Deja Dup doesn't hunderstand zfs quotas

[TOP]

Backups are being stored using and external usb drive with the zfs filesystem. There is a quota set on the backup partition. When deja-dup fills the partition to it's quota it simply stops backing up instead of deleting the oldest backups to make room for new backups. Setting the quota higher will allow deja-dup to continue, but the this is not a desired behavior, after all, what are quotas for but to limit disk usage.

Deja-dup does not seem to recognize a zfs quota limit as a full disk.

Oh that’s interesting yes. I’ll have to see how to get the quota info from gvfs and apply it to our calculations. Thank you for the report!

I also uninstalled the vanilla version of deja-dup that came with 18.04 and
installed the snap with the latest. Will see in a few days whether anything
is different.
