Under the following operational conditions, the frozen update command (pddbfrz command) can be used in conjunction with backing a up user LOB RDAREA as quickly as possible:

• A method other than the database copy utility (pdcopy command) is used to back up the user LOB RDAREA.
• Backup is in units of HiRDB files.
• Updating and deletion of registered LOB data do not normally occur (the typical operation is to add LOB data).
• The user LOB RDAREA to be backed up consists of multiple HiRDB files.
