Thanks! I really need to start using rsync for backup and possibly
keeping a couple of pools of data which keep in sync with each other
so any one of them can be the latest version.
A slightly different problem is solved by Apple's Time Machine. Its
the old day-week-month backup strategy that keeps earlier versions of
the data, thus making sure you don't wipe out backups with mistaken
edits/deletions within the files.
Does rsync have a similar stunt .. where you can keep several versions
of files? Maybe there's a svn/rsync stunt that would help here.
The biggest problem for me is the pathetic bandwidth we typically have
nowadays. Makes good backups and time-machine snapshots really slow
out to my hosting services and cloud storage.

Backups are done like this:
#
#/home/roberts
#
echo "Starting /home/roberts backup" >>/home/roberts/backup.log
date >>/home/roberts/backup.log
/usr/bin/rsync -vurltD --delete --exclude-from=/home/roberts/.rsync/
exclude
/home/roberts /media/usb0 >>/home/roberts
/backup.log 2>&1
echo "Completed /home/roberts backup" >>/home/roberts/backup.log
date >>/home/roberts/backup.log
where /media/usb0 is a slow but fast-enough 1 TB USB drive that powers
itself off when not being used. When that one fills up I'll get
another and
modify the script to rsync in multiple chunks.
Crude, but effective.
