[Borgbackup] Prune and/or Compact finished with an error

[Adi Marvillo]

Hello everybody,
I am using the script from
https://borgbackup.readthedocs.io/en/latest/quickstart.html#automating-backups
um to automate my backups and always have this errormessage:
Keeping archive: vps48XXXXXX-2018-08-30 16:37:51.687246 Thu, 2018-08-30
16:37:51

an error

What is my principal problem with "Backup, Prune and/or Compact finished
with an errorBackup, Prune and/or Compact finished with an error"?

I was hpoing to get more information when writing --debug into the
script, but no archive is defined "borg create: error: argument ARCHIVE:
"DEBUG": No archive specified" - how to define the logging archive?

Thx adi
