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.
rsync-mirror is used to backup local directories to another location on the local machine or to a remote machine. As the name suggests, it uses rsync for data transfer so it should be pretty efficient. It does not support any nifty backup features like incremental backups; all it does is mirror a directory to another location. To ease the task of creating backups, rsync-mirror takes care of managing the destination site of the backup. In case the target path needs to be mounted, rsync-mirror does so before backup and unmounts it afterwards.
