Anyone got a way of saving disk space using diffs?

[bluep...@gmail.com]

One of the minor annoyances of using TiddlyWiki is the proliferation of backup files that results from any editing activity. Since each backup is a full copy of the wiki, backup folders can quickly become very large, requiring a pruning strategy.

Instead of doing this, it seems like there should be a much more efficient option whereby only the diff between the current version and the previous version is saved, and a process for rolling back diffs if there is a need to access an older version.

Has anyone implemented a scheme like this? I'm guessing that something like this effect can be achieved using git, but has anyone managed to do this in an automated way, without requiring a manual commit for each save?

I keep several tiddlywikis in git, and have set-up a cronjob that
commits any changes made in the last hour. The commits are automatic.

The cronjob script is just this:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
#!/bin/bash
set -e

cd /home/user/public_html/tiddlys/
git add .
git commit -am 'auto commit'
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Thank you! I'll give it a go.
