Backup Exec extremely slow to verify domain controllers
Posted on 2011-03-08
I'm running Backup Exec 2010 R2 on a Windows 2003 R2 Standard x64 box, using the deduplication option. I am backing up to a storage array that is physically attached to the backup server.
The problem I'm having is that the verify jobs for the domain controllers only are *extremely* slow. I understand that it is slow to verify a deduplication job but here are some statistics for you.
Server 1 (non-DC) backup: 1945MB/min verify: 253 MB/min
Server 2 (DC) backup: 620 MB/min verify: 35 MB/min
As you can see this is completely ridiculous.
I've tried shifting the verify processing from server to client but it makes no difference.
I need to fix this because the verify jobs keep getting cancelled so that the next backup can start and I have to time to replicate offsite.
(If you have any ideas to speed up the regular verify jobs too, I'd be appreciative.)
