I had to wrap my snapshot taking in a pile of scripts to track the hash of the previous snapshots of the various trees I choose to back up, or else performance went completely to hell. As is, a snapshot is way expensive - I don't do them as often as I'd like. Ideally my script would be clever enough to cache file modification times and only re-snap the changes, but that way lies madness and a loss of the fire-and-forget advantage Venti has. Not to mention how painful it is to read my past snapshots through 9P without a decent browser... I'm pretty sure apple's version won't need these kinds of voodoo from the user - the UI is likely to be pretty and functional.

(Plan9 notwithstanding :-)). Among its many features are a set of flexible, dynamic and complex snap-shotting capabilities that sound very much like the technology that could underly Apple Leopard's new back-p capabilities. This is all the more interesting in that ZFS was and has been vigorously discussed within Apple as a contender for the successor to the hybrid HFS+ OS X presently labous under. As Steve Jobs announced they were deliberately not going to announce several key Leopard technologies this could be a possibility. Just speculating, Cheers, Cy On 9 Aug 2006, at 22:52, Paul Lalonde wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > There are a couple of things I do expect to see in Apple's version > that will make life easier for me. > I had to wrap my snapshot taking in a pile of scripts to track the > hash of the previous snapshots of the various trees I choose to > back up, or else performance went completely to hell.
