Comment on Proxmox Backup Server VM crashes take down host - any idea why?

Smash@lemmy.self-hosted.site ⁨2⁩ ⁨weeks⁩ ago

I recently learned that during a snapshot backup, all subsequent writes are done on the VM and the Backup server until the backup is finished. So if you have the slightliest performance problems with your backup target, you’ll have increasing I/O delays which can result in timeouts and intimately kernel crashes on the host.
