Filesystem- or network error?

I'm not sure. The storage location is a network drive, with a local mount which is connected and browseable.

[mikqu]

I woke up today to a successful backup. I don't know what is happening, but hopefully it just keeps working.

[XXXBold]

Hm, there could a problem if your Network drive goes to sleep because of inactivity (Assuming you use samba?), and if you try to access it then via Vorta, it causes a timeout. Maybe it could help if you run some bash command on the drive, maybe a stat /media/K/BACKUP/BORG/Mike_laptop before starting the task, like 30s before or so.

[mikqu]

Good idea, thanks. If I just put that in the 'shell commands pre-backup' box, should that work?

[XXXBold]

I think that should do the job, yes, but I didn't test it. Try the command stat /media/K/BACKUP/BORG/Mike_laptop && sleep 10

This will run stat on the directory and wait for 10s after that. Try if that fixes your problem.

[mikqu]

The message this morning said that the command returned a non-zero code :/
Edit: Nevermind, I missed the '&&'. Just ran it manually, and it seems to have worked, thank you.
