I’ve been having this issue with backups ever since setting up a NFS share to back up to.
The thing is, the backups do finish and work (the .tar file gets created), however the “tmp” dir that gets created while the backup is running, which stores the individual addon backups prior to being merged into the final backup never gets deleted.
If I initiate a backup in the UI of the Backups panel, it always ends with an error and says “See supervisor”.
Then there is this error (will post the full log at the bottom of this post):
OSError: [Errno 39] Directory not empty: '/data/mounts/BACKUPS/tmpf_hj_noe'
However, if I browse that directory, it is in fact empty.
I don’t think this is permissions related, since it can create and delete the tmp files… it just can’t delete that tmp directory, and always thinks there is an error.
This causes the “Home Assistant Google Drive Backup” addon (which I have since disabled from doing automatic backups for this reason) to never consider any backup to be complete. It just says “Pending…” and after 3 hours it times out and tries to create a new backup, and this just loops all day long.
I end up with an actual backup for every time it runs, but I am assuming due to that python error, it never accepts the fact that it actually completed. It is supposed to only run one time per day but I end up getting a backup every 3 hours because it apparently retries after that long if it doesn’t think the previous one worked.
(Also, from the command line if I run ha backups, the backups are not listed even though the .tar file exists and appears to be valid backup data… so the error is preventing Home Assistant from believing the backup exists)
I’ve tried fiddling with the permissions on the NFS share (on UnRAID) and it is currently:
10.1.1.0/24(sec=sys,rw,insecure,anongid=100,anonuid=99,all_squash)
The files seem to all be created with the right user/group (nobody:users).
I just can’t figure out why the backup script thinks the directory is not empty when it is.
To be clear, this error happens whether I run it manually through the UI, or by calling “hassio.backup_full” in an automation, or if it runs through the Google Drive Backup addon.
