We've got a strange issue with our Backup Copy Jobs lately:
We made a Backup Copy Job from our normal Backup Jobs which is now running since a month.
The Size of our Backup is about 1.7TB -> The size of the Backup Copy is about the same.
Five Days ago, the "Transformation" of the Backup Copy Job started (I think this is the merging of the incrementals to a new Full?)
Anyway, it proceeds about 1% Every 4 Hours, now its at 30% (after 5 Days running!) thats horribly slow.
The source of the backup and the backup copy are on the same drive (iScsi LUN provided by our Synology NAS), maybe this make some problems?
In the ressource monitor of the veeam server, I see in the disk performance, that the backup job file (vib/vbk) is continuously in write and read access.
The network and processor utilization however is pretty low, so it looks like he's struggling with reading and writing any faster.
Further do we have the extreme compression activated. Our normal Backup Speed is at approx. 250MB/s (so I think generally its not that bad configured

Our Environment:
Backup Destination: Synology RS10613xs+
Disks: WD Red
Veeam + Proxy Server: HP DL360 G7 with 60GB RAM and 6 (12 virtual) Cores
Source: 2 x HP Dl580 G8 (But the Backup Copy Jobs don't touch this Servers)
If anyone has an idea, what could cause this slow speed, i'd be glad for any suggestions.
Best Regards
David
