Backupninja lets you drop simple config files in /etc/backup.d to coordinate system backups. Backupninja is a master of many arts, including incremental remote filesystem backup, and MySQL backup. By creating simple drop-in handler scripts, backupninja can learn new skills. Backupninja is a silent flower blossom death strike to lost data.

In addition to backing up regular files, Backupninja has handlers to ease backing up: Maildir, MySQL, PostgreSQL, SVN, Trac, hardware and system information, as well as the output from custom shell scripts.
