Volumes and files on the source are selected for
	replication and then target server(s) and path(s) are
	selected.
	Replication software compares source and target
	files and then synchronizes the differences at a
	block level.
	On-going changes to selected files are captured for
	replication as they occur.
	Changes are transmitted continuously or per
	user-defined conditions, such as bandwidth limits
	or start/stop conditions.
	Target receives and applies the changes to target
	volumes.
	Target server monitors the source server and can
	initiate fail-over automatically or manually.
	Fail-back releases the identity of the source
	allowing original source to rejoin the network.
	The restore function returns current data back to
	original machine.
