Thanks Perderabo,

To make things a bit more clear,
I use:

<pre>

mt -f /dev/rmt/0cn rewind // no rewind, so I have everything in the same dat tape

ufsdump 0uf /dev/rmt/0cn /dev/dsk/c0t0d0s0 //mounted on /
ufsdump 0uf /dev/rmt/0cn /dev/dsk/c0t0d0s3 //mounted on /var

ufsdump 0uf /dev/rmt/0cn /dev/dsk/c0t0d0s4 //mounted on /home

ufsdump 0uf /dev/rmt/0cn /dev/dsk/c0t0d0s5 //mounted on /u01
ufsdump 0uf /dev/rmt/0cn /dev/dsk/c0t1d0s0 //mounted on /u02
ufsdump 0uf /dev/rmt/0cn /dev/dsk/c0t1d0s1 //mounted on /u03

ufsdump 0uf /dev/rmt/0cn /dev/dsk/c0t1d0s3 //mounted on /u04
</pre>

So the above commands back up the root filesystem. When it finishes, the tape is left positioned after the root backup.

How do I backup the rest (inside files). I mean when for instance I backup /var/ does this mean that I back up everything inside the /var directory including all the sub-directories?

So I have several backups on the same tape. When I put the tape on and do a ufsrestore, you see only the first backup.(I suppose I have to rewind the tape before the restore , correct?

"Want to see the second backup? Do:
<pre>
mt -f /dev/rmt/0cn fsf 1
</pre>
first. This will skip the first backup and leave you positioned at the second."
what happens when I do a ufsrestore -i
Am I able to choose ??

Thank you for your help

device_maps

device_maps(4)							   File Formats 						    device_maps(4)

NAME

       device_maps - device_maps file

SYNOPSIS

       /etc/security/device_maps

DESCRIPTION

       The  device_maps file contains access control information about each physical device. Each device is represented by a one line entry of the
       form:

       device-name : device-type : device-list :

       where

       device-name	       This is an arbitrary ASCII string naming the physical device. This field contains no embedded white space  or  non-
			       printable characters.

       device-type	       This is an arbitrary ASCII string naming the generic device type. This field identifies and groups together devices
			       of like type. This field contains no embedded white space or non-printable characters.

       device-list	       This is a list of the device special files associated with the physical device. This field  contains  valid  device
			       special file path names separated by white space.

       The device_maps file is an ASCII file that resides in the /etc/security directory.

       Lines in device_maps can end with a `' to continue an entry on the next line.

       Comments may also be included. A `#' makes a comment of all further text until the next NEWLINE not immediately preceded by a `'.

       Leading and trailing blanks are allowed in any of the fields.

       The device_maps file must be created by the system administrator before device allocation is enabled.

       This file is owned by root, with a group of sys, and a mode of 0644.

EXAMPLES
