You mean venti ? Actually: that's an idea I'm thinking about for quite a while :) But venti is yet lacking delete operations and differential compression. The first is unproblematic (even it would require rewriting the log areas in some ways to reclaim space), but for differential compression, the venti store would have to know a lot about the object's internal structure. I'm doing some bit reasearch in the area of distributed content-addressed objects stores , designing an superstore called "Nebulon" [1] with things like strong encryption and on-demand fetching/syncing. But getting git into it seems to be a bit tricky, at least the hashes would change ... cu [1] http://www.metux.de/index.php/de/nebulon-storage-cloud.html -- ---------------------------------------------------------------------- Enrico Weigelt, metux IT service -- http://www.metux.de/ phone: +49 36207 519931 email: weigelt@metux.de mobile: +49 151 27565287 icq: 210169427 skype: nekrad666 ---------------------------------------------------------------------- Embedded-Linux / Portierung / Opensource-QM / Verteilte Systeme ----------------------------------------------------------------------
