The only Mirroring Controller resource is the Mirroring Controller management directory, which stores the files that define the Mirroring Controller behavior, and the temporary files that are created when Mirroring Controller is active.
Note
Do not create the Mirroring Controller management directory in a directory managed by Symfoware Server, otherwise it may be deleted by mistake or may cause unexpected problems when Symfoware Server recovery is performed (such as old version of files being restored).
Refer to "Preparing Directories for Resource Deployment" in the Installation and Setup Guide for Server for information on the directories managed by Symfoware Server.
The backup methods described in "Backing Up the Database" in the Operation Guide cannot be used to back up the Mirroring Controller resources. Therefore, users must obtain their own backup of Mirroring Controller resources, in addition to Symfoware Server server resources.
The image below shows the configuration when backing up Mirroring Controller resources
The content on the primary server will be backed up. You cannot tell which server is the primary server to be backed up, because switching and failback may be performed between the servers. It is also impossible to tell which server is to be restored using the backed up data. Accordingly, ensure that you create a backup of each server when it is working as the primary server.
