Numerous "DataTransfer" errors in backups

Post by kestis »

VMware environment. Production backup jobs are split up by criticality of servers - all servers hosted in the same HA cluster with storage on the same storage arrays. VBR server and all proxies are physical. Priority 1 VM job and physical server job backing up fine, all other production VM jobs are failing. VM jobs are set up with their own SOBR targeting extents on the same ReFS volumes.

I contacted Veeam support and their response was to run an active full against the VMs that are failing - which seems to be the go-to response for all my recent tickets with them. I decided to go one better carved out some new ReFS storage for some new extents, a new SOBR, and a new backup job for these VMs. I'm running into the same issues.

Again, VMs live on the same hosts, in the same storage arrays, and are being backed up with the same job configurations on the same VBR server using the same proxies. Given this information, I'm inclined to believe it's not a network problem.

Some of my errors:

Please share the support case ID. What you've shared doesn't look expected and should be investigated closer - I'd recommend escalating the case for further analysis.
