Sorry that it took so long to answer - i just enjoyed my weekend ;-)
We don't own a FlexClone license and we are on ONTAP 8.1.2P4 (7-mode) with NFS Datastores only. But as i mentioned before, i also tried it on the console using snap restore ... and it wasn't really faster. So it seems like it's not a VSC-thing :(
Mit freundlichen Grüßen / Best Regards

Yep, I mentioned it, because he used VSC...
I have a feeling though, that without a FlexClone license (and ONTAP 8.1.1+) it'll work, but slow... From an unrelated part of the VSC documentation: This process uses the file level FlexClone feature of the controller. This process automatically falls back to the controller offloaded copy as needed if the fallBackToCopy parameter is set to true. I guess it does that for Restores, also.
@Markus: By now we'd really like to know, if you have a FlexClone license and what ONTAP version you're running... ;-)

Regarding licenses, it again depends on your ONTAP version:
FlexClone The FlexClone license is required in the following situations: ◦ You are using VSC to clone virtual machines. ◦ You are performing backup and restore operations in NFS environments and running a version of Data ONTAP prior to 8.1. You do not need a FlexClone license if you are performing backup and restore operations in NFS environments with one of the following versions of Data ONTAP: • Data ONTAP 8.1 operating in 7-Mode • Clustered Data ONTAP 8.1.1 or later
Hope that helps

In 8.1, we changed single file SnapRestore to use SIS clone as the underlying engine to revert the object – way faster, and makes the object immediately available as it does the clone in the background. I don’t remember if it requires a FlexClone license or just SnapRestore. Which of those licenses do you have?

Hello,
i played a bit with VMware + NetApp VSC Backup/Restore and was very surprised by the bad performance of SnapRestore on a NFS Storage.
It took SnapRestore 24 hours to restore a 1TB vmdk! Looking at the filer usage (sysstat) it looked like the filer just copied the files out of the Snapshot into the live filesystem with terrible slow 12MB/s. I always thought that SnapRestore restores in a few seconds because if just copies the pointers and not the data itself.
I tried the same again (copying out of the Snapshot), this time with ndmpcopy and got ~350GB/h, which is around 100MB/s and an expected result
Currently we don't own the SnapManager License for VSC - maybe thats the problem? A short test using the cmdline wasn't faster...
Best Regards,
Markus Schlegel
