Hi,
I have a 2017 iMac, and I have Calibre set up to backup to a remote disk on my LAN

afp://192.168.1.2/Media/Books/Calibre/

This is also where Calibre's database is and where it imports and stores my ePub files to without issue when I drag them into the Calibre window.

When I connect my Kobo Clara HD, and it attempts to automatically backup to this location, it fails with the error

Spoiler:

A file is created with the resulting name
KoboReader-ClaraHD-N249840032138-20180909-193456_CORRUPT.sqlite
The filesize is 19.3 MB

But if I go to Kobo Utilities and choose to manually backup, it completes, and the file is called
KoboReader-ClaraHD-N249840032138-20180909-193456.sqlite
The filesize is 19.3 MB

I have changed the backup location to my local drive to save the backup file to my desktop, and it will auto backup when I connect the device. Can anyone point me in the direction of solving why auto-backup to a remote disk fails, but manually backing up to a remote disk work?
