WAFL Snapshots are always at the volume level. If you use the snap restore software on the controller, you can restore either the entire volume or an individual file level.

Hope this helps.

Hi Toasters

A general scene and a question related to it.

We have over 5TB of NFS datastore spread across various qtrees.

We were evaluating SMVI and came to know that it also requires snaprestore to restore the VM's

Now my question is that if e.g there was a qtree with say 50 vms on it and we'd like to snapshot only a few of them. Will this work ?

When a snap is created on the filer it will capture all the VM's thus eating up valuable disk space from the snapreserve as time goes by.

Next when we do a restore of the individual machine, it does a snap restore, however I am not sure if this only restores the individual machine or the entire stuff

Any insight/help into this will be helpful

Thanks Rahul

You can tell SMVI (v1.1) not to perform OS level disk quiecing on

It is SMVI v1.01 BTW, not 1.1 Not sure I understand this correctly, but if you are bypassing OS disk quiesce (VMWare snapshot) and doing transparent NetApp level snapshot, then why do you even need SMVI installed? Can't we just do the regular filer level snap schedule? We just upgraded to 1.01 and noticed the checkbox and were wondering about its potential use. Any ideas?
