Backup and Restore DUMP: 42.23% done, finished in 1:01 DUMP: Change Volumes: Mount volume #2 on bugs:/dev/ rmt/0n DUMP: NEEDS ATTENTION: Is the new volume (#2) mounted on bugs:/dev/rmt/0n and ready to go?: (yes or no) Label the next cassette Vol 2, insert it into the tape drive, then enter yes. This message set is repeated for as many tapes as required to complete the backup. IMPORTANT: Proper labeling of the tape is essential to a successful recovery. As the system requests additional tape cartridges, be sure to label the tapes in the correct sequence (for example, Vol #1, Vol #2, etc.). If you insert the tapes in the wrong order during the recovery, the restoration fails. NOTE: Due to the current DocuSP licensing protection scheme, tapes can be restored only to the system from which they were backed up. In other words, tapes from one system cannot be used to clone another system. Any attempt to do this will invalidate the DocuSP license, and a full reloading of software will be required to make the system operational. If you have multiple printing systems, it is recommended that tapes be labeled with the hostname of the system to reduce the possibility of restoring to the wrong system. Testing the backup tape The following procedure enables you to check if the backup tape contains valid data. 1. Ensure that the tape drive is connected and powered on. Insert the backup tape in the tape drive. If the backup required more than one cassette, make sure that the first tape (Vol 1) is inserted. 2. Open a Terminal window and logon as root user. 3. Enter mt -f /dev/rmt/0 status to check the tape drive status. The system returns a message indicating the type of tape drive. If the system generates the error message /dev/rmt/0: no such file or directory, enter mt -f /dev/rmt/1 status. If the error message is displayed again, repeat steps 1 through 3 of the Checking the tape drive procedure, described later in this chapter. If the problem persists, call for service.

Label the next cassette Vol 2, insert it into the tape drive, then

yes
. This message set is repeated for as many tapes
as required to complete the backup.
IMPORTANT: Proper labeling of the tape is essential to a

As the system requests additional
tape cartridges, be sure to label the tapes in the correct
sequence (for example, Vol #1, Vol #2, etc.). If you insert
the tapes in the wrong order during the recovery, the
restoration fails.
NOTE:
Due to the current DocuSP licensing protection
scheme, tapes can be restored only to the system from which
they were backed up. In other words, tapes from one system
cannot be used to clone another system. Any attempt to do
this will invalidate the DocuSP license, and a full reloading of

If you have multiple printing systems, it is recommended that
tapes be labeled with the hostname of the system to reduce
the possibility of restoring to the wrong system.
Testing the backup tape
The following procedure enables you to check if the backup
tape contains valid data.
1.
Ensure that the tape drive is connected and powered on.
Insert the backup tape in the tape drive. If the backup
required more than one cassette, make sure that the first
tape (Vol 1) is inserted.
2.
Open a Terminal window and logon as
root
user.
3. Enter
mt -f /dev/rmt/0
status to check the tape drive
status. The system returns a message indicating the type
of tape drive.
If the system generates the error message
/dev/rmt/0: no
such file or directory
, enter
mt -f /dev/rmt/1 status
. If
the error message is displayed again, repeat steps 1
through 3 of the Checking the tape drive procedure,
described later in this chapter. If the problem persists, call
for service.
