File level Backup

Question

Looking for opinion on bets way to do file level backup and store the date of site.

Thinking of attaching iscsi lun to the backup server. Using arcserve backup all the data to that lun. replicate the lun to dr site.

is this correct approach or there is a better way of doing it to insure data backup and it is off site.

we are doing approximately 2 TB a week
Looking for some compression so I can keep more than 2 month of data or even 3 month.

Please suggest the best way to accomplish it with Celerra 5.6

i don't think you want to present your iSCSI lun to another server unless you have some kind of clustering going on. I am thinking that you could promote a snapshot of your iSCSI LUN , mount it on the backup server and spin it to tape. When the backup job is done, un-mount it and de-mote the snapshot. Rinse and repeat . Keep in mind though that when you run a backup against your iSCSI LUN snapshot ..you are essentially running it against the primary iSCSI LUN as snapshot is nothing but a bunch of pointers to your primary LUN. So you might see slightly degraded performance but it would be the same if you ran it against the primary iSCSI LUN anyway. The benefit of running it from a snapshot is that you have a point in time copy of your data, no open files ..plus you offload the burden on the CPU/Network/memory to your backup server.

I am currently using the old but still good IBM Fiber san.
Backing up all the data locally to the fiber attached drives.
the thing is that it is a local backup solution but does not take my backups off site.
I thought it would be possible to achieve this with Celerra but maybe not.
Replication will not work because to much data and we need to keep around 2 month so there must b compression of some sort.
Also what is the best way to backup VMs. If VM has crashed instead of bulding a new from template and would like to restore the entire VM guest and than restore the latest file level backup to it

you have to explore solutions that support VCB backup, not sure but i believe arcserv supports it.So are you vaulting tapes off site ?

kaba1 · Answer

might work. do you know if it does block level backup?

dynamox · Answer

have you considered MozyEnterprise ? Great dedupe http://www.emc.com/products/detail/software/mozyenterprise.htm

kaba1 · Answer

we are taking the tapes off site oursalves. Not a best solution

dynamox · Answer

yep, block level incremental.

There are lots of ways of doing thisThe 'best way' really depends on your environment, requirement, budget,...I'm sure your local EMC Technology Consultant can give good advice for your setupSome of the options:Avamar - great dedupe/cmpression for lots of days to keep, doesnt need a backup software, talks to Celerra using NDMPanother Celerra on the DR site, replicate the data and keep checkpoints therebackup software with B2D that uses local storage or storage that gets replicated to the DR site (like Arcserve with B2D option that uses CIFS/NFS storage)EMC Disk library - with dedupe/compression - can be placed on the DR site or replicated therelocal backup to tape or disk and clone the tapes to the DR sitelocal backup that writes directly to disk/tape/disk library that is located on the DR site .........

I'm not sure what types Arcserve supports as B2D targets - others like Backup Exec, Netbackup, Networker, ... do support CIFS (UNC Path) or NFS volumes as well
