we are using symantec backup exec 2012.
File server around 1.5 TB data Lunned from SAN as local storage in file server.
It has taken more than 40 hours with low job rate.Please help me shirtout the problem.
Does the 1.2TB consist of very small files and millions of them? You may be out of luck. The only thing that wouldd fix that, is NetBackup. dense file systems cause havoc with traditional backup applications.
The only products that can get around this include Symantec NetBackup FlashBackup technology, EMC Avamar, and EMC Networker SnapImage module. I believe BackupExec 2012 lost support for Storage Foundation FlashSnap that could aid in this. BE2010 was the last version to support it.
Perhaps break up the job into smaller pieces, 4x400GB jobs that run concurrently, and backup to disk then to tape?
