Hi
Been researching various data synchronization techniques.. and these are
the ones I've found most interesting:
1. Google's Map/Reduce (not really data synchronization but still
interesting)
http://en.wikipedia.org/wiki/MapReduce
2. SyncML Protocol

3. CouchDB
http://couchdb.org

A slashdot article
(http://ask.slashdot.org/askslashdot/07/08/27/2359245.shtml) even
suggests rsync.
A process I'm working on involves 3 simple steps:
1. Laptop <- Pull changes since last connection.
2. Merge local changes.
3. Laptop -> Push changes back to central server.
I'm leaning towards a CouchDB approach but using a modified version of
Andre's RevOnRockets server using Valentina (mainly for the encyption
but may use sqlite and a VPN like hamachi) and a XML protocol (instead
of JSON).
Has anyone had any experience with this subject and has some useful
suggestions?
regards
alex
