Enabling SnapVault

What you need to do to enable SnapVault

You need to complete the following tasks to activate SnapVault:

Enter the license code on both the secondary storage system and the primary storage system.
Turn on the options snapvault.enable option for both the secondary storage system and the primary storage system. Setting this option enables SnapVault data transfers and Snapshot copy creation.
Turn on the NDMP service on both the secondary storage system and the primary storage system.
Set the options snapvault.access option on both the secondary storage system and the primary storage system to allow primary storage system and secondary storage system access.
- Setting this option on the SnapVault secondary storage system determines which SnapVault primary storage systems can access the secondary storage system.
- Setting this option on the SnapVault primary storage system determines which secondary storage system can access data from that primary storage system.
