Deduplication Option

Created: 27 Jun 2013 | 3 comments

My backup servers have 3TB of internal drive space for B2D.

I then have a single direct attached library with two FC LTO-4 drives.

Can i use the Deduplication option or does it require a SAN?

It does NOT require a SAN.  Simply an NTFS formatted volume.  Make sure it's fast disk, able to write at greater than 100MB/s.  Ideally 200MB/s.  The dedupe engine is rather slow being single threaded and most often disk bound.

There is an online portal, save yourself the long hold times. Create ticket online, then call in with ticket # in hand :-) "We backup data to restore, we don't backup data just to back it up."

Also, take a quick look at my blog on Deduplication Requirements for more info.
