Duplication Job of 2008 R2 AD Server to Dedup device runs very slow
I am backing up a Windows 2008 R2 AD server using Backup Exec 2010 R3 SP2 with all the latest hotfixes. The Backup process runs at an acceptable speed (18GB @ 15m) but the duplication job (which is duplicating to a BE deduplication device) runs very slow (same 18GB @ 2h45m). This also occurs on two other AD servers (seperate jobs). All other jobs perform fine. This is not a corrupt catalog issue, as I have tried a fresh catalog directory with no impact. Also this occurs for both a Dedup destination and a Backup-To-Disk destination.
