Allow backends to fail/be skipped

[varac]

I'd like to always backup to my remote location, and when I'm at home I'd also like to backup a my local NAS.
It would be great if Autorestic could be configured for this in a way that it doesn't fail if the second location is not available.
Maybe a backend config like this could do it:

backends:
  remote:
    type: sftp 
    path: ...
  local: 
    type: sftp
    path: ...
    only_if:
      cmd: check_local_avail.sh
      allow_fail: true

When the script check_local_avail.sh fails, and only_if.allow_fail is set to true autorestic should (silently) succeed.
What do you think ?

Just to clearify: Autorestic will complete the backups with other backends still. But you basically want a clean exit code if it does so right?

Right, that would be perfect.
