- When standalone BACKUP finishes booting, it displays an
identification message followed by the dollar sign prompt ($):
%BACKUP-I-IDENT, standalone BACKUP V7.3; the date is 19-MAY-2000 15:50
$
|
- Remove the tape cartridge containing standalone BACKUP from the
tape cartridge drive.
To make a backup copy of the system disk, see
Section 11.17.3.
To restore the system disk, see Section 11.17.4.
11.17.3 Backing Up the System Disk to Tape
When backing up your system disk, you must understand the functions of
the /IMAGE and /PHYSICAL qualifiers to the BACKUP command before using
standalone BACKUP:
Qualifier |
Function |
/IMAGE
|
Lets you create a functionally equivalent copy of the entire system
disk. When restored, files from an image backup are placed contiguously
on the system disk, eliminating disk fragmentation.
|
/PHYSICAL
|
Copies, saves, restores, or compares the entire system disk in terms of
logical blocks, ignoring any file structure.
|
For a complete description of the Backup utility qualifiers, refer to
the OpenVMS System Management Utilities Reference Manual.
How to Perform This Task
To perform an image backup of the system disk to tape, use the
following procedure:
- Obtain blank tape cartridges or magnetic tapes that you can use for
the backup operation.
- Write-enable the tape. To write-enable a tape cartridge, slide the
write-protect switch away from the tape cartridge label. To
write-enable a tape, insert a write-enable ring in the back of the tape
reel.
- Insert a tape into the tape drive.
- Determine the device name of the system disk you are backing up.
(See Section 8.2 for information about determining the names of your
devices.) To display the device name of the system disk you are booted
from, enter the DCL command SHOW LOGICAL SYS$SYSDEVICE.
- Depending on your configuration, either boot standalone BACKUP or
start the menu system:
- If you have access to the OpenVMS Alpha or VAX operating system
distribution compact disc, start the menu sytem described in
Section 11.17.1.
- If you do not have access to the OpenVMS VAX operating system
distribution compact disc, boot standalone BACKUP as described in
either Section 11.17.2.2 or Section 11.17.2.4.
- Enter the BACKUP command in the following format:
BACKUP/IMAGE/VERIFY input-specifier: output-specifier:saveset.BCK/REWIND/LABEL=label
|
where:
- input-specifier is the device name of the system disk.
- output-specifier is the device name of the drive that you
want to hold the backup copy.
- saveset.BCK is the name of the save set. The name should
reflect the contents of the tape (for example, OCT_31_2000.BCK) and
cannot exceed 17 characters in length.
- label is the volume label of the tape in the drive. If the
tape has been initialized already, use the same volume label that was
assigned by the INITIALIZE command.
For example:
$ BACKUP/IMAGE/VERIFY DUA1: MUA0:DEC_31_BACKUP.BCK/REWIND/LABEL=WKY101
|
- The following message indicates that BACKUP has transferred the
files and is verifying the accuracy of the backup copy:
%BACKUP-I-STARTVERIFY, starting verification pass
|
- If your system disk contains more data than a single tape cartridge
or magnetic tape can store, the procedure displays the following
messages and prompt:
%BACKUP-I-RESUME, Resuming operation on volume 2
%BACKUP-I-READYWRITE, Mount volume 2 on _MUA0: for writing
Enter "YES" when ready.
|
If you do not receive these messages, see step 9. If you do receive
these messages, perform the following steps:
- Remove the backup tape from the drive.
- Label it COMPLETE SYSTEM BACKUP and include the date and the number
of the tape in the sequence.
- Write-protect the backup tape.
- Write-enable another scratch tape and insert it into the drive.
- When you are ready to continue, enter Y (for YES) and press Return.
- The procedure displays the following message, which indicates that
it has transferred the files and is verifying the accuracy of the
backup copy:
%BACKUP-I-STARTVERIFY, starting verification pass
|
Each time the procedure displays a mount request, follow steps a
through e.
- If you are using standalone BACKUP, when the backup is finished,
the system displays the following message:
%BACKUP-I-PROCDONE, Operation completed. Processing finished at 19-MAY-2000
15:30. If you do not want to perform another standalone BACKUP operation,
use the console to halt the system.
If you do want to perform another standalone BACKUP operation,
ensure the standalone application volume is online and ready.
Enter "YES" to continue:
|
Continue with step 11.
- If you are using the menu system, the DCL prompt appears after the
backup is finished. Log out and choose the Shutdown option from the
menu.
- Remove the backup tape from the drive. Label it COMPLETE SYSTEM
BACKUP, number it (if you used more than one cartridge), and include
the date.
- Write-protect the tape cartridge or magnetic tape.
- Halt the system.
- Reboot the system.
- Store the backup tapes in a safe place.
11.17.4 Restoring the System Disk from Tape
If a problem occurs that renders your system disk unbootable, you can
restore the system disk from your backup copy.
How to Perform This Task
To restore the system disk from tape, use the following procedure.
Note
The BACKUP restore operation creates a system disk that includes a set
of volume parameters provided by Compaq, including a cluster size (disk
access scheme). You can change most volume parameters later with the
SET VOLUME command. For cluster-mounted volumes, changes occur to the
nodes on which the SET VOLUME command is issued.
To change the cluster size, back up the system disk to a disk that has
been previously initialized with the cluster size that you want. For
more information about initializing a disk, see Section 9.3. For
more information about the BACKUP command qualifiers, refer to the
OpenVMS System Management Utilities Reference Manual.
|
- Depending on your configuration, either boot standalone BACKUP or
start the menu system:
- If you have access to the OpenVMS Alpha or VAX operating system
distribution compact disc, start the menu system described in
Section 11.17.1.
- If you do not have access to the OpenVMS VAX Version operating
system distribution compact disc, boot standalone BACKUP as described
in either Section 11.17.2.2 or Section 11.17.2.4.
- Determine the device name of the system disk you want to restore.
(See Section 8.2 for information about determining the names of your
devices.)
- Insert the first tape of the complete system disk backup into the
drive. Make sure the tape is write-protected.
- Enter the BACKUP command in the following format:
BACKUP/IMAGE/VERIFY input-specifier:saveset.BCK/REWIND output-specifier:
|
where:
- input-specifier is the device name of the drive that holds
the backup copy.
- saveset.BCK is the name of the save set.
- output-specifier is the device name of the system disk
that you are restoring.
For example:
$ BACKUP/IMAGE/VERIFY MUA0:DEC_31_BACKUP.BCK/REWIND DUA0:
|
- The procedure displays the following message:
%BACKUP-I-STARTVERIFY, starting verification pass
|
- If your system disk contained more data than one tape could store,
you receive the following messages and prompt:
%BACKUP-I-RESUME, Resuming operation on volume 2
%BACKUP-I-READYREAD, Mount volume 2 on MUA0: for reading
Enter "YES" when ready.
|
If you do not receive these messages, see step 7. If you do receive
these messages, perform the following steps:
- Remove the backup tape from the drive.
- Insert the next backup tape into the drive.
- When you are ready to continue, enter Y (for YES) and press Return.
- The procedure displays the following message:
%BACKUP-I-STARTVERIFY, starting verification pass
|
Each time the procedure displays a mount request, follow steps a
through c.
- If you are using standalone BACKUP, when the restore is finished
the system displays the following message:
%BACKUP-I-PROCDONE, Operation completed. Processing finished at 19-MAY-2000
15:30. If you do not want to perform another standalone BACKUP operation,
use the console to halt the system.
If you do want to perform another standalone BACKUP operation,
ensure the standalone application volume is online and ready.
Enter "YES" to continue:
|
Continue with step 9.
- If you are using the menu system, the DCL prompt appears after the
restore is finished. Log out and choose the shutdown option from the
menu.
- Remove the last backup tape from the drive.
- Halt the system.
- Reboot the system.
- Store the backup tapes in a safe place.
11.17.5 Backing Up the System Disk to a Disk
To eliminate disk fragmentation, perform a disk-to-disk image backup
without using the /SAVE_SET qualifier. This creates a functionally
equivalent copy of the entire system disk, on which files are stored
contiguously.
Note
This procedure initializes the output disk, effectively erasing the
files on the disk.
|
How to Perform This Task
To perform a disk-to-disk image backup, use the following procedure:
- Obtain a disk with enough storage capacity to use for the backup.
Make sure the disk does not contain files you need, because standalone
BACKUP initializes the output disk.
- Determine the device name of the system disk you are backing up.
(See Section 8.2 for information about determining the names of your
devices.) To display the device name of the system disk you are booted
from, enter the DCL command SHOW LOGICAL SYS$SYSDEVICE.
- Depending on your configuration, either boot standalone BACKUP or
start the menu system:
- If you have access to the OpenVMS Alpha or VAX operating system
distribution compact disc, start the menu system described in
Section 11.17.1.
- If you do not have access to the OpenVMS VAX operating system
distribution compact disc, boot standalone BACKUP as described in
either Section 11.17.2.2 or Section 11.17.2.4.
- Enter the BACKUP command in the following format:
BACKUP/IMAGE/VERIFY input-specifier: output-specifier:
|
where:
- input-specifier is the device name of the system disk.
- output-specifier is the device name of the drive that you
want to hold the backup copy.
For example:
$ BACKUP/IMAGE/VERIFY DUA0: DUA1:
|
- BACKUP displays the following message, which indicates that it has
transferred the files and is verifying the accuracy of the backup copy:
%BACKUP-I-STARTVERIFY, starting verification pass
|
- If you are using standalone BACKUP, when the backup is finished the
system displays the following message:
%BACKUP-I-PROCDONE, Operation completed. Processing finished at 19-MAY-2000
15:30. If you do not want to perform another standalone BACKUP operation,
use the console to halt the system.
If you do want to perform another standalone BACKUP operation,
ensure the standalone application volume is online and ready.
Enter "YES" to continue:
|
Continue with step 8.
- If you are using the menu system, the DCL prompt appears after the
backup is finished. Log out and choose the shutdown option from the
menu.
- You can use the backup output disk as the system disk. Files are
stored contiguously on the output disk, eliminating disk fragmentation.
- Store the original system disk.
- Halt the system.
- Reboot the system using the newly created system disk.
11.17.6 Using InfoServer Tapes to Back Up and Restore System Disks
On VAX systems, you can back up the system disk to an InfoServer tape
and restore the system disk from an InfoServer tape.
How to Perform This Task
- Boot the system from the SYS1 directory using the current version
of the OpenVMS CD-ROM, which can be in a reader on the
InfoServer or on a local drive.
Note
The boot command you use for your computer depends on the type of
system you have. For more information about booting your system, refer
to the installation and operations supplement for your computer.
|
- Choose option 1 from the menu system.
- At the prompt, you can perform the backup of your system disks.
Example 11-1 shows the procedure for backing up a system disk to an
InfoServer tape.
