A full backup should not be a surprise. Follow a schedule and communicate it to your users in the WELCOME message. To prepare for a full backup | |
About 15 minutes before you want to start the backup, tell everyone to finish their work and log off. Enter the following message at the console. (Do not press Return until you have typed the entire message. Otherwise, everyone gets only part of it.) Use the TELL command. Enter:
TELL @S; BACKUP WILL BEGIN IN 15 MINUTES.
PLEASE FINISH AND LOG OFF;
INFORM YOUR QUIET NEIGHBORS Return
|
If you did accidentally enter the Return key too soon, just start all over again. Refer to chapter 5, "Performing System Functions." Prevent anyone who is not currently using the computer
from logging on. Enter: Check the new limits and jobfence by entering: The values on your console should exactly match the
ones here. If they do not, enter the above commands again.
JOBFENCE= 14; JLIMIT= 0; SLIMIT= 0
|
About 10 minutes before you plan to begin the backup, send
everyone a warning. (Remember, do not press Return until you enter the entire message.) Regardless of what users are doing, they receive the warning at their terminals. Enter:
WARN @S; BACKUP WILL BEGIN IN TEN MINUTES.
PLEASE LOG OFF. Return
|
Find out who is still using the computer by
entering: The computer responds by listing all sessions. Since you have already told people about the backup once, and warned them again just a minute ago, they should log off soon. Periodically use the SHOWJOB command to see who is still working. Another warning may be necessary. Suspend any executing jobs. First enter: If you see one or more executing jobs, suspend them before the backup begins. Use the job numbers that appear in the first column on your screen with the BREAKJOB command: Replace nnn with a job number from your screen Repeat the BREAKJOB command for each executing job in the list. When you are finished, enter: Each job should now be listed as "SUSP," or suspended. If you missed one, use the BREAKJOB command again to suspend it. When you finish the backup, you need to restart any suspended jobs.
To perform a full backup | |
Define the backup device with the FILE command.
Enter: Or use the logical device number. For example: Enter a STORE command with your options. For example, to
store all files on the system, including HFS files and directories, enter:
STORE /;*T;SHOW=OFFLINE;PROGRESS-1;DIRECTORY
|
In addition to copying all system and user files, the STORE command in
the example above prints a list of the stored files on the system printer,
notifies you of its progress every minute, and copies the file system directory. To perform a partial backup | |
Define the backup device with the FILE command.
Enter: Or use the logical device number. For example: Enter a STORE command with your options, substituting the date of the last full backup for mm/dd/yy. For example:
STORE /;*T;DATE>=6/12/90;DIRECTORY;SHOW=OFFLINE;
|
The STORE command copies all system and user files modified since the date of the last full backup, copies the file system directory, and prints a list on files stored to the system printer. |
