Snapmirroring from a snapmirror destination

johnhuber

Has anyone  used a snapmirror destination as the source for another snapmirror going to another destination.   An example would be Volume A is being snapmirrored from Site A to Site B.  Volume A on Site B is then being snapmirrored to Site C.  This is being done because the bandwidth at Site A  is limited and we do not want to run a Snapmirror from Site A  to Site B  and Site A to Site C.    I have not found to much information on this.  The snapmirrors use the same volume signatures with different time stamps.  Normally you would have 2 different volume signatures snapmirroring from a single site to 2 separate locations.  It works but it makes me uncomfortable doing it.

This can be done through the CLI.  It can't be done through the QUI.  Also only 2 hops as you have described is supported.  So the easiest way would be to snapmirror A to B through system manager.  Then use the snapmirror create command from location C.

Completely supported. The technical term is cascading SnapMirror.
