off topic / image or mirror drive software needed

["Bilo Selhi" <citadel@xxxxxxxxxxxx>]

list,
i need a pointer on the following matter.

i need to be able to make a back up or image or 
mirror copy of 
my master drive, say once a week or a day...
in case of failure of the main drive or corrupt
operating system i want to be able to 
plug in the mirrored drive and boot to it in 
a matter of minutes.

so,  i got me a second drive and i the removable 
tray and all. 
but i lack good software to be able to do it.
i have dos based "drive copy" and "drive image"
but those don't work real well ( i get errors 
while copying drive, etc ) and i don't feel comfortable 
using it.

the question is:
- is there a reliable way to back up or mirror or 
image your hard drive onto another hard drive 
so that in case of sudden failure for whatever 
reason i can just plug in the back up drive, boot 
up to it and i am ready to go in under say 
10 minutes...
needs to be ***reliable, fast and simple to use
and win2000 compatible or dos...?
- is there software that does that reliably and 
specifically designed to do that on win or dos 
operating system?

i want to be able to make the exact copy of 
the master partition which contain the operating 
system every day or at least every week
reliably?

maybe drive duplication software or something like that?

so far i have found novabackup and xactcopy but 
was wondering if there is anything else out there that 
will do it.

thanks.
bilo.
