SnapRestore enables you to revert a volume or file quickly to the state it was in when a particular snapshot was taken.
The filer requires a software license to enable the SnapRestore service. The license is installed on the filer at the factory per your order, so the initial setup of your filer does not involve entering license codes.
You need to enter license codes only if any of the following conditions applies:
You purchased a filer with a release earlier than Data ONTAP 4.0 software and you are upgrading it.
You want to enable SnapRestore, which was not previously licensed for your filer.
You reinstalled the file system on your filer.
You are provided with the appropriate license codes when the software upgrade kit is shipped or when you are given instructions for obtaining the software upgrade over the Internet.
