UNIX for Dummies Questions & Answers

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

If you search this site for hp-ux backup you will find many discussions on backup for hp. Your using tar or cpio is probably not the best choice (for the reasons you state) so the other posts on the site should help...

The thread that RTM provided is a useful link to look at.

In brief, proceeding on the assumption you do not have any specific third party backup software, I would recommend using a fbackup in conjunction with a graphfile. This will allow you two split the backup between two tapes.

Create two files that contain the following:

File one:

i /
i /stand
i /tmp
e /var
e /volA
e /volB
e /usr

File two:
i /var
i /volA
i /volB
i /usr


If you have other filesystems that you have not mentioned place the appropriate letter before them in these grapfiles - i = include in the backup, e = exclude in the backup.

Now specify these graphfiles in the fbackup command:

fbackup -f [tape_device] -g /path/to/graphfile

Execute this command twice - once for each graphfile.
