Network how do I make a backup?

Hi all,

I am having problems trying to get a backup of the whole machine using two tapes. This is because it doesn't fit onto one tape. I am using a machine with HP-UX version B.10.20.

I'll try and sketch the problem

I have these file systems (output of bdf):
/
/stand
/var
/volA
/volB
/tmp
/usr

I want to put
/
/stand
/tmp
onto one tape and
/var
/volA
/volB
/usr
onto another tape

Backing up all file systems except the root (/) goes fine, but if I back up the root filesystem it grabs the rest also.

So, I suppose my question is; How do I backup the root file system WITHOUT grabbing the other mounted file systems?

I have also read the man pages on tar and cpio but still can't get it to work the way I would like it to.

thanks,
Ivo

AMVERIFY(8)						      System Manager's Manual						       AMVERIFY(8)

NAME
amverify - check an Amanda tape for errors SYNOPSIS
amverify config [ slot [ runtapes ] ] DESCRIPTION
Amverify reads an Amanda format tape and makes sure each backup image can be processed by amrestore and, if possible, the appropriate restore program (e.g. tar). Amverify runs amrestore on each file of the tape and pipes the output to a restore program (if available) with an option to create a cata- logue of the backup. The catalogue itself is discarded. Only the success or failure of the operation itself is reported. If the backup image cannot be processed by the restore program, e.g. if it was written on a different operating system, the image is sent through dd to /dev/null. This still determines if the tape is readable, but does not do any internal consistency check on the image. If config is set up to use a tape changer, the slot argument may be used to choose the first tape to process. Otherwise, the current slot is used. The runtapes configuration parameter determines how many tapes are processed unless it is specified on the command line. See the amanda(8) man page for more details about Amanda. AUTHOR
