Delete orphaned backups

[janvv]

When I delete a VM or LXC, then the backup is not deleted along with it.
My backup disk is having a lot of backups that do no longer belong to an existing machine.
The pruning system doesn't take care of that either.

What is the best way of cleaning those old backup files?

For Vzdump backups just open the folder that you use as your Vzdump backup storage and delete the files you don't want anymore. With PBS backups they are still listed in the PBS webUI and you can use it to delete them.

hmm... I was hoping to find a way (or a shell script) to select backup files that do not belong to an existing machine.
In my retention scheme, backups will be removed when they are older than 1 week. So I will add a cron job to clean up files having -mtime +7. Then I do not need to do anything manually.
