5.2 Backups and recovery
One of the system administrator's important responsibilities is to perform backup in case the system is damaged or an unexpected event occurs, such as the following:
-
The disk is damaged and JP1/AJS3 does not work.
-
A jobnet is mistakenly deleted and the original settings are lost.
-
A JP1/AJS3 file is inadvertently erased by an OS operation.
These sorts of situations can occur in any system. By backing up JP1/AJS3 information in advance, you can minimize their effects. Prepare and implement a backup plan. As well as deciding on some backup procedures, you must also consider recovery methods and make sure the system can actually be restored.
This section describes how to back up and restore a system that uses JP1/AJS3. Based on the following descriptions, consider what JP1/AJS3 backup and recovery procedures to implement as part of a system-wide backup plan.
