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

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.
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.
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.
