[Zope] Remote Zope Backup

Hi all, Does anyone knows of a good way to backup Data.fs remotely. Currently, i have a cron job that gzip Data.fs nightly and secure copy it to a remote backup host. My packed Data.fs is over 260MB (230MB with gzip). This is just too much nightly traffic. Is there a method where i can just perform an rsync of Data.fs instead of scp? Perhaps export Data.fs into XML format, then rsync or maybe perform just an incremental backup of Data.fs some how? Does anyone have any ideas? I am running Zope 2.3.0 on Redhat 7.1. thanks, -- Mike Tran Shufflemaster Gaming Inc.
