If companies thought that times were tough over the last few years, 2009 is shaping up to be a doozy. Corporate layoffs, cutbacks in spending and decreased revenue coupled with the looming threat of more government regulation and oversight will make the last few years seem like a cake walk compared to what is to come. But as companies prepare to make even more cutbacks in IT staff and budgets, the "Do more with less" mandate that seems to accompany every round of corporate cutbacks remains. This directive leaves IT survivors needing to identify technology providers that can help them better manage their company's data, recover their enterprise applications more quickly and perform these tasks with minimal training, time and effort.

The statement that "data growth is continuing at an exponential rate" rarely ever conveys the exact location of the data that is growing so fast. But it just so happens that a consensus of industry analysts agree the majority of this rapidly growing pool of corporate data (up to 60 percent) now resides at remote corporate offices. While more companies now recognize that the data created and stored at remote sites is vital to their ongoing success, protecting it presents a unique set of challenges. Of these challenges, moving backup data over corporate WANs is one of greatest. (read more)

Too often one of the requirements in the enterprise data protection equation for corporate remote and branch offices (ROBOs) is "rip-and-replace." While this approach is fine for dealing with aging hardware and software, it ignores the majority of scenarios where ROBOs have hardware or software that they can't afford to replace but are being asked to rip out anyway in favor of OEMs' latest solution. ROBOs are just as apt to want a "bolt-on" solution that enables adding new technology to their environment while continuing to use what's already in place. The latter scenario is what Overland Storage's announcement of its REO Compass is designed to provide. (read more)

As disk-based backup and deduplication becomes more popular in the backup process, it is a natural next step to want to move data off-site. Whether this motivation is driven by disaster recovery requirements or centralizing backup data, replicating data from one disk-based subsystem to another is growing in popularity. It is as companies look to implement replication as part of their disk-based backup solution, especially when replicating data from remote and branch offices to central offices, that concerns about bandwidth availability inevitably arise.

The Swiss Army Knife's endearing legacy is that of a tool that has helped everyone from soldiers in the late 1800s to astronauts in the twentieth century deal with whatever situations they might encounter. Of course, part of its appeal is being a low-cost, lightweight, multi-faceted instrument that provides a multiple of options. Much of its cool factor comes from its design to handle whatever challenge an individual might confront. Today's SMBs face similar challenges. SMBs are entering the largely unknown worlds of D2D2T (disk-to-disk-to-tape) and network attached storage (NAS), for which they need their own version of a Swiss Army Knife to offset the complexities that these storage environments create.

The ease in which HYDRAstor's underlying grid storage architecture gives companies to migrate to higher capacity and faster performing hardware found in its new HS8-2000 make it easy to overlook some of its other new features. Part of the reason I devoted the last blog entry to HYDRAstor's self-evolving architecture is because I usually have to do just the opposite: educate readers about the advantages of upgrading to a new product so they can justify the pain of going through the migration. In HYDRAstor's case, it is so painless to upgrade and migrate to the new HS8-2000 release that it is almost easy to overlook its new features. (read more)

Enter FalconStor with its NSS Virtual Appliance, which is the first software vendor to receive this ratification from VMware in the SRM landscape. FalconStor brings a very open approach to this solution. By placing a FalconStor NSS appliance in between the ESX Server's and the storage farm the solution can now become truly hardware independent as the FalconStor appliance can virtualize some or all of the storage on the back-end.

Anecdotal evidence gathered by DCIG suggests that 50 percent or more of all companies deploying disk-based storage systems in multiple sites as backup targets are also opting to purchase replication software that replicates data between sites for enhanced data protection. For many companies, this purchase may represent their first foray into replication of any kind. As a result, it's not surprising that many are unprepared for the types of questions to ask when selecting replication software or what to expect from the accompanying management software. (read more)

Replication and deduplication are features that are fast becoming necessities when disk libraries are introduced into enterprise IT backup environments. But as I brought out in a previous blog entry, introducing multiple functions into disk libraries intended for enterprise caliber backup environments typically has some unpleasant trade-offs. A primary concern in enterprise IT shops is how large (or small) to initially configure the solution so companies neither overspend on oversized hardware nor purchase undersized hardware that cannot scale to meet their future requirements, so they need some way to forecast how their IT environment is going to look going forward.

Overland Storage's recent acquisition of the Snap Server line of NAS storage products from Adaptec breathes new life into a product line that had all but faded from view. Adaptec's lack of focus on the Snap Server line coupled with its changing message about what it intended to do with it made Snap Server a logical acquisition target for Overland Storage, which was actively looking to add NAS to its portfolio of disk-based backup products. But now that Overland Storage has it, the big job of explaining how Snap Server fits into customer backup environments falls to Steve Rogers, Overland Storage's Director of Product & Solutions Marketing.

The requirements for providing higher, faster and easier means of enterprise business continuity have escalated dramatically in the last decade while the criteria for selecting the software remains rooted in yesterday's premises and assumptions. Today's corporations not only need to re-evaluate what software they are using to perform these tasks but even what criteria on which they should base these decisions. The last six criteria covered in this blog entry provide readers a list of base line features that they should look for when picking backup continuity software and how well InMage Systems delivers on meeting these new requirements for enterprise distributed business continuity.

The pressures to implement business continuity software that can span the enterprise and recover application servers grow with each passing day. Disasters come in every form and shape from regional disasters (earthquakes, floods, lightning strikes) to terrorist attacks to brown-outs to someone accidently unplugging the wrong server. Adding to the complexity, the number of application servers and virtual machines are on the rise and IT headcounts are flat or shrinking. Despite these real-world situations, companies often still buy business continuity software that is based on centralized or stand-alone computing models that everyone started abandoning over a decade ago. (read more)

Any type of business continuity software that a company uses has a catch: the first task after the software is installed is to create a full copy of the production data at the disaster recovery (DR) site. What options the business continuity software provides to copy the data to the DR site is of a primary concern to businesses since it impacts what data is copied, how much data is copied and what type of planning companies have to do ahead of time. (read more)

Selecting the right business continuity software can rank right up there as one of the more difficult decisions that companies face. No two companies have exactly the same environment or business continuity requirements and rarely is there a meaningful way for any company to quickly and effectively test business continuity software across all of the applications in their enterprise. As a result, companies are often put in the position where they need to select the best software for their environment with only some of the facts in hand and then hope they don't live to regret the decision.

The enterprise data center continues to evolve, driven by ever-growing amounts of data and new demands for data availability - local and remote. These demands are driving companies to identify alternatives to existing data protection methods with deduplicating disk-based storage systems, such as Quantum's DXi Series, becoming a preferred backup target. However deduplicating data is only half the equation. To fully deliver on enterprise data protection, companies need efficient, cost-effective options so they can move this deduplicated data off-site for long term compliance and disaster recovery, or centralize and consolidate data from remote offices.

Almost any disk-based solution - deduplicating or otherwise - is going to expedite backups and recoveries. Sure, some solutions may deduplicate better or do it faster but at the end of the day most companies are at the point that putting in place any disk-based system that supports replication and deduplication is better than dealing with the current backup pain. However what companies often fail to account for is how fast their backup data stores grow when they start backing up data to disk. More than once I've talked to system administrators in companies where "undisclosed" or "hidden" departmental application servers start to come out of the woodwork once department managers hear that corporate IT backup processes actually work.

The one I want to focus on in this entry is Televaulting's new replication functionality. Replication is a key function in any facet of the storage landscape and, with Asigra adding this feature into its latest release of Televaulting, it becomes an even more robust player in the enterprise space.

The juxtaposition of deduplication and replication in disk-based backup appliances is a powerful combination that companies can use to protect backed up data across data centers as well as data backed up at remote and branch offices (ROBOs). Yet where deduplication ends and replication starts can get a little confusing in grid storage architectures such as is supported by the NEC HYDRAstor that features global deduplication capabilities.

Deduplication is currently one of the hottest topics in data protection but it takes more than one form. The CommVault® Simpana® software suite implements deduplication as a Single Instance Store (SIS). In this iteration, SIS deduplicates archived and backed up files at the file level and then only stores one occurrence of the file. In part 2 of this interview series with CommVault Systems' Senior Director of Information Access and Management, Simon Taylor, elaborates on how Simpana leverages SIS for information search and data mobility as well as how this approach complements block-based deduplication approaches found on certain disk-based storage solutions.

It is easy to understand why disk-based backup solutions such as Quantum's DXi Series are growing in popularity as a primary target for backups. Disk shortens backup times, expedites recoveries and removes the inconsistent results that tape delivers when used as a primary backup target. However the difficulties that arise with using disk as a primary backup target are less intuitive. Disk solves the immediate pain of backup but creates other less intuitive, longer term data management issues. (read more)

At recent storage conferences (Storage Decisions, Storage Networking World, etc.) replication has emerged as a hot topic of discussion among end-users. In talking with these different users and listening in on a number of end-user panel discussions, there are a number of factors that they attribute to their increased interest in using replication as part of their company's overall disk-based data protection strategy.

Backup to disk is now seen as "The" solution for any company looking to solve its backup problems. Factor in deduplication as part of the disk-based backup solution and it is easy for companies to believe that they are well on their way to solving their backup problems. To a certain degree, that's true. Introducing disk almost always solves the immediate corporate pain of failed backups while shortening their backup windows. In fact, I am only aware of a few, isolated instances where that is not the case. (read more)

A survey that appeared in the May 2008 issue of Storage Magazine indicated that DR testing is not routine for all business. That's probably the understatement of the year. Of those users surveyed, fully half (48%) do not regularly perform testing and, of those that do, they most often test those applications deemed "mission critical". (read more)

Quantum is aiming for the enterprise with its deduplication technology and looks to make a serious run at the enterprise datacenter with its DXi7500. Designed to anchor Quantum's deduplication strategy, companies can use the scalable DXi7500 when it is receiving replicated data from Quantum's DXi3500 or DXi5500 appliances in remote offices; replicating to disaster recovery site(s); or deduplicating terabytes of data during nightly backup jobs in the datacenter. To accomplish this, Quantum designed the DXi7500 to become the focal point for its DXi portfolio. (read more)

In the face of these fundamental shifts among corporate data centers in server data protection and virtualization, data protection software needs to do more than just adapt. It needs to embrace backup-to-disk and server virtualization in order to transform data protection software into an information recovery platform. That is exactly what today's 8.0 release of Asigra Televaulting brings to the table in the following ways: (read more)
