Hi  ismahwati,

   You need to do the followings to perform a full backup for your system.

   1. su as root.

   2. Have a look at /etc/vfstab to see your systems' layout:

   The file should look like the followings:

  #-------------------------------------------------------------------------------
    #device         device          mount           FS      fsck    mount   mount
    #to mount       to fsck         point           type    pass    at boot options
    #
    #/dev/dsk/c1d0s2 /dev/rdsk/c1d0s2 /usr          ufs     1       yes     -
    fd      -       /dev/fd fd      -       no      -
    /proc   -       /proc   proc    -       no      -
    /dev/dsk/c0t0d0s3       -       -       swap    -       no      -
    /dev/dsk/c0t0d0s0       /dev/rdsk/c0t0d0s0      /       ufs     1       no      -
    /dev/dsk/c0t0d0s6       /dev/rdsk/c0t0d0s6      /usr    ufs     1       no      -
    /dev/dsk/c0t0d0s1       /dev/rdsk/c0t0d0s1      /var    ufs     1       no      -
    /dev/dsk/c0t0d0s7       /dev/rdsk/c0t0d0s7      /export ufs     2       yes     -
    swap    -       /tmp    tmpfs   -       yes     -

  #-------------------------------------------------------------------------------

   from the above table, you can see you have 4 file systems to be backup. (/, /usr/, /var and /export)

   3. type in the following comand to backup your system to the tape: (I assume that your tape device is /dev/rmt/0,
if not just replace it with the one you have)

    mt -f /dev/rmt/0 rewind

     $ for fs in / /usr /var /export ; do
     /usr/sbin/ufsdump 0cf /dev/rmt/0n $fs
     done


   This will do the job for you.

You don't have to shutdown the system before doing the full backup. But it is good to do the full backup while there are not many process running.

It is nice to run it in single user mode, but you can do your backup in multiuser mode.

Hi,

There is a script in my 'Scripts Repository' called backup_unix.sh

From my home page, click 'Scripts' on the left and then 'Scripts Repository'.  It is the first script.

Look at www.backup-central.com for a script called hostdump.sh. Also if you are involved in backups you should really get a copy of Unix Backup and Recovery from the O'Reilly stable - it covers everything you ever wanted to know on the subject!

Cheers - Gavin
