First : i'd like to thank every one for his care
second : forgive my language
i will list you all details to help me if you can as i hope :
as i told before that in my company i was responsible for installing NMS ( Network Management Station ) called Naviscore which needed to configure, monitor, and control a Lucent switch network so to build such station you need the following Software:

Solaris 2.6 and Common Desktop Environment
Sybase 11.9.2 SQL Server
Open Client 11.1.1
HP OpenView 5.01
NavisCore 05

as you see that the system is too large and it takes too time to work . there is no problems till now but the problem located in what we built in such system simply we have 50 lucent device managed ,configured every thing you can imagine will be controlled via our Server also you can note from Software required >> sybase which mean that there exist huge data will be stored . simply all what others built through more than 8 years .

so there is a spare Machine which i use in my work and built a demo version of our work then backed up the full system ( with the same way the current server work ) and i'm trying to Restore it .
so we can rescue our current system easily and in fast way as possible we can .

i already tried the Restore command which is " ufsrestore xvf /dev/rmt/0n /opt " but i faced more errors as i don't know what he asked me for as example of errors messages :
read error while skipping over inode4 unless you know which volume your file are on you should start with the last volume and network to wards the first}.

If i but any number and press yes this last error is appear but if i press no and rewrites this command again this error is appear {media read error: I/O error}.

Thanks again waiting your replay

If I understand properly, you want to clone an existing server to another one.
Is that spare machine the very same model as the first one ?

let me clear things more i have already server running with the above mentioned SW . i backed up the system using ufsdump then i need to restore it using ufsrestore :
1- if it success and all system recovered again with all things as i hope it will be a great thing for me .
2- if it fails as not expected i need to know how to clone the server on external media then recover the system in case any disaster occur

As already stated, you backup is dubious. There is a risk for you to break your production platform by performing a restore from that media.
2- if it fails as not expected i need to know how to clone the server on external media then recover the system in case any disaster occur
Then it would help if you answer my second question.

Basha, here is an example of the process of doing a ufsdump/ufsrestore -

Making the backup...

    * Find a tape and load it into your tape device. The tape device in 
this exmaple is /dev/rmt/0
    * You may want to bring the system down to single user to make the 
system as quiet as possible.
    * Keep a record of how the partitions are set up by going into format 
and copying the table to a flat file or printing it out. Just put it 
somewhere that you can have access to it in the event that the disk's 
partitions are totally lost. Below is an example of what you want to 
record. To get to this information just su to root, type format, then pick 
the disk you're backup up, then type in partition, then print.

    * For even more record keeping grab the /etc/vfstab file and do a df -k 
to confirm what slices are being used for what. Either print this or keep it
 in a file somewhere accessible for when the server in question is not 

          o Backup each of your separate file systems. In this case we have
 /var, /usr, /opt and /. Remember or write down the order in which you do 
each backup.
          o ufsdump 0uf /dev/rmt/0n /
          o ufsdump 0uf /dev/rmt/0n /var
          o ufsdump 0uf /dev/rmt/0n /opt
          o ufsdump 0uf /dev/rmt/0 /usr
          o That is the extent of ufsdump. After this you will have a good 
backup, so keep that tape handy.

      To do the restore ...
          o Get the server in question to the OK prompt
          o boot cdrom -sw ( s means single user, w means no windows )
          o format ... to see if partition table is the same as it used to be. 
If not, re-partition.
          o Time to build a new file system on each of the partitions that need it.
          o newfs /dev/rdsk/c0t0d0s0
          o newfs /dev/rdsk/c0t0d0s3
          o newfs /dev/rdsk/c0t0d0s4
          o newfs /dev/rdsk/c0t0d0s5
          o Do a files check on each of the new file systems.
          o fsck /dev/dsk/c0t0d0s0
          o fsck /dev/dsk/c0t0d0s3
          o fsck /dev/dsk/c0t0d0s4
          o fsck /dev/dsk/c0t0d0s5
          o Do the actual restore, restoring one file system at a time. Make 
sure you remember which backup is for which partition. For instance, if 
the first file system you backed up was / , then remember to restore the 
first backup to the appropriate slice. See below.
          o mount /dev/dsk/c0t0d0s0 /a
          o cd /a
          o ufsrestore rfsvy /dev/rmt/0 1
          o cd /
          o umount /a
          o mount /dev/dsk/c0t0d0s3 /a
          o cd /a
          o ufsrestore rfsvy /dev/rmt/0 2
          o cd /
          o umount /a
          o mount /dev/dsk/c0t0d0s4 /a
          o cd /a
          o ufsrestore rfsvy /dev/rmt/0 3
          o cd /
          o umount /a
          o mount /dev/dsk/c0t0d0s5 /a
          o cd /a
          o ufsrestore rfsvy /dev/rmt/0 4
          o cd /
          o umount /a
          o Install the boot block.
          o cd /usr/platform/sun4u/lib/fs/ufs
          o installboot ./bootblk /dev/rdsk/c0t0d0s0
          o The restore is now finished. If this is a test to restore a server 
that is still working, you would need to change the IP of this 'test' server 
or disconnect the network cable.  Reboot the server and it should come

Basha - that basic ufsdump/ufsrestore doesn't give you everything you may need for building out a naviscore server. Those are a very picky system to build out normally (requirement of Solaris 2.6, specific patches, Sybase, HP-OV (and it's patches)).

If you are doing mirroring with Disksuite (recommended), then you could drop side of a mirror and run your ufsdumps from it. This would give you a clean dump versus running it against a live system.

Also, I don't think you specified if you are looking at rebuilding the database server or the client(front-end) (I'm assuming you have separate servers for this) or both. As far as insuring you can recover a DB server, you should be dumping the database at the least, every hour.
