Both InnoDB and PostgreSQL - as well as many other databases - use a technique called multi-version concurrency control (MVCC) to provide transaction isolation: transactions should not see the work of other, uncommitted transactions. MVCC means that, when a row is updated, the database stores both the old and new versions of the row.

RSYNC Server - A Remote File Transfer Protocol - Server Migration Tool

RSYNC SERVER

Remote file transfer protocol

Rsync is a linux in-built file transfer program that is similar to RCP or SCP. It includes the added feature of allowing just the differences between two sets of files on two machines to be transferred across the network.

Rsync sends un-encrypted traffic over the network, but can this can also be tunneled through SSH.

The Rsync listens on port 873.
