You can use System Manager to create a vault relationship from the source storage virtual machine (SVM), and to assign a vault policy to the vault relationship to create a backup vault. In the event of data loss or corruption on a system, backed-up data can be restored from the backup vault destination.
If a vault policy does not exist, you must create a vault policy or accept the default vault policy (named XDPDefault) that is automatically assigned.
For example, a destination volume in a relationship cannot be the source volume in another relationship.
