Please god don't use Backup Exec if you have an environment that you want to be at all reliable. Mysterious problems with backups hanging forever in queue once you hit 9TB or so on your dedup folder, plus size limits and the limit of one dedup folder per media server which, as it turns out, can never be moved to another media server ever. (Though apparently DoubleTake replication has worked to move mine off of an ailing backup server.) Also, RAM hungry β but so is any dedup software.
We're now working on a switch to Commvault. Biggest downside there seems to be cost but it's looking like one of those "get what you pay for" kind of things. I was also very impressed with the Exagrid appliances too β from what I remember you just dump a full uncompressed backup to their landing area and they take care of all the compression/dedup for you. The College of Human Medicine has several of them. Once again, major limitation there is cost. ---- Jack Kramer Computer Systems Specialist University Relations, Michigan State University w: 517-884-1231 / c: 248-635-4955 From: Paul Hutchings <paul.hutchi...@mira.co.uk<mailto:paul.hutchi...@mira.co.uk>> Reply-To: NT System Admin Issues <ntsysadmin@lyris.sunbelt-software.com<mailto:ntsysadmin@lyris.sunbelt-software.com>> Date: Tue, 1 Mar 2011 09:49:35 -0500 To: NT System Admin Issues <ntsysadmin@lyris.sunbelt-software.com<mailto:ntsysadmin@lyris.sunbelt-software.com>> Subject: RE: Backups/deduplication Have a look at Commvault or Backup Exec, possibly NetBackup too. They will all do dedupe to disk within software β you might find it offers a lot more flexibility at a lower cost than a hardware appliance, plus lower growth costs. We use Commvault, ask away but in two words, itβs good.

From: Tom Miller [mailto:tmil...@hnncsb.org] Sent: 01 March 2011 14:32 To: NT System Admin Issues Subject: Backups/deduplication Disclaimer: I know, I know, it's been on the list before. I checked the archives and didn't see what I really need from you folks. I'm in the market for a deduplication device. My LTO changer died recently, so this is a good time to change. I've been looking at the following: - Barracuda Backup 890, optional "cloud" storage can be purchased - EMC DD610 - Exagrid EX 3000/4000 - Overland SnapSAN - HP Storageworks Comments on the above? I want to do the usual: point my backup software to it, let it run. I will eventually need a second unit so I can replicate to a second location, so replication software/technology is needed. We have typical data here: files, e-mail (not Exchange, so file-system only), databases, XenServer VM images, etc. Currently running about 2 - 3 T per full backup. We retain data for one year before overwrite. Any favorites, any to avoid?
