dirvish takes a bit of setup, but it can be the basis for a great
backup solution, IMHO. I use it for backing up my home systems and
also at work. I added a bit of scripting to create symlinks so that
the past state of my filesystems are available on line.

Here is a directory listing of my /backup directory.

My full fs hierarchy exists under each date-named symlink as of that
date. If a file didn't change between snapshots, it shared between the
snapshots via hard links. It has come in handy when I have accidentally
removed or overwritten a file.
