Have you tried rsync? You can copy whole directories omitting files
that have not changed.
rsync -auv --compress source_dir destination_server:/dest_dir
In our case we do this every two hours as a backup to a hot standby
server. It works great. I can log in to the standby server and see
sales that were made that day.
iirc it's even better than that. I don't have the source immediately to
hand, but (a) rsync was, I think, written by one of the SAMBA guys, so
they knew what they were doing, and (b) not only does it only copy files
that are changed, but if they are big it only copies the bits that
changed!
So if you're only updating the odd record in a several-megabyte file it
won't understand the U2 structure, but it'll spot that just a couple of
blocks have changed and only copy them.
Cheers,
Wol
