This section provides notes on synchronous high-speed backup.
The processing of the backup
The swstbackup (Backup execution command) cannot be executed until the transaction and backup volumes are in an equivalent state.
Backup policy settings
A backup policy can still be set up if the number of registered volumes is enough for snapshot type high-speed backup, even if the number is not enough for synchronous high-speed backup. In this case, synchronous high-speed backup cannot be performed.
The error: loss of delay write-in data
When backup synchronous processing starts, the error "loss of delay write-in data" may occur. If the volume which has generated the error is performing backup synchronous processing, you can ignore the error, since the problem is not in the adjustment of backup data.
