What is the difference between cpio and of ufsdump

www.unixbabuforum.inPlease clear the following doubt 

What is the difference between cpio and of ufsdump in Solaris


www.unixbabuforum.inIn single word I can tell you what is the difference between CPIO and 
ufsdump, 

CPIO is the file Backup... 
UFSDUMP is the Filesystem Backup... 


1.CPIO: 

-->This command is used to take the backup files from one place to 
another... 

-->It has a filter program by talking the i/p information from standard i/p 
and delivering the o/p to the standard o/p file... 

-->you can manipulate i/p and o/p using redirection symbols and pipelines... 

-->using CPIO we can backup individual files... 

-->The backup made by CPIO occupies less space than those created with 
tar... 

-->CPIO can span on multiple tspes,but "tar" doesn't... 

-->In CPIO,No absolute backup Only relative backup... 


THIS IS ALL ABOUT CPIO .... 

NOW, 

2.UFSDUMP:- 

--->ufsdump is for filesystem backup. 

-->Whenever we are having the backup with ufsdump every time it records 
ufsdup files and update to the /etc/dumpdates,which contains 3 fields 
1.filesystem 2. backuplevel 3.date and time
