Copy of HP-UX from MO disc
This is my newbi question. I have HP-UX on a MO drive, need to backup that MO in case of damaging the original. Therefor I need a copy on server and be able to put that copy onto a blank MO to recreate a working bootable disc. This what I did.
First I tried to make a copy with dd

dd if=/dev/dsk/c1t0d0 bs=1048576 count=450 of=backup.copy
The data on disc is about 300Mb so 450 would be enough i thought. Not working, som of the files were corrupted. Tried without the count and just backed up the whole MO, same thing. Tried cat /dev/dsk/c1t0d0 >backup.copy, same thing. But on the latter I came a bit futher, almost ½ of the install sequence before it found a corruped filed and quit. Is there a better way?
I would prefer to specify the filesize, cause it seems unnessesary tu put about 1.3Gb file on server when the files on MO is about 300Mb. Can this be fixed?
Hope someone understand my newbi question....

bdb.db0

BDB.DB0(5)							AFS File Reference							BDB.DB0(5)

NAME

       bdb.DB0, bdb.DBSYS1 - Contain the Backup Database and associated log

DESCRIPTION

       The bdb.DB0 file contains the Backup Database, which records configuration information used by the AFS Backup System along with cross-
       indexed records of the tapes created and volumes dumped using the Backup System commands.

       The bdb.DBSYS1 file is a log file in which the Backup Server (buserver process) logs each database operation before performing it. When an
       operation is interrupted, the Backup Server replays the log to complete the operation.

       Both files are in binary format and reside in the /var/lib/openafs/db directory on each database server machine that runs the Backup
       Server.	When the Backup Server starts or restarts on a given machine, it establishes a connection with its peers and verifies that its
       copy of the bdb.DB0 file matches the copy on the other database server machines. If not, the Backup Servers use AFS's distributed database
       technology, Ubik, to distribute to all of the machines the copy of the database with the highest version number.

       Use the commands in the backup suite to administer the Backup Database. It is advisable to create a backup copy of the bdb.DB0 file on tape
       on a regular basis, using the UNIX tar command or another local disk backup utility.
