Details of a Replication Log Volume
Each protected domain uses a single replication log for all its the VMs belonging to it.
The replication log volume consists of multiple sections (illustrated described below):
...
Replication Log Section
Keeps a record of data being replicated to the object store.
I/O coming into the DRVA is written to the Object object store.
If there is a network bottleneck the I/O will get written to the replication log.
(It acts as a temporary placeholder.)
...
Contains metadata of the VMs including garbage collection (DB).
Free Space Section
When Metadata metadata becomes full, if there is available Free Space free space in the replication log volume, the management server will automatically re-assign some of the Free Space free space to Metadatametadata.
