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 "-suspend"operand specified.
In synchronous high-speed backup, executing the backup command without "-suspend" operand specified releases the EC session. Executing it with "-suspend" operand specified suspends the EC session instead of releasing it.
Ordinary backup operations and backup operations with the suspend specification are shown below.
