Notes about synchronous high-speed backup using the Suspend/Resume function and backup operation design are provided below, as well as information related to backup management operation design (see "4.2 Operation Design").
Transaction volume
Register the backup source device used for storing transaction data as the transaction volume.
Backup volume
Register the backup destination device in which transaction volume data is saved as the backup volume.
When the backup command with -suspend specified is executed, the EC session between the transaction volume and backup volume is maintained in a Suspended state. In this Suspend state, the backup volume cannot be used as the backup destination of another transaction volume.
Point
In the backup process that uses the Suspend/Resume function, each transaction volume requires as many backup volumes as the saved generation number + 1.
