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


backupninja [ -h ] [ -d ] [ -n ] [ -t ] [ -f filename ] [ --run filename ]


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

- 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.


-h, --help
Show summary of options

-d, --debug
Run in debug mode, where all log messages are output to the current shell.

-f, --conffile CONF_FILE
Use CONF_FILE for the main configuration instead of /etc/backupninja.conf

-t, --test
Run in test mode, no actions are actually taken.

-n, --now
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. See backupninja.conf(5).

To preform the actual backup actions, backupninja processes each action configuration file
in /etc/backup.d according to the file's suffix. See backup.d(5).


Backupninja can be used to implement 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 /var/backups.

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 rsa -b 4096
root@srchost# ssh-copy-id -i /root/.ssh/id_dsa.pub backup@desthost

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.
