Expert User

CA VM:Backup calls the user exit with the FORDATE keyword to obtain the authorized time period (fromdate and todate) before displaying the restore screen following the Expert User Main Menu. The restore screen displayed is determined by the option the user selects from the main menu:

• If the user selects Option 1, the Select Minidisks or Directories From Which to Restore screen appears.
• If the user selects Option 2, the Select Files by Date Range or Filename screen appears.
• If the user selects Option 3, the Select Directories From Which to Restore Files screen appears.
• If the user selects Option 4, the Select Files by Date Range or File Name screen appears.

If the user changes the dates on a screen, CA VM:Backup calls the user exit with the FORDATE keyword again to check the user-selected dates. If the user is authorized to restore data backed up during the time period selected, the dates do not have to be altered. If the user is not authorized for the dates selected, VMBEXIT3 must alter the start and/or end date.

If the dates returned by VMBEXIT3 are valid, the restore request continues. If the dates are not valid, CA VM:Backup issues a message explaining that the dates returned to CA VM:Backup are invalid. This indicates a coding error in the user exit; the user cannot restore.
