Exchange 2010 backup REALLY slow
We have some customers complaining about how slow is Exchange Backup Jobs is with Backup Exec.
I have visited both of them and they were using the following (64 bit):
- Exchange 2010 SP1 (both VMs).
- BE 2012 to SATA DAS array / BE 2010 to FC 8GB SAN array
- Gigabit network.
No tape autoloader / drives involved. We are backing up using RAWS agent instead of AVVI (We are not using AVVI yet because there were some trouble implementing it (but it seems I managed to go through it with some help from here)).
The Exchange backup job starts and stops normally. However, the reported backup rate is an awfully 88 to 100 MB (yeah, MEGABYTES) per minute. It does not happen to the file system on the same server (there, it jumps to a really awesome rate of 4900MB per minute).
There are no bottlenecks, nothing wrong with their network / server and I have run out of ideas why is it SO slow. No technotes, nothing in the forums.
Thanks a lot for your help!
