[SOLVED] Concern about backup on removable storage

[Valerio Pachera]

Hi all, I was considering this scenario:
- add an usb drive
- mount in /media/backup-usb
- add it also to fstab
- create a new storage in proxmox of type dir for /media/backup-usb
- schedule backup on this storage

If the external usb gets removed for any reason, the schedule backup will write in /media/backup-usb that is an empty directory on /.
This will fill-up my root filesystem.

What do you think about it?

you can set is_mountpoint to avoid this (then the backup will fail because the storage is not available)

Nice to know about that.
But I miss where to set this option.

# pvesm help add
[…]
  -is_mountpoint <boolean>   (default=no)
        Assume the directory is an externally managed mountpoint. If
        nothing is mounted the storage will be considered offline.

and also 'pvesm help set' if you want to modify an existing storage
