Partition image on the fly



  Hi! 


  It is possible to make partition image on the fly? With the system (*Linux 
server) running? 

  I think in the aproach: At midnigth (less system use), the script remounts 
partition readonly by some minutes while put the output of 'dd if=/dev/...' 
to a file in another HD on the same machine. Some word? Some trouble in do 
so? 

 * The server is running several services like internet, mail, web, jabber, 
mysql. I want to make a diary backup of it. Hardware resources are not 
problem, I can use another machine, or DVD writer or another HD or the three 
options together. 


  If it is not possible, what do you think about mount the system from 
another system in the LAN via NFS, and use simple 'cp -R /mnt/nfs-server/ 
/backup/'? Obviously excluding dirs like /proc, /mnt, etc. 



  PS: I already search google, tldp, etc and didnt find nothing with this 
specifity level. 



  Thank you 
  Tom
