SnapMirror and NetApp storage efficiency

Dear NetApp Gurus,

 

I would like to know something more about data compresion during the SnapMirror replication.

 

In my opinion, a snapmirror source can not be compressed, but the destination volume can be compressed. I rememeber, that I read somewhere this sentences. Am I right? However, in the documentation (https://www.netapp.com/media/17229-tr4015.pdf?v=127202175503P) there is written that If the source volume is compressed, the destination volume is in a
compressed state as well. Replication of compressed volumes does not decompress the source volume
to read data for a transfer. Rather, data is replicated in a compressed state to the destination volume
.
So, it means that data compression can be enabled between the source and the destination source independently. Is it correct?

Hi @Jerry2 

 

Not sure if you've managed to get the answer you were looking for. I suggest taking a look at the first paragraph on this link - https://docs.netapp.com/us-en/ontap/data-protection/manage-storage-efficiency-task.html

 

It summarizes how efficiency and Snapmirror work quite well. 

 

Hope this helps.
