Best practices

Roll back the primary snapshot and keep the remote snapshots as a backup.

To ensure that Remote Copy continues to operate, roll back the primary volume as follows:
1. Preserve the current state of the primary volume that you want to roll back by creating a one-time
(manual) remote snapshot of it.
2. Roll back the volume.
Before roll back, scheduled remote snapshots fail. After the primary volume is rolled back,
scheduled creation of remote copies will resume correctly.
Completed remote snapshots remain intact.

Using Remote Copy for data migration or cloning

Remote Copy allows migration of data from one application server to another without interrupting
the production application server. This capability supports a number of uses such as data mining or
content distribution.
