For synchronous high-speed backup using the Suspend/Resume function, start synchronous processing. Then, when the copy status of both the transaction volume and backup volume attain equivalency maintenance status, execute swstbackup (Backup execution command) with the suspend specification (using -suspend option).
In synchronous high-speed backup, executing the backup command without the suspend specification releases the EC session. Executing it with the suspend specification suspends the EC session instead of releasing it.
Ordinary backup operations and backup operations with the suspend specification are shown below.
