Currently, only MySQL and PostgreSQL have built-in support but TKLBAM can work with other databases so long as you configure custom serialization/unserialization procedures in a hook script.

If you're using any TurnKey derived system, you don't need to install it as TKLBAM is a bundled into the TurnKey Core.

If you're using a generic Debian or Ubuntu derived system you can install it with the following shell command:

wget -O - -q \
https://raw.github.com/turnkeylinux/tklbam/master/contrib/ez-apt-install.sh \
| PACKAGE=tklbam /bin/bash

This adds the TurnKey package repository to your APT sources and uses APT to install the tklbam package and its dependencies.

Pretty much anything, though storing backups to Amazon S3 is easiest because authentication and key management are automatic. You just need to run:

tklbam-backup

But you can also backup to any storage target supported by TKLBAM's back-end Duplicity including the local filesystem, NFS, Rsync, SSH, FTP, WebDAV, Rackspace CloudFiles and even IMAP.

The local filesystem is one of the easier storage targets to use because you don't need to mess around with authentication credentials.

So assuming you want to store your backup at /mnt/otherdisk:
