Please note that sequential write workload cannot represent storage performance, which is measured in IOPS. However, backup storage is not necessarily causing the issue anyway, see what the backup job reports as a bottleneck.
This is absolutely true, but since nothing else has changed I just made sure that storage was ok.
It seems that the speed is permanently dropped, so backing up my file server takes now 70-80minutes instead of 25-35 minutes. It doesnt seem to have much impact if vbr has to transfer 7GB or 70GB. Anyway, I can wait for the patch #1, since my backup window is quite big.
Other thing I noticed, all my backup copy jobs to tape device fails now. Opened a Support case on this one.
Tape library: IBM 3573-TL A.40
Used tapes: FOE329L4 [FOE329L4]
GetTapeHeader failed ChannelError: ConnectionReset
