BACKUPNINJA - A lightweight, extensible meta-backup system
"a silent flower blossom death strike to lost data."

Backupninja allows you to coordinate system backups by dropping a few
simple configuration files into /etc/backup.d/. Most programs you might
use for making backups don’t have their own configuration file format.
Backupninja provides a centralized way to configure and coordinate many
different backup utilities.
- easy to read ini style configuration files.
- you can drop in scripts to handle new types of backups.
- backup actions can be scheduled.
- you can choose when status report emails are mailed to you (always,
on warning, on error, never).
- console-based wizard (ninjahelper) makes it easy to create backup
action configuration files.
- passwords are never sent via the command line to helper programs.
- in order to backup a db or sql database, you cannot simply copy
database files. backupninja helps you safely export the data to a
format which you can backup.
- works with Linux-Vservers.
Backup types include:
- secure, remote, incremental filesytem backup (via rdiff-backup).
incremental data is compressed. permissions are retained even with an
unpriviledged backup user.
- basic system and hardware information.
- encrypted remote backups (via duplicity).
- safe backup of MySQL, PostgreSQL, OpenLDAP, and subversion databases.
- burn CD/DVDs or create ISOs.

Use CONF_FILE for the main configuration instead of

Perform actions now, instead of when they might be scheduled.
Runs the action configuration ACTION_FILE and exits.
General settings are configured in /etc/backupninja.conf. In this file
you can set the log level and change the default directory locations.
To preform the actual backup actions, backupninja processes each action
configuration file in /etc/backup.d according to the file’s suffix. See
Backupninja can be used to impliment whatever backup strategy you
choose. It is intended, however, to be used like so:
First, databases are safely copied or exported to /var/backups. Often,
you cannot make a file backup of a database while it is in use, hence
the need to use special tools to make a safe copy or export into
Then, vital parts of the file system, including /var/backups, are
nightly pushed to a remote, off-site, hard disk (using rdiff-backup).
The local user is root, but the remote user is not privileged.
Hopefully, the remote filesystem is encrypted.
In order for this to work (ie for diff-backup to run unattended), you
must create ssh keys on the source server and copy the public key to
the remote user’s authorized keys file. For example:
root@srchost# ssh-keygen -t dsa
root@srchost# ssh-copy-id -i /root/.ssh/id_dsa.pub
Now, you should be able to ssh from user ’root’ on srchost to user
’backup’ on desthost without specifying a password. When prompted for a
password by ssh-keygen, just leave it blank by hitting return. The
"wizard" ninjahelper(1) will walk you through these steps.
