After a recovery plan has run, there are often cases where the environment must continue to be protected against failure to ensure its resilience and to meet objectives for disaster recovery. SRM offers reprotection which is an extension to recovery plan management that enables the environment at the recovery site to establish replication and protection of the environment back to the original protected site. This behavior allows users to recover the environment quickly and easily back to the original site if necessary.
It is important to note that a unassisted reprotection by SRM may not always be possible depending on the circumstances and results of the preceding recovery operation. Recovery plans run in planned migration mode are the likeliest candidates for a subsequent successful automated reprotection by SRM. Exceptions to this occur if certain failures or changes have occurred between the time the recovery plan was run and the reprotection operation was initiated. Those situations may cause the reprotection to fail. Similarly, if a recovery plan was run in disaster recovery mode, any persisting failures may cause a partial or complete failure of a reprotection of a recovery plan.
These different situations are described in the following sections.
