Unable to remove a snapshot

[nounours54]

Hi.
I've restored from tape a single snapshot.
It was fully fonctionnal, as I was able to restore the VM into PVE and run it.
Now, I want to remove the snapshot built from tape, but it doesn't work :

Apr 30 12:13:55 pbs1 proxmox-backup-proxy[825]: removing backup group "/mnt/datastore/LUN-PBS1/ns/Joffre/ns/Cloud/vm/200"
Apr 30 12:13:55 pbs1 proxmox-backup-proxy[825]: DELETE /api2/json/admin/datastore/LUN-PBS1/groups?backup-id=200&backup-type=vm&ns=Joffre%2FCloud: 400 Bad Request: [client [::ffff:127.0.0.1]:58450] while destroying snapshot 'BackupDir { store: "LUN-PBS1", ns: BackupNamespace { inner: ["Joffre", "Cloud"], len: 12 }, dir: BackupDir { group: BackupGroup { ty: Vm, id: "200" }, time: 1767314061 }, backup_time_string: "2026-01-02T00:34:21Z" }'

Please notice I'm usually able to manually remove snapshots, and I cannot remove another snapshot restored from tape...

Regards

Please post the output of proxmox-backup-manager version --verbose. Are there any ongoing tasks involving this backup snapshot (backups, restores, moves, ...)?
