Optimizing Deduplication Performance Featured
Regarding Gary Parker’s recent blog, Deduplication - The Power of Flexibility, Gary discusses the importance of data deduplication and the trade-offs among the various deduplication options that are available in the market.
An interesting point was the comment that “for the highest performance levels, a recommended best practice is to use flexible deduplication policies to leverage post-process deduplication for the initial backup (for speed), and then switch to inline deduplication for subsequent backups.” I would like to expand on that because it is an important element of a good deduplication implementation.
Inline deduplication has the primary benefit of minimizing storage requirements, reducing them by as much as 40 percent. It is ideal for small storage configurations or environments where immediate replication is desired. For the highest performance levels, a recommended best practice is to use flexible deduplication policies to leverage post-process deduplication for the initial backup (for speed), and then switch to inline deduplication for subsequent backups.
Post-process deduplication is ideal when your key goal is to back up as quickly as possible. As its name implies, it occurs after the backup process completes, thus it can be scheduled to run at any time.
Today FalconStor announced the latest version of its industry-leading deduplication solution, FalconStor Virtual Tape Library (VTL) 7.5.
In performance tests with a four-node cluster, FalconStor VTL 7.5 demonstrated the fastest sustained deduplication speeds in the industry: more than 28 terabytes per hour with inline deduplication and more than 40 terabytes per hour with post processing deduplication. And an array of options, including inline, concurrent, and post-processing as well as Turbo capabilities, let you optimize performance for your environment. All this makes FalconStor VTL not only the fastest but also the most flexible deduplication solution on the planet!
Beyond speed and flexibility, FalconStor VTL 7.5 also delivers greater scalability, efficiency, and security – all the right functionality to optimize IT infrastructure, effectively manage data growth, and align data protection processes with business goals.
Bottom line: If you take the features that FalconStor provides – a broad selection of libraries and tape formats, flexible deduplication, and high availability with secure replication from point A to point B – FalconStor provides more functionality than anyone else.

Who says tape is dead! Featured
I find it quite interesting in my travels how some folks are drinking the Kool-Aid that tape in general, and VTL in particular, are dead-end technologies. The argument is that tape sucks for backup, is hard to manage, and you need a LOT of it – so just backup to disk, dedupe, and be done with it. The argument against Virtual Tape Libraries is, why put in a technology that looks like tape if your goal is to get away from tape backup? Sounds like a good argument, right?
Except for some fairly important points.
Let’s do a little word association, shall we? When I say, “tape-based data protection,” what comes to mind? Anxiety! Pain! For many data center managers – particularly those working in virtualized environments – “backup” “pain” and anxiety are words that go together far too easily.
In a world hurtling towards the virtual, tape is a relic. Consider the evidence: tape cannot deliver on-the-spot data recovery. It demands a back-up process that taxes the CPU and network resources already allocated in a virtualized environment, making a lengthy process even slower. And its failures have been well documented; most recent studies find that as much as 40 percent of all backups to tape are unrecoverable.
