 Hi,
 As per 'vinum' in the handbook, we cannot do the mirroing for System files. 
 we can do only to Data partition. Other wise we have to do the RAID-5. Any 
 other way we can implement mirroing.

If I understand what you are saying - this is not true.  You can
do mirroring on the systemn slices too.

Please post to the list too and not just me.   Other people know much more
about this than do I.

 HI,
 We having free BSD 4.8 Server  for backup, we are copying and write all in 
 CDs.
  
 Is there is any provision for 
 
 a)implementing disk mirroring in Free BSD server (for both System  
 Datafiles) 

Yes.  Look up 'vinum' in the handbook.

 b)Is it possible to make any backup NIS server, which will backup the 
 data  will come up when Primary server goes down.

I think it is a bit more complicated than you state it.  Better let
someone else answer that.

 
 Can you please revert with details.

?? Do you mean 'reply' with details?

 Thanking you
 Rathan

This has already been answered.  vinum, ccd.

b) Is it possible to make any backup NIS server, which will backup the data 
 will come up when Primary server goes down.
Yes, it's possible to promote a backup NIS server to be the master if the master 
NIS server goes down.  Normally, that level of failover doesn't need to happen: 
if you have a problem and the master goes down, the clone server stays up 
read-only while you fix the master.  You'd promote the backup/clone NIS server 
only if you couldn't fix or restore the master...
