Hard Drive Backup

**manipura** · 07-31-2004

Hi everyone,

I would like to make a complete backup of my hard drive with red hat 9 on it. Its running a server that I cannot lose. I want to make a complete duplicate of this hard drive, so if the one fails, I can just pop in the other and have it up and running ASAP.

Anyone know how I can do this?

Code:

dd if='/dev/hda' of='/dev/hdb'

IIRC

Thank you! very much! I've been looking for software or ways of doing this for weeks! Can't believe it was that simple!

So I tried it on one machine.
Put in Hard Drive As Slave
Boot Computer
#dd if='/dev/hda of='/dev/hdb'

1234567 in
1234567 out

It almost worked fine, I swaped the drives and put in the one I copied it to.
For the exception of the error when I logged in (i had it writen down
somewhere but can't find the actual error. )

Then I put the same drive in another computer and followed the exact
same steps to copy its master drive, swaped the drives, and it had lots or
crazy file system errors. Would that be because I already have a linux OS
on the drive? Do I have to format it or something?
