Backup Exec 2010 R3 - Disk to Disk to Tape with Dedupe option - Best Practices
Posted on 2011-09-14
I'm new to BackupExec 2010 and I'm trying to setup a backup strategy for my company's file server.
I have a DELL R710 server with 5.5TB storage capacity, runing Windows 2008 Server x64 and BackupExec 2010 R3 with Dedupe option. I have 4 x 2TB hard drives on RAID 5, and this same logical drive will store both my file servers data AND the Deduplication Folder, which i know is far from being ideal, but due to budget constraints, we could not purchase external disk array storage. (perhaps we will next year). I also have a SAS DELL PV124T connected, and 7 LTO5 tapes loaded and ready to go.
I have to create a backup strategy that backs up from Disk to Disk to Tape, and i would like to know what are the best practices for doing so. I've been doing a lot of googling on the subject.
At the moment my storage requirements are to backup 1.5TB of data from the file server.
Our requirement are as follows:
- Full Backup on Friday, and Incremental for the rest of the week DEDUPED
- Full Backup to tape everyday DUPLICATED
- Each slot on the autoloader should be dedicated to one tape ONLY (for now)
What i've done so far is create partitions on the tape for each slot, so that a backup does not overflow into the next tape.
I've also created seperate media sets for each day's backup (so 7 media sets in total)
So now I've come to main point of actually creating the job and I thought I'd just ping the community for some advice. I've seen some info on creating templates and policies. What would be ideal would be a job that runs the disk to disk dedupe everynight (FULL/INCREMENTAL) automatically followed by a job that run disk to tape duplicated (FULL ONLY). I'm not entrirely sure if this is possible, and if not, we can live with having DUPLICATE incremental to tape.
Appreciate the help.
