Hi Roger,

Also a posible setup: the source is on a regular FAS system without nearstore personality and asis, but for DR you use qtree snapmirror to a nearstore. Your can turn on asis only on the destination. . You don't save space on the source, but you save a lot on the destination site.

Greetings,

Reinoud

Does this mean that the amount of replicated data is also reduced when you SM a A-SIS source volume to a filer running A-SIS as well? I hope that you mean this, because that would be great ;-)

Yes -- that's what he means! When you do a VSM of a volume with A-SIS enabled, you get corresponding bandwidth savings as the volume is transferred in its deduplicated state.
