All the documentation I read states that QSM compression is not supported. However, it appears to function for me. Does this mean that it works, but NA won't support issues, or is it an undocumented change?
Running OnTap 7.3.4p2 on both source and destination.

it should work. the only statement I found is in the tr-3446:
"With Data ONTAP 7.3.2, volume SnapMirror is supported without any special approvals. Qtree SnapMirror still requires NetApp approval."
It states version 7.3.2 and cannot find a newer of this doc...

Thank you. I stumbled across that same blurb, so am following up with my TGA as to what “special approval” is needed, and if this means that there are possible issues/repurcussions.

Can somebody from Netapp make any further statement on this ?
QSM compression on our WAN links would be a great benefit for us, so I'd really like to know if there's any (supported) way to use this.

Carl, The official info I received is that QSM compression works, but
it is not supported without obtaining a policy variance. I am using
quite a few volume snapmirrors and one qtree snapmirror with
compression, and they all seem to be running well. However, I have
avoided adding compression to more QSM until I obtain the PVR.
