I've looking into the possibility of using rsync for mirroring where we are currently using iOra.
It looks like iOra has two main advantages over rsync: 1) can calculate deltas across multiple files (i.e., blocks common to two files will only appear once in the delta) 2) can de-couple delta calculation and application (creates deltas offline) I'm pretty sure I can emulate (1) by simply making a tarball of the target directory and having rsync work off that file, but it may already handle that situation. De-coupling as in (2) above is the tricky one. It seems that one way to get this behavior is to modify rsync so that where data would normally be transferred to the client, the same data could be output to a file. Likewise, the client could be modified to take its commands from the file instead of from the server. I don't know how feasible this would be...any ideas?
