Dell PowerStore Protecting Your Data

• Replacing a protection policy that includes a replication rule with a policy without a replication rule removes replication from all the resources that are assigned with that policy.
• Replacing a protection policy that includes a replication rule with a policy that has the same replication rule enables you to reconfigure local protection without disrupting replication.
• Replacing a protection policy that includes a replication rule with a policy with a different replication rule is possible only if both policies have the same remote system configured.
  NOTE: To change assignment of a protection policy with a replication rule using a different remote system, remove the old policy before assigning a new one.
• Replacing a protection policy that includes an asynchronous replication rule with a policy that includes a synchronous replication rule may impact the performance of the volume and volume group replication sessions.

Consider the following guidelines for remote backup rules:

• Replacing a protection policy that includes a remote backup rule with a policy without a remote backup rule removes remote protection to the DD remote system.
• Replacing a protection policy that includes a remote backup rule with a policy that has the same remote backup rule causes the next backup to be a full backup (and not incremental).
• Replacing a protection policy that includes a remote backup rule with a policy with a different remote backup rule and the same remote system causes the next backup to be a full backup (and not incremental).
