Length of time the recovery points can go back
Notes
CDP uses a journal volume to store all the data that has changed on the production volume from the time the replication session started. The journal contains the metadata and data that enable roll back to any recovery points. The amount of space that is configured for the journal determines how far back the recovery points can go.
B
The journal contains the metadata and data that will allow rollback to any recovery points. The amount of space that is configured for the journal determines how far back the recovery points can go.
Traditional data protection technologies offer a limited number of recovery points. If
a data loss occurs, the system can be rolled back only to the last available recovery
point. CDP tracks all the changes to the production volumes and maintains
consistent point-in-time images. This makes the CDP to restore data to any
previous PIT.
