- Also, you will see another options that is Backup schedule. In this option you can create a local and remote backup.
- In Stage-1 DR policy creation, the options are almost the same as in PT and Stage-1 DRP, with the addition of one new option for Stage-2 sync: Stage-2 execution after Stage-1 sync.
- You can specify when Stage-2 should run based on your requirements, with multiple options available. In this case, we selected 'Execute after Stage-1 sync.

- Similarly, you can apply the DR policy for both stage-1 and stage-2 replication.
- You can unapply the DR policy with SWIFT. If you want to set a new operation in the DR policy from scratch, you can do so by unapplying the current policy.
- You just need to select the DR policy and click on the ‘Unapply’ button.
- Before unapplying the DR policy, it should be in an ‘Active’ or any other state except the ‘Idle’ state. You cannot unapply the DR policy when it is in the Idle state, as there will be no operation.
- When you unapply the DR policy, it will transition to the Idle state, and all operations will be wiped out. The policy will be reset to its original state.
- Before ‘Unapply’ the policy.
- After ‘Unapply’ the policy.
Pause a DR Policy with SWIFT - You can pause the DR policy by selecting a DR policy and click on ‘Pause’ button.
