Backup error

[apgp]

When backup finises it gives this error message:
Fallo con un error desconocido
Traceback (innermost last):
File "/usr/bin/duplicity", line 92, in <module>

Can it prevent restoring the copy? How I can solve that? Thank you

I don't use duplicity. There are a number of reasons for that non-choice, but mainly because monthly "FULL" backups are still mandatory which most people seem to miss in their backup routine.

So, my first question is are you doing monthly full backups as required by all duplicity/deja dup/duplicati tools?

I make a full backup every week.

I am using the Ubuntu 22.04 backup app.
