How do you guys test your backups?
I have restored my proxmox setup from backup and it worked, but that is not something I do on regular basis.
I have from time to time done spot checks that certain files are working.
Most of the time I rely on the verification done by proxmox backup server..
The image backups I do of my server are tested in a VM
PBS verification is only a checksum of file integrity. If somehow the backup was zero-length, or was otherwise corrupt, the verification would succeed but the backup would be useless. How often you do file or full restores is up to you, but required for actual verification.
