# Configure backup of files on the department's fs account
# Configure backup of files on the department's fs account:
# This job first copies the files to the local account 'fsaccount' in tmpfs
# and then takes a regular backup of the mirrored folder.
# See also https://borgbackup.readthedocs.io/en/stable/deployment/pull-backup.html
# which does not work due to missing permissions.

BORG_UNKNOWN_UNENCRYPTED_REPO_ACCESS_IS_OK=no (or =yes)

For “Warning: Attempting to access a previously unknown unencrypted repository”
