If you think of the way rrdtool maintains numerical wcooley> time-series data, then the idea should seem pretty familiar. Sounds like you want the "make backups using rsync" tool that was described at Advanced PLUG a few years ago. Can't recall the name though. Generally, my rule of thumb to keep me out of trouble is that if a snapshot is triggered by a human because a logical change has happened, a version control system is appropriate. But if a snapshot is triggered by a time passing, then a version control system is *not* appropriate, and I should be looking at a backup solution instead. -- Randal L.
