Just to chime in: the hotfix did resolve my problem. And so far has had no side effects (well after 12 hours :P )

Minor bug report Veeam 8.

I was running a SureBackup job when i noticed that progress indicator stayed at 0% in the SureBackup job tab, while the progress indicator (% completed) worked normal in running jobs tab.

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.


Hi!

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

Your issue seems to be similar to the one discussed here; might be worth posting your ticket number there in order to get a private fix as soon as possible. Thanks.

Re: Post v8 Upgrade Observations (Case # 00691208)

I registered a case, and uploaded log zip to your ftp.
Hopefully it's the same issue as Lars Pisanec had.

I am seeing the same backup time issues. They are taking way longer in the two environments I've upgraded to Veeam 8 on. A backup that used to take an hour on Veeam 7 now takes 3.5 hours. I am actually getting better throughput on veeam 8 at 102 MB/s vs Veeam 7 where the processing rate was 45-55 MB/s. Should I open a support case on this?

Yes, you can and send all job logs to review bottleneck stats, amount of changed data and other statistics that would allow us to understand where this difference comes from.

I am using Forward Incremental keeping 60 days of retention if that helps. It is not a SAN environment (Dell PowerEdge server approx 6 months old with 16 drives and plenty of iOPS). We are using vCenter 5.5 Update 2. Nothing changed infrastructure wise prior to upgrading to Veeam 8.

Thanks,
Patrick

@patrickl78 - my issues seems more or less identical to yours, forward incremental, local disk and 5.5u2. No infrastructure changes prior to upgrade.

I´m currently working with Veeam support on this. I actually installed the fix for bug 38623, wich improved performance a bit (from 4-5 times slower to appr. 2-3 times slower).

Still - I installed v8 expecting better performance and not much worse. Currently waiting for support log analysis.

Jimmy,

I have a case open as well and have sent in the logs for the two servers I upgraded. On both servers I upgraded I also run replication jobs and those jobs get the weird Exchange truncating error even though the servers have never had Exchange on them.

Thanks,
Patrick

Implemented the hotfix yesterday.
The backups used about 3 hours less time now, so this seems to have done the trick.

Applied the bug fix today with Veeam support. Backups ran successfully but still 3.5 hours. It cut the backup window down by an hour but no where near the usual 1 hour and 15 min on Veeam 7. Support did confirm I was impacted by the issue the bug fix was targeted at but it has not alleviated all of my issues so far. There is a second bug that there is currently no fix for as i understand it from support. I'll upload my logs again to them once this job finishes and hopefully will help them figure out what is going on. There have been no changes to my network infrastructure or backup job prior to the upgrade.
