Deleting Failed Backups via CLI

[sergioposadam]

Hey everyone,

I'm managing backups on my PBS and I've run into a bunch of failed backups that I need to delete. I've attached an image showing the list of backups with their statuses – you can see the failed ones marked in red.

Can anyone guide me on the specific commands I should use to delete these failed backups?

Thanks a lot for your help!

proxmox-backup-client snapshot forget ...

Thank you for responding.

That command will help me delete specific snapshots, but if I have 50 VMs, I don't want to see the GUI for failed backups and run the command one by one. How can I identify which ones have failed from the CLI?
