Slow backup speed to Dedupe

[bst740]

Hello! We have BE 2015 (14.2 rev 1180) with a problem of slow backup operations. We have a clustered file server, with empty file structure as client. At BE we have 2 disk storages: 1) Deduplication disk 2) Advanced disk All this disks are presented via the same storage system on raid 5 by SAN. I think that storage is not a bottleneck. When we make backup to dedupe, it goes for ~20 Minutes (Empty file system on client!) If we change the destination to advanced disk, it goes only 30 seconds, I think it's a normal speed. The long operations on backup to dedupe are: Queued ~ 2 minutes Loading media ~ 10 minutes Verify ~ 10 minutes How can we improve performance for dedupe disk? Thanks!

Is any AV perhaps not scanning the dedupe folder? If so, put in an exclusion for this.

Also, what are the specs of the media server in terms of RAM and CPU?

Thanks!

OK cool...how is the fragmentation on the drive hosting the dedupe volume?
