Failure to create backup FileNotFoundError on zigbee.db-journal

Configuration Zigbee

First off, a huge thank you to the community. I’ve been pouring over all kinds of home assistant topics over the last couple of weeks to get my system transferred from SmartThings to Home Assistant and this community has been a huge help. Everything is working and I couldn’t be happier…

I tried to create a backup and it is failing. I’m running hass 2022.2.9 on a Pi4 with a HUSBZB-1 USB zigbee/z-wave stick. I’m running the standard zha integration (NOT zigbee2mqtt).

Hi,

Did you find a solution for your backup problem - I face the same issues now running hass 2022.3.7

I managed to work around this issue. Looking at bit into things, it turns out that the -journal file is the SQLite transaction file for the zigbee database. It was written and removed quite often. The backup thinks it should be backed up as it is in the config folder, but it is removed again before it could be backed up - this makes the backup fail… The quick work around was simply to remove the zigbee usb adapter while making the backup as nothing is then changed in the zigbee database.

When I restored the backup on my new Raspberry Pi 4, everything worked right away. The strange thing is that on this new installation I never see the -journal file and backup is working again.

That explains a lot! Kind of frustrating, it should just issue a warning about the missing file rather than actually fatal. I added on a package that automatically creates backups and uploads them to my Google Drive. More often than not it is successful (no errors during backup) so I kind of forgot about this open issue. Thanks for the workaround.
