Note
Consider the following when making decisions on the backup policy configuration and backup volume preparation:
In a backup operation using the QuickOPC function, an OPC session remains active even after the physical copy has been completed. Operators should specify the number of preservation generations so that the maximum number of OPC sessions that can be defined for the same logical unit cannot be exceeded.
Operators must prepare a backup volume in the same box as the transaction volume to be backed up.
