Look at Veritas Storage Replicator. Uses a client / server scheme, only
changed data is replicated and unlike FRS which replicates the whole file,
VSR only replicates the chunks which have changed. The replication schedule
can be tailored to your exact needs.
The initial sync will take a while over that small pipe; then you need to
work out what your daily change volume is and see whether you can push it
across overnight.
I don't think FRS is suitable for what you are doing here. 1 email added to
a 200MB Outlook PST file and the whole damn thing is going to replicate.
Having said that, you also need to consider restoring files in the event of
loss - with small bandwidth this might take a while - you should consider
installing a local tape drive.
