When point-in-time recovery is enabled, a base backup is automatically performed that can to be used to restore to a specific point in time. All subsequent automatic scheduled backups will also support point-in-time recovery. Note that if you deselect this option, the cluster (and subsequent automatic backups) will be re-configured to not include support for point-in-time recovery.When point-in-time recovery is enabled, the value specified in the Backup Retention field of the Create cluster dialog determines the duration of the point-in-time recovery backup window. For example, if you specify a value of 7, the backup window will be 7 calendar days long. When the backup retention threshold is reached, the oldest base backup is removed, as well as any WAL files required to perform a recovery with that backup.Please note that you cannot perform a base backup on a cluster while the database is in recovery and not accepting connections. If you attempt to perform a base backup during recovery, the backup will fail (the failure will be noted on the Events panel of the Clusters tab). You should instead wait until the database recovery is complete to enable point-in-time recovery for the cluster.Point-in-time recovery is enabled on the Details panel of the Clusters tab. If a base backup fails, you can trigger EDB Ark to perform a base backup by disabling point-in-time recovery, and then (after waiting a few minutes) re-enable point-in-time recovery.
