Modifying Disaster Recovery Protection for a Virtual Machine

Modify Disaster Recovery (DR) protection for a virtual machine (VM) if you need to change its Recovery Point Objective (RPO) or snapshot-retention settings.

To modify DR protection for a VM

1. On the VIRTUAL MACHINES page, click a protected VM to open its details page.
2. In the DR pane, next to the RPO and Retention summary, click the edit button.

3. In the Modify Recovery dialog box:

   1. Enter the Recovery Point Objective. The Recovery Point Objective (RPO) is the maximum acceptable period during which data might be lost from a VM. For example, if you would not want to lose more than one hour of changes, then enter 1 hour.
   2. Select the snapshot Retention setting. The DR software keeps only the specified number of snapshots. When the limit is reached, the DR software creates a new snapshot. The DR software then coalesces the oldest snapshot (that is, it merges it with the next oldest snapshot) and finally deletes the oldest snapshot.
   3. Select the check box next to Compress network transfers of snapshot data if you want to compress the snapshot data for transfers to the DR site.
4. Click Save.

The new settings are displayed in the DR pane of the VM details page. If needed, DR creates new snapshots or coalesces snapshots to comply with the updated settings.
