The replication log (RL) maintains a record of data being replicated to the object store.
The RL can become invalid in the following scenarios:
Failback after a planned failover (PFO): The current RL cannot be used because no free space would be left on it causing it to be in an invalid state. The section used by PFO can be deleted to free up space on the RL which can then be reused.
Resuming Continuous Rehydration: The existing RL can continue to be used, or it can be deleted and the freed space can be repurposed.
Explanation: The RL on the protected site will no longer be used and will become invalid after failover is complete and the DRVA on the failover site has taken ownership of the protected domain.
