Pruning backups
If you're scripting daily, weekly, or monthly backups, you'll probably want to prune old backups.
The command below will keep one backup from today, one backup from last week, and one backup from one month.
borg prune --keep-daily 1 --keep-weekly 1 --keep-monthly 1 remote:~/my_backup
