How come you're looking at NAS rather than just shovelling a few 2tb drives in your backup server?
I'm looking into doing something very similar myself (we use Commvault/Simpana) and the rule of thumb on disk space, assuming you're not paying per Tb stored, is disk is cheap, and with dedupe rates what they are for average data, you'd be mad not to shovel in as much as you can afford and leave tape as the very last resort. -----Original Message----- From: Roger Wright [mailto:[email protected]] Sent: 04 February 2011 18:08 To: NT System Admin Issues Subject: Dedupe Thoughts? I'm looking at some options for a "poor man's" deduplication system for backups. A Data Domain or Exagrid solution would be preferred but not feasible at this time. We're currently backing up a little over 4 TB to LTO3 tape and have outgrown our backup window, library capacity, and RTO. I'm thinking of using BE 2010's Deduplication option for the engine and something like the Synology DS1511+ with 5 - 2GB drives for 8 TB of storage (w/RAID5 or just a hot spare). Then I could offload to tape for off-site storage or script replication to another unit at a branch office. Any best practices thoughts for sizing the storage for the deduped data? Does it just depend on the ratio achieved and the storage and the number of backup sets retained? One nice thing about the Synology system is it can be easily expanded to up to 15 disks. A Data Domain or Exagrid solution would be preferred but not feasible at this time.
