VM becomes unresponsive during Veeam backup

[gasherbrum]

Tested with an independent SSD for Veeam snapshot storage, the VM still crashes for me

Issue was fixed for me with the following:
C:\Program Files\Veeam\Plugins\PVE\Service
Edit appsettings.json

VmbApiPreReadQueueDepth - change from 32 to 4, restart services

We have fixed this issue by creating a seperate volume on our storage cluster for Veeam snapshots.
Now Veeam will not write its snapshots to the local disk of Proxmox anymore, but to our NVMe storage cluster (during backups)

Just asking - why dont use the Proxmox Backup Server ?

Hello, might I ask what led you to this particular setting?

That sounds interesting.

We use many more Veeam products and features.
VSPC, Cloud Connect etc.

Proxmox Backup Server is not able to give us all features we need in our multi-tenant private cloud.

Veeam support suggested this - seems to work for me and the VM is still performant during backups

PBS does not have immutable backups to S3, nor replication, and also missing some windows integrations such as SQL db processing
