Sure, that’s from the VSC docs. My previous comments were in regards to SFSR in general.

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

Hi Markus
What version of ONTAP is this? 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?

Subject: SnapRestore very slow
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
