PROCEDURES TO BACKUP AND RESTORE THE SYSTEM
3.3 FILE SAVE PROCEDURES
The Ultimate system provides several ways of performing a complete file save of your entire disk data base. You may select the File Save option from the SYSPROG Main Menu, or use the FILE-SAVE system command (from the SYSPROG account), or log onto a special FILE-SAVE account.
Remember that a file save tape contains only the FILES
section of the disk. It does not contain the system software.
File Saving from the SYSPROG Account
File saving should only be performed by responsible system personnel. Therefore, i t is recommended that users execute file saves from the SYSPROG account only.
From the SYSPROG account, file saves may be performed by:
1. Selecting the File Save option from the Main Menu.
2. From TCL, entering a FILE-SAVE command.
File Saving from the FILE-SAVE Account
You may logon to a special FILE-SAVE account. The FILE-SAVE logon proc is a Q-pointer to the SYSPROG account's FILE-SAVE proc, and the File Save procedure is automatically invoked.
The File Save Procedure
The file save operation requires a tape (or removable CMD cartridge) to be mounted and ready to receive the files. If the tape is not ready, the system displays:
Tape unit off-line
Ensure that the File-Save tape is mounted with a write (enable) Ring, and the Tape drive is ON-LINE and at LOAD point. Hit 'RETURN' to continue.
If a write-protected tape is mounted, the system displays:
No write-ring (C)ontinue/(Q)uit?
Either mount a tape with a write ring and enter
'c'
to continue, or enter 'Q' to exit the command. A 'Q' reply causes the system to prompt:Place Write (enable) Ring on File-Save tape and try again. Hit 'RETURN' to continue.
Once a write~enabled
operation can begin.
user presses <CR> to level.

Figure A shows a sample of the messages generated by the File Save procedure. When i t has finished i t will rewind the tape and log itself OFF. Operator intervention is required only if the data to be saved exceeds one tape reel. File Saves create a complete backup of the FILES section in your disk data base (except accounts or files set up to not be saved
-"DX" files, and those requiring a special parameter - V or W - in the SAVE command).
The File Save procedure normally creates a list on the
terminal of the files i t finds as i t saves the data base. It will output error messages if i t encounters unusual or
illegal conditions but i t will attempt to continue to save data. If the terminal you run the save on is not a hard copy terminal, you may want to send the listing to your printer.
If the following options are not specified in the FILE-SAVE command, the system prompts for them:
Do you want the Console listing to go to the printer?
reply 'Y' to do so. To display the listing, reply 'N'. To exit FILE-SAVE, reply 'X'.
Enter tape block size (5008192)
-The File Save generates statistics about the saved data as a by-product. To receive a printed report, at the prompt:
Do you want to generate File statistics? (Y/N/X) reply 'Y'. To ignore the report, reply 'N'. To exit FILE-SAVE, reply 'X'.
NOTE: The FILE-SAVE command is a proc that performs a full file save, using a form of the SAVE verb:
SAVE(D,F,G,R,S,T). The SAVE and FILE-SAVE commands are detailed in the System Commands Guide.
In order to save accounts and files with the 'V' File Save option, or not save accounts and files with the
'w'
File Save option, users must execute the appropriate SAVE command (or your own user-created PROC) at the TCL level.Note that the 'R' option resets flags that have been set by update Save procedures.
Update Saves are file saves of only the updated files in the data base. See section 3.4, UPDATE SAVE PROCEDURES, for an explanation of these procedures.

3.3.1 FILE SAVING FOR MULTIPLE TAPE REELS OR DISKS
For systems with multiple tapes or removable disk cartridges, a series of prompts are associated with handling the
additional tapes/disks.
Multiple Reel Tape Procedures
When a tape reel reaches the end-of-tape (EOT) marker, the tape is automatically rewound, and a prompt message is displayed on the terminal:
Mount reel # xx:
Label
=
name time datewhere 'xx' is the two-digit hexadecimal reel number. 'Name' is the tape label. If unlabeled tapes are being used, the second line is not displayed. After the tape is mounted, loaded and ready, enter
'c'
to continue the File Save.All file save tapes are labeled. The reel number and tape label are checked for agreement with the number and label of the previous reel. If an error is detected, one of these messages will be displayed:
Incorrect Reel # Incorrect Label Reel #1 was labeled
If the reel # message is displayed, the new reel number does not match the requested reel number (or the first tape
mounted is not reel #1). Mount the correct reel and enter , C' •
If the second message is displayed, the first tape was
unlabeled and the second was labeled. Mount the correct tape and enter
Ie'.
If the third message is displayed, the first tape was labeled and the second was unlabeled. Mount the correct tape and enter
'ct.
Disk Cartridge Procedures
The disk cartridge procedures and messages are the same as the multiple reel tape procedures, above.
