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 /borgbackup.data2
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!
If you used a repokey mode, the key is stored in the repo, but you should back it up separately.
Use „borg key export“ to export the key, optionally in printable format.
Write down the passphrase. Store both at safe place(s).

# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use ‚*‘ in these fields (for ‚any‘).
#
# Notice that tasks will be started based on the cron’s system
# daemon’s notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(8)

# m h dom mon dow command
