This section provides notes on synchronous high-speed backup.
Backup Processing
11.2.2.1 acmbackup (Backup command) cannot be executed until the transaction and backup volumes are in the equivalency maintenance state.
Backup Policy Setting
Backup policies can be set if the number of registered backup volumes is enough for snapshot high-speed backup operation, even if the number is not enough for synchronous high-speed backup. In this event, synchronous high-speed backup cannot be performed.
