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.

An untested backup is not a backup, it’s a wish.

Schrödinger did not have a backup cat.

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.

Two backups is one and one is none.

Two untested backups are worse than one tested backup though.

Narrator: The fire detector in fact did not work.

There's more than one kind of backup in life, check them all.

3, 2, 1… Test the backup!

… Is that the rule, right?

illusionist@lemmy.zip on 18 Apr 16:59 next collapse

From now on!

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

I run Borg backup, and I did a successful live test yesterday. Deleted the wrong file and hade to restore it.

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.

rule of thumb. any backup you don’t regularly test isn’t a backup.
