What you really want is a copy-on-write tree, or a simpe cp. Or are you that short on space that you need compression?
Speaking of which, I know copy-on-write files are planned. What about whole trees?
But, short of that, you can always do a poor man's copy-on-write with "cp -al" or "cp -as", assuming you remember to copy when you write...

I just keep a -mm patch around and the original vanilla tarball, but to each his own.

I back up with rsync, actually.
Speaking of backup, that's another nice place for a plugin. Imagine a dump that didn't have to be of the entire FS, but rather an arbitrary tree... That might be a nice new archive format. I know Apple already uses something like this for their dmg packages. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org
