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....

debconf-copydb

DEBCONF-COPYDB(1)						      Debconf							 DEBCONF-COPYDB(1)

NAME

       debconf-copydb - copy a debconf database

SYNOPSIS

	debconf-copydb sourcedb destdb [--pattern=pattern] [--owner-pattern=pattern] [--config=Foo:bar]

DESCRIPTION

       debconf-copydb copies items from an existing debconf database into another, possibly new database. The two databases may have different
       formats; if so a conversion will automatically be done.

OPTIONS

       sourcedb
	   The name of the source database. Typically it will be defined in your debconf.conf (or .debconfrc) file.

       destdb
	   The name of the destination database. It may be defined in debconf.conf or .debconfrc, or you might define it on the command line (see
	   below).

       -p pattern, --pattern pattern
	   If this is specified, only items in sourcedb whose names match the pattern will be copied.

       --owner-pattern pattern
	   If this is specified, only items in sourcedb whose owners match the pattern will be copied.

       -c foo:bar, --config Foo:bar
	   Set option Foo to bar. This is similar to writing:

	     Foo: bar

	   In debconf.conf, except you probably want to leave off the space on the command line (or quote it: "Foo: bar"). Generally must be used
	   multiple times, to build up a full configuration stanza. While blank lines are used to separate stanzas in debconf.conf, this program
	   will assume that "Name:dbname" denotes the beginning of a new stanza.

EXAMPLES

	 debconf-copydb configdb backup

       Copy all of configdb to backup, assuming you already have the backup database defined in debconf.conf.

	 debconf-copydb configdb newdb --pattern='^slrn/' 
	       --config=Name:newdb --config=Driver:File 
	       --config=Filename:newdb.dat

       Copy slrn's data out of configdb, and into newdb. newdb is not defined in the rc file, so the --config switches set up the database on the
       fly.

	 debconf-copydb configdb stdout -c Name:stdout -c Driver:Pipe 
	       -c InFd:none --pattern='^foo/'

       Spit out all the items in the debconf database related to package foo.

	 debconf-copydb configdb pipe --config=Name:pipe 
		       --config=Driver:Pipe --config=InFd:none | 
	       ssh remotehost debconf-copydb pipe configdb 
		       --config=Name:pipe --config=Driver:Pipe

       This uses the special purpose pipe driver to copy a database to a remote system.
