'backup2l' generates, maintains, and restores backups on a mountable file system. The main design goals are low maintenance effort, efficiency, transparency, and robustness. In a default installation, backups are created autonomously by a cron script. It supports hierarchical differential backups with a user- specified number of levels and backups per level. This means the number of archives that must be stored only increases logarithmically with the number of differential backups since the last full backup. Hence, small incremental backups can be generated at short intervals while time- and space-heavy full backups are only run as needed.
