BinBackup is a tool intended to efficiently back up a directory to a set of size-limited media like CD-Rs or DVD-Rs. It's goal is to distribute the contents of a directory to a set of media while using the space available on these media as best as possible, minimizing the number of media required for a backup. To do this, BinBackup uses a bin packing algorithm to decide how to partition the contents of a directory and where to put them.
Bontmia is a network-based backup tool that saves configurable numbers of last month, week, day, hour, and minute backups. Each backup is a complete snapshot of the original directories, and only new and changed files take up space when generating snapshots because of the use of hard links. Remote access is secure by using SSH. Only changes are transferred, which makes for a fast backup.
