Making backups of critical data is essential in a data processing installation. DBUTLTY provides functions to create backups of either the Directory (CXX), any database, or any data area within a database.
Make frequent backups of the Directory (CXX). If a hardware malfunction occurs during maintenance with the CXXMAINT function, you can re-create the Directory using the backup. You can make a backup of the Directory (CXX) at any time.
A backup of the Directory is the first step in moving the Directory to a different disk drive or to a disk drive of a different device type. See BACKUP CXX (Back Up Directory) and LOAD CXX (Build CXX) for details.
DBUTLTY provides several options for creating a backup of a data area. Creating a backup in Native Key sequence is the first step in reorganizing a data area. See the CA Datacom/DB Database and System Administration Guide for details on reorganizing a data area or loading a multiple table area.
For information about DBUTLTY STATUS console command support for this function, see COMM STATUS (Print Status of Multi-User Jobs).
More information about the impact of table partitioning on the BACKUP function is in The BACKUP Utility.
