volume 3. filer:/vol/volname - for contents of entire volume including all qtrees.
My question is, "Is there any difference between options 2 and 3, if I don't have any qtrees in any of my volumes?".
My understanding was the option 2 only backs up non-qtree data. And option 3 only back up qtree data. We use option 2 mostly as we have very few qtrees.
As I've eluded to in my question above, we don't use any qtrees in our environment. Is the above note saying that when I do a snapvault restore that it's going to restore back into a qtree and I'll have to manually copy the contents out of the qtree back into the root dir of the volume before it will be back to the way it was before the restore? I'm hoping that's not what it's saying, though it sure sounds like it.
Yes that's exactly what it is saying. In our tests we just did a mv (on a Solaris NFS mount) to put everything in the qtree back up a level which is pretty much instantaneous.
If you don't have a license or a filer on which you can experiment, I'd recommend installing the simulator for both secondary and primary Snapvault instances and trying it all out. For us, it made more sense once we could play around than just reading the docs.
