Written in bash, is a very simple backup tool designed for backup a system on disks attached locally (tipically USB disks).
Based on DAR (https://sourceforge.net/projects/dar/), it suppports continously backup (using LVM snapshots and incremental backups).
Once installed there are only two configuration files:
- /etc/bkdar.conf where you define _how_ the backup is perfmored
- /etc/cron.d/bkdar where you define _when_ the backup is performed
