About sharing levels and sharing boundaries

When you configure sharing for a vault store group, you set a sharing level for each vault store in the group. The sharing levels determine the boundaries for single instance storage sharing in the group.

Table: Vault store sharing levels

Vault store's sharing level	Effect on sharing
Share within group	The vault store shares SIS parts with all the other vault stores in the vault store group that have this sharing level.
Share within vault store	The vault store shares SIS parts only within itself.
No sharing	Enterprise Vault does not perform single instance storage for this vault store.

A vault store group can therefore contain one or more sharing boundaries. Each sharing boundary contains one or more vault stores that share the SIS parts that result from Enterprise Vault single instance storage.

Figure: Sharing boundaries in a vault store group shows an example vault store group that contains five vault stores:

Figure: Sharing boundaries in a vault store group

Vault stores 1, 3, and 4 all have the sharing level "Share within group". These vault stores are within the same sharing boundary. Enterprise Vault shares SIS parts across the three vault stores for the items that it archives to these vault stores.
Vault store 2 has the sharing level "Share within vault store", so it has its own sharing boundary. Enterprise Vault shares SIS parts within the vault store for the items that it archives to this vault store.
Vault store 5 has the sharing level "No sharing". The vault store is not included in any sharing boundary. Enterprise Vault does not perform Enterprise Vault single instance storage on the items that it archives to this vault store.

Note that a vault store group can have only one sharing boundary that contains multiple vault stores. For example, in Figure: Sharing boundaries in a vault store group, you cannot configure two new vault stores to share SIS parts across each other and not with the existing vault stores. You can instead create the new vault stores in another vault store group.

Enterprise Vault assigns a sharing level of "Share within vault store" to new vault stores.

To change the sharing level for a vault store, run the Configure Sharing wizard on the vault store group after you have created a partition for the vault store.
