hmm just got 3 more soft lookups in a few hours (2/3 hours I think) ;) my script (attached in case you want to try it) for backups basically do: rm -rf hourly.11 mv hourly.10 hourly.11 ... mv hourly.1 hourly.2 mv hourly.0 hourly.1 cp -al hourly.1 hourly.0
rsync [various options] /home/ hourly.0/
the size of the base backup being about 37Go which is incrementally
rsync-ed thanks to hard links on a 500Go raid6 array.
another backups scripts just rsync some box over ssh once a day ...
tell me if I can provide more infos that could help you ...
Cheers,
Mik
