Describe the problem you're observing.
The backup fails with "self test failed This is a bug either in Borg or in the package / distribution you use.".
Can you reproduce the problem? If so, describe how. If not, describe troubleshooting steps you took before opening the issue.
No. But, it is the third time it occurs on this server (18th of August 2020, 25th of August 2020 and 14th of September 2020).
Backups are done every hour (24 times per day), so it is very rare.
