Somehow I had a database corruption and I did not know how to restore from backup. It was a bad experience until I saw that it worked. Make regular and check your backups.

Somebody tell that to tindie !
rule of thumb. any backup you don’t regularly test isn’t a backup.
An untested backup is not a backup, it’s a wish.
Also known as Schrödinger’s Backup.
Schrödinger did not have a backup cat.
But he had quantum entanglement
Well, he did and he didn’t…
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…
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.
How do you guys test your backups?
The image backups I do of my server are tested in a VM
That’s a gimmie. I test server image backups in a VM. So far, I’ve never had to resort of a backup, but I don’t want to find out that my image is worthless if I ever had the need.
this drove me nuts at workplaces. we have to test the backups after backup. so many did not want to waste the resources. if it worked fine once it will always work fine to them.
Sounds like there’s room for a tool that checks backups
or ai that evaluates. For me the backup works if the whole system actually works. Its more commonly known as disaster recovery.
Narrator: The fire detector in fact did not work.
There’s more than one kind of backup in life, check them all.
That’s one I’d have the facility owner hire someone to test.
