And when making a calibre backup for the backup hardrive, does it include the books AND annotation files?
There are no automatic backup methods of the Kobo devices that do everything. The backup in the utilities plugin is only the database and configuration files. If you know what books are on the device, this can be used to do a restore if the books are put back into the same place.

If the want to restore exactly to a prior state, you need to backup every file on the user partition of the device.

Sorry, about the questions, but when I was trying the kobo utilities to backup the device database it went fine yesterday. But when trying a lot with this annotation backup plugins, the database backup went wrong today, said it was corrupt. The reader worked okej though, so I did like a another member, just copied back the backup from yesterday. But I feel a bit scared to use plugins again. Just want to be able to make backups of my books and annotations from the device to the computer and from the computer to the external backup harddrive, for restoration of computer or reader.
The database backup us a simple copy of the file from the device followed by a check that it is OK and then compress it. If the database is corrupt when the check is done, it means either the database is corrupt on the device, or something else was using the database when the copy was taken. If the backup us done automatically, it is sequenced with the other connection jobs, so nothing else should be using it. If you do it manually, wait until the connection jobs have finished before doing it.

If the database is corrupt, the device can keep running. It reads the database into memory and works on that with writes at appropriate times. It is only when the database is read anew that the problem are noticed. The primary time for this is a restart. What you usually see is thing like the reading status reverting to an earlier state, or old books reappearing the home page.

If the utilities plugin reports a corrupt backup, you should check the database on the device. The utilities plugin has a function to do this. If it is OK, then have a look at what was happening during the backup. If it is corrupt, then you should restore a previous backup. You can also try compressing the database. Depending on the errors, especially if they are only in the indexes, this can fix the database.
