[Tutor] replicating data using python /zodb advice needed

[Anthony Barker]

I need to replicate data and I want to use python which data format should
I use and how should I do it?

data formats I have looked at:
 xml
 FileSystem (zodb)
 berkeley db

replication:

I have looked at pysync which implements the rsync and xdelta algorithms
or simply calling unison (written in o'camel) or rsync.

If I write data to a file say using zodb FileSystem database and then
replicate  it using unison will only the changes go?

Any advice?
