seen in a better light.

Sometimes this approach works to temporary freeze the market until common sense and clarity returns to the market or until something else fun to talk about comes along and in other cases, the messages can fall on deft ears.

The approach of declaring something dead tends to play well for those who like shiny new toys (SNT) or new shiny toys (NST) and being on the popular, cool trendy bandwagon.

Not surprisingly, while some actual IT customers can fall into the SNT or NST syndrome, its often the broader industry including media, bloggers, analysts, consultants and other self proclaimed or anointed pundits as well as vendors who latch on to the declare it dead movement. After all, who wants to talk about something that is old, boring and already being sold to paying customers who are using it. Now this is not a bad thing as we need a balance of up and coming challengers to keep the status quo challenged, likewise we need a balance of the new to avoid death grips on the old and what is working.

Likewise, many IT customers particularly larger ones tend to be very risk averse and conservative with their budgets protecting their investments thus they may only go leading bleeding edge if there is a dual redundant blood bank with a backup on hot standby (thats some HA humor BTW).

Another reason that declaring items dead in support of SNT and NST is that while many of the commonly declared dead items are on the proverbial plateau of productivity for IT customers, that also can mean that they are on the plateau of profitability for the vendors.

However, not all good things last and at sometime, there is the need to transition from the old to the new and this is where things like virtualization including virtual tape libraries or virtual disk libraries or virtual storage library or what ever you want to call a VxL (more on what a VxL is in a moment) can come into play.

I realize that for some, particularly those who like to grasp on to SNT, NST and ride the dead pool bandwagons this will probably appear as snarky or cynical which is fine, after all, for some, you should be laughing to the bank and if not, you may in fact be missing out on an opportunity for playing in the dead pool marketing game.

Now back to VxL.

In the case of VTLs, for some it is the T word that bothers them, you know T as in Tape which is not a SNT or NST in an age where SSD has supposedly killed the disk drive which allegedly terminated tape (yeah right). Sure tape is not being used as much for backup as it has in the past with its role shifting to that of longer term retention, something that it is well suited for.

For tape fans (or cynics) you can read more here, here and here. However there is still a large amount of backup/restore along with other data protection or preservation (e.g. archiving) processing (software tools, processes, procedures, skill sets, management tools) that still expects to see tape.

Hence this is where VTLs or VxLs come into play leveraging virtualization in an Life Beyond Consolidation (and here) scenario providing abstraction, transparency, agility and emulation and IMHO are still very much alive and evolving.

Ok, for those who do not like or believe in or of its continued existence and evolving role, substitute the T (tape) with X and you get a VxL. That is, plug in what ever X word that makes you happy or marketable or a Shiny New TLA. For example Virtual Disk Library, Virtual Storage Library, Virtual Backup Library, Virtual Compression Library, Virtual Dedupe Library, Virtual ILM Library, Virtual Archive Library, Virtual Cloud Library and so forth. Granted some VxLs only emulate tape and hence are VTLs while others support NAS and other protocols (or personalities) not to mention functionality ranging from replication, DFR as well as automated policy management.

However, keep in mind that if your preference is VTL, VxL or what ever other buzzword bingo name that you want to use or come up with, look at how virtualization in the form of abstraction, transparency and emulation can bridge the gap between the new (disk based data protection) combined with DFR (Data Footprint Reduction) and the old (existing backup/restore, archive or other management tools and processes.

Here are some additional links pertaining to VTLs (excuse me, VxLs):

  • Virtual tape libraries: Old backup technology holdover or gateway to the future?
  • Not to mention here, here, here, here or here.

2010 and 2011 Trends, Perspectives and Predictions: More of the same?

2011 is not a typo, I figured that since Im getting caught up on some things, why not get a jump as well.

Since 2009 went by so fast, and that Im finally getting around to doing an obligatory 2010 predictions post, lets take a look at both 2010 and 2011.

Actually Im getting around to doing a post here having already done interviews and articles for others soon to be released.

Based on prior trends and looking at forecasts, a simple predictions is that some of the items for 2010 will apply for 2011 as well given some of this years items may have been predicted by some in 2008, 2007, 2006, 2005 or, well ok, you get the picture. :)

Predictions are fun and funny in that for some, they are taken very seriously, while for others, at best they are taken with a grain of salt depending on where you sit. This applies both for the reader as well as who is making the predictions along with various motives or incentives.

Some are serious, some not so much…

For some, predictions are a great way of touting or promoting favorite wares (hard, soft or services) or getting yet another plug (YAP is a TLA BTW) in to meet coverage or exposure quota.

Meanwhile for others, predictions are a chance to brush up on new terms for the upcoming season of buzzword bingo games (did you pick up on YAP).

In honor of the Vancouver winter games, Im expecting some cool Olympic sized buzzword bingo games with a new slippery fast one being federation. Some buzzwords will take a break in 2010 as well as 2011 having been worked pretty hard the past few years, while others that have been on break, will reappear well rested, rejuvenated, and ready for duty.

Lets also clarify something regarding predictions and this is that they can be from at least two different perspectives. One view is that from a trend of what will be talked about or discussed in the industry. The other is in terms of what will actually be bought, deployed and used.

What can be confusing is sometimes the two perspectives are intermixed or assumed to be one and the same and for 2010 I see that trend continuing. In other words, there is adoption in terms of customers asking and investigating technologies vs. deployment where they are buying, installing and using those technologies in primary situations.

It is safe to say that there is still no such thing as an information, data or processing recession. Ok, surprise surprise; my dogs could have probably made that prediction during a nap. However what this means is more data will need to be moved, processed and stored for longer periods of time and at a lower cost without degrading performance or availability.

This means, denser technologies that enable a lower per unit cost of service without negatively impacting performance, availability, capacity or energy efficiency will be needed. In other words, watch for an expanded virtualization discussion around life beyond consolidation for servers, storage, desktops and networks with a theme around productivity and virtualization for agility and management enablement.

Certainly there will be continued merger and acquisitions on both a small as well as large scale ranging from liquidation sales or bargain hunting, to large and a mega block buster or two. Im thinking in terms of outside of the box, the type that will have people wondering perhaps confused as to why such a deal would be done until the whole picture is reveled and thought out.

In other words, outside of perhaps IBM, HP, Oracle, Intel or Microsoft among a few others, no vendor is too large not to be acquired, merged with, or even involved in a reverse merger. Im also thinking in terms of vendors filling in niche areas as well as building out their larger portfolio and IT stacks for integrated solutions.

Ok, lets take a look at some easy ones, lay ups or slam dunks:

  • More cluster, cloud conversations and confusion (public vs. private, service vs. product vs. architecture)
  • More server, desktop, IO and storage consolidation (excuse me, server virtualization)
  • Data footprint impact reduction ranging from deletion to archive to compress to dedupe among others
  • SSD and in particular flash continues to evolve with more conversations around PCM
  • Growing awareness of social media as yet another tool for customer relations management (CRM)
  • Security, data loss/leap prevention, digital forensics, PCI (payment card industry) and compliance
  • Focus expands from gaming/digital surveillance /security and energy to healthcare
  • Fibre Channel over Ethernet (FCoE) mainstream in discussions with some initial deployments
  • Continued confusion of Green IT and carbon reduction vs. economic and productivity (Green Gap)
  • No such thing as an information, data or processing recession, granted budgets are strained
  • Server, Storage or Systems Resource Analysis (SRA) with event correlation
  • SRA tools that provide and enable automation along with situational awareness

The green gap of confusion will continue with carbon or environment centric stories and messages continue to second back stage while people realize the other dimension of green being productivity.

As previously mentioned, virtualization of servers and storage continues to be popular with an expanding focus from just consolidation to one around agility, flexibility and enabling production, high performance or for other systems that do not lend themselves to consolidation to be virtualized.

6GB SAS interfaces as well as more SAS disk drives continue to gain popularity. I have said in the past there was a long shot that 8GFC disk drives might appear. We might very well see those in higher end systems while SAS drives continue to pick up the high performance spinning disk role in mid range systems.

Granted some types of disk drives will give way over time to others, for example high performance 3.5” 15.5K Fibre Channel disks will give way to 2.5” 15.5K SAS boosting densities, energy efficiency while maintaining performance. SSD will help to offload hot spots as they have in the past enabling disks to be more effectively used in their applicable roles or tiers with a net result of enhanced optimization, productivity and economics all of which have environmental benefits (e.g. the other Green IT closing the Green Gap).

What I dont see occurring, or at least in 2010

  • An information or data recession requiring less server, storage, I/O networking or software resources
  • OSD (object based disk storage without a gateway) at least in the context of T10
  • Mainframes, magnetic tape, disk drives, PCs, or Windows going away (at least physically)
  • Cisco cracking top 3, no wait, top 5, no make that top 10 server vendor ranking
  • More respect for growing and diverse SOHO market space
  • iSCSI taking over for all I/O connectivity, however I do see iSCSI expand its footprint
  • FCoE and flash based SSD reaching tipping point in terms of actual customer deployments
  • Large increases in IT Budgets and subsequent wild spending rivaling the dot com era
  • Backup, security, data loss prevention (DLP), data availability or protection issues going away
  • Brett Favre and the Minnesota Vikings winning the super bowl

What will be predicted at end of 2010 for 2011 (some of these will be DejaVU)

  • Many items that were predicted this year, last year, the year before that and so on…
  • Dedupe moving into primary and online active storage, rekindling of dedupe debates
  • Demise of cloud in terms of hype and confusion being replaced by federation
  • Clustered, grid, bulk and other forms of scale out storage grow in adoption
  • Disk, Tape, RAID, Mainframe, Fibre Channel, PCs, Windows being declared dead (again)
  • 2011 will be the year of Holographic storage and T10 OSD (an annual prediction by some)
  • FCoE kicks into broad and mainstream deployment adoption reaching tipping point
  • 16Gb (16GFC) Fibre Channel gets more attention stirring FCoE vs. FC vs. iSCSI debates
  • 100GbE gets more attention along with 4G adoption in order to move more data
  • Demise of iSCSI at the hands of SAS at low end, FCoE at high end and NAS from all angles

Gaining ground in 2010 however not yet in full stride (at least from customer deployment)

  • On the connectivity front, iSCSI, 6Gb SAS, 8Gb Fibre Channel, FCoE and 100GbE
  • SSD/flash based storage everywhere, however continued expansion
  • Dedupe  everywhere including primary storage – its still far from its full potential
  • Public and private clouds along with pNFS as well as scale out or clustered storage
  • Policy based automated storage tiering and transparent data movement or migration
  • Microsoft HyperV and Oracle based server virtualization technologies
  • Open source based technologies along with heterogeneous encryption
  • Virtualization life beyond consolidation addressing agility, flexibility and ease of management
  • Desktop virtualization using Citrix, Microsoft and VMware along with Microsoft Windows 7

Buzzword bingo hot topics and themes (in no particular order) include:

  • 2009 and previous year carry over items including cloud, iSCSI, HyperV, Dedupe, open source
  • Federation takes over some of the work of cloud, virtualization, clusters and grids
  • E2E, End to End management preferably across different technologies
  • SAS, Serial Attached SCSI for server to storage systems and as disk to storage interface
  • SRA, E23, Event correlation and other situational awareness related IRM tools
  • Virtualization, Life beyond consolidation enabling agility, flexibility for desktop, server and storage
  • Green IT, Transitions from carbon focus to economic with efficiency enabling productivity
  • FCoE, Continues to evolve and mature with more deployments however still not at tipping point
  • SSD, Flash based mediums continue to evolve however tipping point is still over the horizon
  • IOV, I/O Virtualization for both virtual and non virtual servers
  • Other new or recycled buzzword bingo candidates include PCoIP, 4G,

RAID will again be pronounced as being dead no longer relevant yet being found in more diverse deployments from consumer to the enterprise. In other words, RAID may be boring and thus no longer relevant to talk about, yet it is being used everywhere and enhanced in evolutionary ways, perhaps for some even revolutionary.

Tape remains being declared dead (e.g. on the Zombie technology list) yet being enhanced, purchased and utilized at higher rates with more data stored than in past history. Instead of being killed off by the disk drive, tape is being kept around for both traditional uses as well as taking on new roles where it is best suited such as long term or bulk off-line storage of data in ultra dense and energy efficient not to mention economical manners.

What I am seeing and hearing is that customers using tape are able to reduce the number of drives or transports, yet due to leveraging disk buffers or caches including from VTL and dedupe devices, they are able to operate their devices at higher utilization, thus requiring fewer devices with more data stored on media than in the past.

Likewise, even though I have been a fan of SSD for about 20 years and am bullish on its continued adoption, I do not see SSD killing off the spinning disk drive anytime soon. Disk drives are helping tape take on this new role by being a buffer or cache in the form of VTLs, disk based backup and bulk storage enhanced with compression, dedupe, thin provision and replication among other functionality.

There you have it, my predictions, observations and perspectives for 2010 and 2011. It is a broad and diverse list however I also get asked about and see a lot of different technologies, techniques and trends tied to IT resources (servers, storage, I/O and networks, hardware, software and services).

Lets see how they play out.

Ok, nuff said.

March and Mileage Mania Wrap-up

Today’s flight to Santa Ana (SNA) Orange County California for an 18 hour visit marks my 3rd trip to the left coast in the past four weeks that started out with a trip to Los Angeles. The purpose of today’s trip is to deliver a talk around Business Continuance (BC) and Disaster recovery (DR) topics for virtual server and storage environments along with related data transformation topics themes, part of a series of on-going events.

Planned flight path from MSP to SNA, note upper midwest snow storms. Thanks to Northwest Airlines, now part of Delta!
Planned flight path from MSP to SNA courtesy of Northwest Airlines, now part of Delta

This is a short trip to southern California in that I have to be back in Minneapolis for a Wednesday afternoon meeting followed by keynoting at an IT Infrastructure Optimization Seminar downtown Minneapolis Thursday morning. Right after Thursday morning session, its off to the other coast for some Friday morning and early afternoon sessions in the Boston area, the results of which I hope to be able to share with you in a not so distant future posting.

Where has March gone? Its been a busy and fun month out on the road with in-person seminars, vendor and user group events in Minneapolis, Los Angles, Las Vegas, Milwaukee, Atlanta, St. Louis, Birmingham, Minneapolis for CMG user group, Cincinnati and Orange County not to mention some other meetings and consulting engagements elsewhere including participating in a couple of webcast and virtual conference/seminars while on the road. Coverage and discussion around my new book "The Green and Virtual Data Center" (CRC) continues expand, read here to see what’s being said.

What has made the month fun in addition to traveling around the country is the interaction with the hundreds of IT professionals from organizations of all size hearing what they are encountering, what their challenges are, what they are thinking, and in general what’s on their mind.

Some of the common themes include:

  • There’s no such thing as a data recession, however the result is doing more with less, or, with what you have
  • Confusion abounds around green hype including carbon footprints vs. core IT and business issues
  • There is life beyond consolidation for server and storage virtualization to enable business agility
  • Security and encryption remain popular topic as does heterogeneous and affordable key management
  • End to end IT resource management for virtual environments is needed that is scalable and affordable
  • Performance and quality of service can not be sacrificed in the quest to drive up storage utilization
  • Clouds, SSD (FLASH), Dedupe, FCoE and Thin Provisioning among others are on the watch list
  • Tape continues to be used complimenting disks in tiered storage environments along with VTLs
  • Dedupe continues to be deployed and we are just seeing the very tip of the ice-berg of opportunity
  • Software licensing cost savings or reallocation should be a next step focus for virtual environments

    • Now, for a bit of irony and humor, overheard was a server sales person talking to a storage sales person comparing notes on how they are missing their forecasts as their customers are buying fewer servers and storage now that they are consolidating with virtualization, or using disk dedupe to eliminate disk drives. Doh!!!

    Now if those sales people can get their marketing folks to get them the play book for virtualization for business agility, improving performance and enabling business growth in an optimized, transformed environment, they might be able to talk a different story with their customers for new opportunities…

    What’s on deck for April? More of the same, however also watch and listen for some additional web based content including interviews quotes and perspectives on industry happenings, articles, tips and columns, reports, blogs, videos, podcasts, webcasts and twitter activity as well as appearances at events in Boston, Chicago, New Jersey and Providence among other venues.

    To all of those who came out to the various events in March, thank you very much and look forward to future follow-up conversations as well as seeing you at some of the upcoming future events.

    Cheers gs

    Did someone forget to tell Dell that Tape is dead?

    Storage I/O trends

    Did someone forget to send a memo to Dell that magnetic tape is dead, or, perhaps pre-occupied with other activities? Maybe no body at Dell read the “virtual” or “fictional” memo that tape is dead?

    Ok, enough with the cynicism and joking around, tape is not dead (See recent Computerworld and Dell story) and Dell is one of several vendors including IBM who still find time to talk about tape as part of a solution to different customer and environment needs.

    Sure, tape might be in or heading into its golden years or what can also be called the plateau of productivity (for customers) or profitability (for some vendors), tape does not get the marketing dollars and media coverage as its been around as a technology for a long time and their are cooler and niftier (techno term) things to discuss including disk based backup and data protection, CDP, VTLs, de-dupe debates, clusters, grids and clouds, FCoE vs. iSCSI, NAS, SAS, virtualization, OSD and pretty much anything except tape.

    However, the reality is that many organizations, particular larger organizations still use and rely on tape based data protection for backup/BC/DR as well as archive for compliance and non-compliance data retention or data preservation activities, in some cases complimenting and co-existing with disk based solutions.

    Disk to disk (D2D) based backups and data protection certainly continue to gain adoption and deployments in both large and small environments, however, the shift to disk based data protection, or, clinging to tape with a death grip does not have to be, nor should it be an all or nothing value proposition, that is, they can and do co-exist for different uses and purposes leveraging the various economics and benefits of the technologies to address various tasks and requirements.

    New and emerging technologies certainly need to be discussed, dissected, developed and deployed as they are the future for maintaining and sustaining business growth via IT service delivery in economical and reliable fashion, that is, apply what technologies makes economic and business sense at a given point in time to minimize risk while maximizing useful benefits to your business.

    Ok, nuff said.

    Tape Talk – Changing Role of Tape

    Storage I/O trends

    Here’s a link to a new article over at Enterprise Storage Forum titled “The Changing Role of Tape” for those of you who still use or care to admit to using magnetic tape as part of your data protection (backup, BC, DR) and data preservation (e.g. archiving and compliance) strategies.

    Disk based solutions continue to grow in adoption for data protection, however tape remains relevant taking on different roles, similar to how disk drives are taking on different roles as FLASH and RAM based SSD continue to evolve and grow in terms of customer deployment adoption. Consequently, despite the continued hype that tape is dead, the reality is that tape remains on of if not the most energy-efficient or green storage mediums of in-active, off-line data in a given footprint and cost basis.

    Tape is still being used in many environments particularly more so in larger environments with a focus shifting towards supporting ultra-dense large full backups that have been copied from disk to disk based backups as well as for archives.

    Disk based data protection particularly with virtual tape libraries (VTLs) that combine data footprint reduction techniques such as compression, de-dupe, replication and migration to tape capabilities continue to gain in popularity as a convenient way to migrate from tape based backups to disk based backup preserving investment in existing people skills, policies, rules and software.

    Ok, nuff said.
