This is a very simple rsync backup script, very much inspired by rsnapshot,
but with very few dependencies (just a bash and rsync) and backups are pushed
to a server rather than pulled in.
Incremental snapshots are rotated in hourly, daily, weekly and monthly intervals.

To use, put the backup script in ~/bin
Configuration must be put in ~/.backup/config and regular rsync includes/excludes in
~/.backup/exclude

I run this with the following crontab entries:
@reboot $HOME/bin/backup > $HOME/.backup/log 2>&1
49 * * * * $HOME/bin/backup > $HOME/.backup/log 2>&1

The result will look something like this:
