SnapVault SVM-DR destination volumes

TAO1 — Mon, 12 Sep 2022 19:11:45 GMT

Hi,

Is it possible to SnapVault a SVM-DR destination volume?

SVM-DR:SourceVol ==> SVM:DestVol[SV:SourceVol] ==> SnapVault:DestVol

I can't find a definitive statement in the documentation.

Thanks

Yep, that's a SnapMirror mirror-vault cascade deployment. Here is the documentation, Fan-out and cascade data protection deployments

Also see, Ensure a common Snapshot copy in a mirror-vault deployment and About SnapMirror SVM replication

Thanks for the reply, though there is nothing in that article mentioning SVM-DR cascades. In fact, one of the articles seems to suggest that you can't cascade from a SVM-DR destination:

Have you actually configured a SVM-DR cascade or are you just working from the documentation?

Anyone form NetApp monitoring these forums?

Thanks

SVM-DR does not support cascade snapmirror so it would not work for your scenario.

Apparently I was wrong whereas SVM-DR is concerned.

@mgmt-gateway ,

If you use identity-preserve false, you can start the destination SVM (from your SVM-DR solution) and then you can use SnapMirror to vault the individual FlexVol volumes to a tertiary site or take local Snapshot copies of the individual FlexVol volumes in the SVM.

Source =======================>Dest1==================>Dest2

SVM-DR SnapMirror

(-identity preserve false) (vault)

You cannot create a cascade SVM-DR like this:

Source ==============>Dest1============>Dest2

SVM-DR ~~SVM-DR~~

@ansley_tj , thanks that's a useful option - where is that buried in the documentation please?

It is short-but-sweet:

Is it possible to enable destination SVM within SVM DR for read-only access to data? - NetApp Knowledge Base
