Some of the CA using products provide backup, restore, and reorganization procedures for their CA Datacom/AD databases. You can also use standard CA Datacom/DB backup and restore procedures as described in the CA Datacom/DB DBUTLTY Reference Guide.
If the CA using product does not provide a backup and restore procedure for its databases, you should create one. Creating and restoring this backup, along with the use of the LXX and the RXX, allows your system to be fully recovered.
There are two types of backups, native and physical. The native backup uses the index to back up the data in Native Key sequence. The physical backup reads the data area with records read in the order they appear in the data area. A physical backup allows processing to continue while the database is being backed up. However, allowing maintenance during a backup can result in backup data that cannot be used without performing forward recovery.
The LOAD function of DBUTLTY performs the restore of the above two types of backups.
