If you back up an entire Storage Virtual Machine (SVM) to a SnapVault backup by establishing a SnapVault relationship for each volume in the SVM, namespace and root information is not backed up. To protect namespace and root information for an SVM, you must manually create the namespace and root on the SnapVault secondary volume. When backing up LUNs to a SnapVault secondary volume, not all LUN information is replicated.
In SAN environments, the following LUN attributes are not replicated to the secondary volume:
The LUN in the SnapVault secondary volume can be in a different SVM or volume from the source LUN. Path-related metadata, such as persistent reservations, are not replicated to the SnapVault primary volume.
The Read Only state is always set to true on the destination LUN.
The NVFAIL attribute is always set to false on the destination LUN.
You can set persistent reservations for LUNs on the SnapVault secondary volume.
