N-way configuration In most cases D2D VTL and D2D NAS replication is the same, the only significant configuration difference being that VTL replication allows multiple source libraries to replicate into a single target library, NAS mappings however are 1:1, one replication target share may only receive data from a single replication source share. In both cases replication sources libraries or shares may only replicate into a single target. However with VTL replication a subset of the cartridges within a library may be configured for replication whereas a share may only be replicated in its entirety. 51

N-way configuration
In most cases D2D VTL and D2D NAS replication is the same, the only significant configuration difference being
that VTL replication allows multiple source libraries to replicate into a single target library, NAS mappings
however are 1:1, one replication target share may only receive data from a single replication source share. In
both cases replication sources libraries or shares may only replicate into a single target. However with VTL
replication a subset of the cartridges within a library may be configured for replication whereas a share may
only be replicated in its entirety.
