Backup issues after vCenter upgrade to 6.7
Hi
We have started to see backup issues on mainly large vms after upgrading vcenter to 6.7 (not U1). We are seeing the same errors on 2 virtual environments where both have vCenter version 6.7. Esxi hosts are not yet updated.
Case: 03293359
Error: VDDK async operation error: 2....
Cause: This happens on vms with atleast 5-6 harddisks. In vcenter 6.7, VMware have set a hard read buffer size limit (32 MB) that is not possible to change. When backup runs parallel on a vm with many harddisks this read buffer size is overcommited and backup fails. More info https://support.unitrends.com/Unitrends ... /000005944
Case: 03295615
Error: NTFS file: failed to read 16777216 bytes at offset 16779072 Failed to upload disk.
Cause: Started to happen after vCenter was upgraded to 6.7. Still investigating root cause with Veeam support.
VBR 9.5 update 3a
VMware strikes again!

Hi,
Always best to open a support case. You will be surprised how quickly most cases get resolved once the logs are inspected by support.
Thanks

Magnus already has a case opened and, as far as I can see, some of the engineer's suggestions did help, so it is being further investigated.

Re: Backup issues after vCenter upgrade to 6.7
Hi, i know this is an old topic but what was the solution? I have the same problem :
Processing FILES_01 Error: NTFS file: failed to read 16777216 bytes at offset 0
Failed to upload disk.
Agent failed to process method {DataTransfer.SyncDisk}.
Support suggests to do a check disk but the machine can't go offline in this period.

Re: Backup issues after vCenter upgrade to 6.7
Veeam support provided a hotfix for the customers with that issue. This hotfix was later integrated in our Update 4. So please download and install Update 4a as a solution.

Andreas,
Just wanted to mention that we are on 9.5 4a and are seeing this issue as well on multiple servers. I am opening a case with Veeam support now.

Re: Backup issues after vCenter upgrade to 6.7
Solution for us was a regfix that we got from support. Update 4a did not solve our issue. Not sure if I should add the regfix here..?

Hi Magnus, I'd first consulted with support since it was supposed that the fix was included in subsequent updates.
