Configure policy target snapshot settings

You can optionally specify how archival snapshots are generated on the target cluster. You can access archival snapshots the same way that you access SnapshotIQ snapshots.

1. To create archival snapshots on the target cluster, in the Target Snapshots area, select Enable capture of snapshots on the target cluster.
2. Optional: To modify the default alias of the last snapshot that is created according to the replication policy, in the Snapshot Alias Name field, type a new alias.

   You can specify the alias name as a snapshot naming pattern. For example, the following naming pattern is valid:

   %{PolicyName}-on-%{SrcCluster}-latest

   The previous example produces names similar to the following:

   newPolicy-on-Cluster1-latest

3. Optional: To modify the snapshot naming pattern for snapshots that are created according to the replication policy, in the Snapshot Naming Pattern field, type a naming pattern. Each snapshot that is generated for this replication policy is assigned a name that is based on this pattern.

   For example, the following naming pattern is valid:

   %{PolicyName}-from-%{SrcCluster}-at-%H:%M-on-%m-%d-%Y

   The example produces names similar to the following:

   newPolicy-from-Cluster1-at-10:30-on-7-12-2012

4. Select one of the following options for how snapshots should expire:

   • Click Snapshots do not expire.

   • Click Snapshots expire after... and specify an expiration period.
