You can create a vault store using the New Vault Store wizard.
To create a vault store
If you created a vault store group using the New Vault Store Group wizard, the New Vault Store wizard starts automatically. Go to step 5.
In the left pane of the Administration Console, expand the Enterprise Vault site hierarchy until Vault Store Groups is visible.
Expand the Vault Store Groups container to show the existing vault store groups.
Right-click the vault store group in which you want to create the vault store, and then click New > Vault Store.
The New Vault Store wizard takes you through the steps to create a vault store.
You need to provide the following information:
The name of the computer that hosts the Storage Service that the vault store is to use. The wizard requests this information only if the Enterprise Vault site contains more than one computer with a Storage Service.
The name of the vault store. The name can contain letters, numbers, and spaces.
The SQL server that is to create and manage the vault store database, and the locations for the database files.
When safety copies of items are to be removed, and how Enterprise Vault checks that partitions have been backed up.
When the vault store has been created, the New Partition wizard takes you through the steps to create a partition for the vault store.
