Most of the magic in this script is handled by two other tools:

• The script assumes you are using a BTRFS filesystem for creating snapshots.
• Backups of the snapshots are made with Borg.

Ideally, backups are performed by a dedicated user account with access to user data and backups. Users, whose data is being backed up, should only have read access to the backups. This way, they (or any malware running in their account) cannot damage the backed up data.

To run the script on a regular basis, you can write a simple shell script that calls the python script, and then add this shell script to the crontab of the backup account.

For practical details on how to use the script, see the docstring at the top of the file backup.py.
