I have approx 15GB of user data stored at site A that I would like replicated real time to site B.
Site A (office location) has a 4meg ADSL connection with 0.5 meg upstream and site B is at a data centre with 100meg connection.
I have already done a manual copy of files from A to B so changes from now on should be relatively small.
Remote users will VPN into site B to retrieve files as connection to site A is too slow.
How can I best automate replication of files between sites in realtime? I have seen a multitude of spftware programs claiming to do the job but would welcome a recommendation.
