Byzanz is a free opensource GNOME based Command-Line utility to capture desktop recording software for linux. This should probably be the coolest command-line utility that I have seen in recent days. Byzanz records your desktop session to an animated GIF. You can record your entire screen, a single window, an arbitrary region or even follow the cursor. Given that it is only a GIF format makes it even more an interesting proposition as the file size is going to be very small.

rsnapshot is a filesystem backup utility based on rsync. Using rsnapshot, it is possible to take snapshots of your filesystems at different points in time. Using hard links, rsnapshot creates the illusion of multiple full backups, while only taking up the space of one full backup plus differences. When coupled with ssh, it is possible to take snapshots of remote filesystems as well.
