If there is a large volume of data, do not back up all RDAREAs into a single object. If all RDAREAs are backed up into a single object, restoration of a specific RDAREA will take a long time because the RDAREAs must be loaded sequentially. Therefore, it is recommended that RDAREAs be divided into groups for making backups.
For example, when a disk error occurs, RDAREAs are restored one disk at a time, so it is recommended that the backup of a single disk be collected into a single object.
Execute the omnistat command of JP1/OmniBack II to check the status of JP1/OmniBack II during execution of the pdcopy or pdrstr command.
In this example, multiple backup generations are saved.
When the protection expiration dates are specified in this overlapping manner, the medium is reused efficiently.
Note that if permanent protection is specified, you must use JP1/OmniBack II's omnidb command to release object protection when the third and subsequent backups are made.
