# By default repositories initialized with this version will produce security
#errors if written to with an older version (up to and including Borg 1.0.8).
#
# If you want to use these older versions, you can disable the check by running:
#borg upgrade --disable-tam /srv
#
# See https://borgbackup.readthedocs.io/en/stable/changes.html#pre-1-0-9-manifest-spoofing-vulnerability for details about the security implications.
#
# IMPORTANT: you will need both KEY AND PASSPHRASE to access this repo!
# Use "borg key export" to export the key, optionally in printable format.
# Write down the passphrase. Store both at safe place(s).
