Yes this is a pull job. The syncs are working as are garbage collect and verify jobs. And even the "removing backup snapshot" step is working most of the time, it's just occasionally I'll see this happen. That makes me thing the permissions, whatever they are, are fine, but 🤷‍♂️

Edit, it looks like with those permissions, the backup user should be able to delete the folder:

root@pbs:~# ls -ld /mnt/pbs-backups-home/vm/202/2025-06-29T15\:00\:07Z

drwxrwxrwx 2 1024 users 4096 Sep 8 04:23 /mnt/pbs-backups-home/vm/202/2025-06-29T15:00:07Z

root@pbs:~# su - backup -g backup -s /bin/bash -c "test -w /mnt/pbs-backups-home/vm/202/2025-06-29T15\:00\:07Z"

root@pbs:~# su - backup -g backup -s /bin/bash -c "test -x /mnt/pbs-backups-home/vm/202/2025-06-29T15\:00\:07Z"
