The following figure shows the location for storing information backed up by using the ajsbackup command or JP1/AJS3 - View.
|
This figure is explained below.
- Backup information directory
-
This directory stores backup information. You can specify any directory name using a JP1/AJS3 environment setting parameter.
- Backup box
-
A backup box is a directory used to store backup files. You can specify any directory name when backing up files.
In Windows, you cannot use CON, PRN, AUX, CLOCK$, NUL, COMm (m: integer from 1 to 9), and LPTn (n: integer from 1 to 9) for the directory name of a backup box. You can collect added and changed units in a backup box. By creating a backup box for each application, for example, you can manage additions and changes for each application.
Each backup box can contain a maximum of 1,024 backup files.
Backed-up units can be restored only on the server on which they resided when backed up.
If you want to restore units onto a different server, two steps are required. First, on the server where the units were backed up, use the ajsprint command to output the unit definition. Next, on the other server, use the ajsdefine command to restore the units.
- Backup file
-
A backup file contains the units output by executing the ajsprint command with the -a option specified. A four-digit number from 0001 to 1024 is automatically assigned as a file name.
- Backup information management file
-
A file for managing information about the backup files stored in a backup box.
To view the names of the backup files and units in a backup box, use the ajsrestore command.
