Does block level replication require local disk access (Block lev el) or can it work with a network share too

[Antony Parkin]

Could i run rsync on a linux server which is connected to a network share
(NAS) and replicate the diffs of the files residing on the network share? or
does this functionality require block level access i.e Local disk or SAN?
 
Many thanks,
Antony.
