SaraB works with DAR (Disk ARchive) to schedule and rotate backups on random-access media (i.e. hard drives, CDs, DVDs, Zip, or anything else except magnetic tapes). It provides a powerful rotation schedule which allows administrators to create a custom rotation that fits the needs of their network. There is no need to worry about manually rotating, labeling, and properly storing the tapes. It supports the Towers of Hanoi, Grandfather-Father-Son, or any custom backup rotation strategy. It is easy to use and highly configurable.
I(2) Drive is an online storage solution that allows personal and corporate users to manage their important information from anywhere. It provides client and server software for accessing and sharing files through a Web interface and WebDAV clients either as a hosted service or an in-house install.
prsync provides a solution for backups that is easy to configure, simple to maintain, and based on rsync. You can can specify how often to backup (daily, weekly, monthly, or yearly) and how much is needed from each of these periods. Backups from a local computer to a remote computer, remote to local, and local to local are possible. prsync will also take care of the old backups.
osarchiver (Operating System Archiver) creates CD/DVD backup images, useful for operating system disaster recovery. It features compact size, utilization of already-present operating system functionality, multiple Red Hat version compatibility, multi-volume capability, parallel compression, and hardware flexibility.
Sshbak is very simple but powerful and secure remote backup utility. It performs a fast and comprehensible daily (usually) backup of multiple machines via remote SSH connections. The result is a simple set of tar+gzip files. It supports the backup of piped program output (allowing remote backup of mysqldump or pg_dumpall results), parallel backup of different machines, and more.
The GNU Tar Autoloader Patch allows you to automate tape loading (during writing) on any autoloader that supports changing to the next tape with the "mt offline" command. This only has an effect during backup. During restore, you will still have to manually change the tape because tar hops back and forth various times. It behaves exactly as upstream except during a write operation (using the "c" flag) with multiple tapes (using the "M" flag).
