Resumable Replication

When a scheduled or continuous replication update is interrupted due to a network failure, system outage, or operator action, data transfer automatically resumes from the point of interruption. This feature is available with OS8.7.0 or later, and must be installed on the source and replication target. For example, if a scheduled replication transfers 100 bytes of data before a failure occurs, the next replication update resumes data transfer at byte 101. The estimated data size, shown in the replication progress monitor, includes data to be sent as part of both actions.

If a failure occurs during a manual replication update, the update is not automatically retried, however the data transfer will resume from the point of interruption with the next replication update.
