backup dir not unmounted after download
When using backup mount/unmount scripts, the unmount script is not run after downloading a backup.
Backups are created at night, and the mount/unmount both happen; also the mount and unmount scripts work correctly from cli. But if a client clicks to "Download" a backup, it succeeds in the mount, and the backup file is put in their /backups/ directory, but the unmount doesn't happen (remote filesystem remains mounted).
