Use the Backup Table of Contents Readback function to verify that a backup of a file was successful. When a file backup is successful, the system updates the file's backup time and date in the tape's table of contents.
After you load the backup tape in the drive, the function reads back the table of contents. You can then check the time and date of the last backup for the file in question.
To verify a file backup on tape:
From the System > System Programming > System Maintenance menu, select Backup Table of Contents Readback to display the CPIO Backup Table of Contents screen.
Note: If prompted, log on to the character-based system.
The system populates the Backup Device field with the backup device name specified in the Unix Backup Device Path Name control maintenance record. For example, /dev/
To read from a drive other than the default drive, you must enter that drive name.
Insert the backup tape into the drive and press Enter.
Note: If there is no tape in the drive when you press Enter, the following message displays: Cannot find or open the file.
The program reads the tape. File information scrolls onto the screen. If a file is listed, it was backed up.
The following six columns of information display:
Size of file.
Owner of file.
Bytes of data in file.
Date and time the file was last updated.
Directory.
File name.
Scroll through the displayed screen to locate the name of the file to check.
When you locate the file name, look in the fourth column to find the date and time you made the last backup.
When you are finished, enter Q following the colon on the screen to quit.
It will take a moment to stop the process. The tape rewinds and must finish before you can exit the screen.
When the backup tape is rewound, remove it from the tape drive.
