Well, firstly, try doing a performance baseline on your Backup Exec/DC server. Try to see what the processor utilization and disk utilization looks like before and during the backup.
Also, check task manager to see if there are any processes running wild.
Otherwise, try doing a backup with NTBackup and see what kind of speeds you get that way. It'll help to determine whether this is a Backup Exec or hardware related issue.

Latest info:
I have similar situation. SQL backup runs fast, with lighning speed.
Byte count : 331,980,242,048 bytes
Job rate : 4,109.00 MB/Min
Domain Controller file backup runs extremely slow. Both to tape and B2D are slow (with BE12.5)!
Byte count : 3,632,690,441 bytes
Job rate : 14.49 MB/Min (Byte count of all backup sets divided by Elapsed time for all backup sets)
Files : 78,338
Directories : 131,868
(I've monitored this job number of times, the speed grows to almost 900MB/min in five minutes, it writes almost 1.7GB, and then starts dropping, and the whole operation lasts 3:10 hours.)
Same if I run full backup - the difference is that the speed is 364.00MB/min for 260GB of data, 11:49hours.
Network issue - it is not, I am copying a 2.5GB file from the DC to the backup server in 1:50min
Noncentz, did you find out anything more?
I applied SP2 for BE12.5 two days ago.
Hint?
I set the buffers to 1MB. Unchecked single read and write checkboxes on each tape. Have LTO4. No change.
Thanks
