Reprotection
After a recovery plan or planned migration is executed, there are often cases where the environment must continue to be
protected against failure in order to ensure its resilience or to meet all disaster recovery objectives.
Reprotection is an SRM extension to recovery plans for use only with storage system replication. It enables the environment at
the recovery site to establish synchronized replication and protection of the original environment.
After failover of the recovery site, choosing to reprotect the environment will establish synchronization and attempt to replicate
the data between the protection groups running at the recovery site and at the previously protected primary site.
This capability to reprotect an environment ensures that environments are protected against failure even after a site recovery
scenario. It also enables automated failback to a primary site following a migration or failover.
Automated failback
You can set up an automated failback workflow to return the entire environment to the primary site from the recovery site.
The failback happens after the reprotection has ensured that data replication and synchronization are established to the original
primary site.
Automated failback runs the same workflow that was used to migrate the environment to the protected site. It ensures that the
critical systems encapsulated by the recovery plan are returned to their original environment. The workflow executes only if
reprotection is successfully completed. Failback is only available with storage system replication.
Failback ensures the following:
● All virtual machines that were initially migrated to the recovery site are moved back to the primary site.
● Environments that require that disaster recovery testing be done with live environments with genuine migrations can be
returned to their initial site.
● Simplified recovery processes enable a return to standard operations after a failure.
● Failover can be done in case of disaster or in case of planned migration.
