I'm having an issue with the backup, that just started a couple of days ago. I'm not sure exactly what to do about it.

Calibre version: 5.10 & 5.10.1
OS: Mac OS 11.1 Big Sur
Plugin version: 2.12.3
Device: Kobo Libra H2O

Here's the message that I get from the details of why the backup failed:

calibre, version 5.10.1 (darwin, embedded-python: True)
Failed to backup device database: Failed: Backing up Kobo device database


non-unique entry in index sqlite_autoindex_content_1
wrong # of entries in index content_bookid_index
wrong # of entries in index sqlite_autoindex_content_1

Traceback (most recent call last):
File "calibre/gui2/device.py", line 89, in run
File "calibre_plugins.koboutilities.jobs", line 200, in do_device_database_backup
raise Exception(check_result)
Exception:
non-unique entry in index sqlite_autoindex_content_1
wrong # of entries in index content_bookid_index
wrong # of entries in index sqlite_autoindex_content_1

When I run the database check, I get a similar message:

Result of running 'PRAGMA integrity_check' on database on the Kobo device:


non-unique entry in index sqlite_autoindex_content_1
wrong # of entries in index content_bookid_index
wrong # of entries in index sqlite_autoindex_content_1

Any idea of what I should do to try to figure out where the problem is?

I did have a book that had two copies on the device, but I removed it and put back one copy, and when I reconnected the Kobo, it still said that it couldn't backup the database with the same error message. (Those messages were taken after I fixed the issue of the two copies on the Kobo.)

Help, please!

Thanks.
