is there a way to copy SVM/Volume without FlexClone or SnapMirror?

remr1n — Wed, 16 Nov 2022 02:42:15 GMT

is there a way to copy the SVM or Volume to another netapp or within its own aggregate without using FlexClone or Snapmirror?

we were planning to host the data from one netapp to another netapp using SnapMirror and delinking the source netapp for backup access. but we realized we dont have the sufficient license for snapmirror OR Flexclone...

if there is an alternative way or if there is such thing as evaluation license to use for one time only or something, that would be wonderful.

regards

Methods for copying a volume: (This implies flexclone/snapmirror)
https://docs.netapp.com/us-en/ontap/volumes/methods-copying-volume-concept.html

However, you can get around by using NDMPcopy:(You can transfer full or partial volumes, qtrees, directories, or individual files.)
https://docs.netapp.com/us-en/ontap/volumes/methods-copying-volume-concept.html

I don't know what protocols are served for the volume but NDMPcopy is a good tool as it can preserve Windows NTFS Acls and LUNs etc, in short it can copy all. I am assuming this is all between ONTAP 9 Cluster.

thank you!

if i were to use snapmirror, can i copy only the qtree or volume ifi want to? if i were to copy only the qtree, will i have to create exact same folder with the same names so the data can copy onto the destination qtree?

For Clustered Ontap: SnapMirror replications operates only at the volume level. It does not allow replication of individual qtrees or qtree-level replication.

thanks mate. this means copying the whole Volume that contains qtree and its related setting will be copied over aswell? since the "whole" volume gets snapmirrored

sorry i forgot to add that, what i mean by the reply before was that i wanted to check if i need to create the exact same qtree on the destination volume or not

No worries, you don't need to create, it will be copied as part of the volume.

thankyou!

am i understanding correctly that i have to create a new DP volume, then ill create the intercluster peer between the 2 netapps, run the snapmirror once, and if i want to use the data from the new netapp i have to modify the volume to RW from DP?

Yes, that's a correct understanding. Please make sure before the final 'update', the source (shares/cifs service) is turned off/stopped. This is to ensure destination-vol remains a true copy of the source. Finally, when you break the relationship, it will automatically make the dest-vol read/write.

To ensure a SnapMirror relationship's initial transfer is fully complete:
Run the "snapmirror show" command, check for a Relationship Status of "Idle" and a "Healthy" field indicating "true". This indicates the SnapMirror has successfully completed all outstanding transfers.
