Limiting the Time Period for Catalog Searches

The time period specified in restore requests determines which catalogs CA VM:Backup searches for information about data to restore. The longer the time period, the more catalogs CA VM:Backup has to search.

In CATSEARCH restore job template files, the default time period for data to restore is 01/01/1942 00:00:00 to 12/31/2041 23:59:59. System administrators can reduce the amount of time CA VM:Backup spends searching catalogs by specifying a shorter time period on the SEARCH record through TPI or on the screens.

The LISTPD record in the VMBACKUP CONFIG file specifies the default restore selection period for all users. The CA VM:Backup system administrator can dynamically update this record to specify a short default restore selection period, limiting CA VM:Backup to searching only the more recent catalogs; however, be sure the time period calculated from the LISTPD record always includes the last full backup. If users override the default restore selection period, they can help reduce the amount of time CA VM:Backup spends searching catalogs by specifying a limited time period in restore requests.

Notes:

• For more information about specifying search time periods in restore job template files, see the restore job template SEARCH record in the Template Programming Interface Guide and "Creating or Updating Restore Job Template Files" in the Administration Guide.
• For more information about specifying search time periods for end-user restore requests, see "Managing Configuration Options" in the Administration Guide and the LISTPD Record.
