Backup NTFS

NTFSD
1

Hi Guys,

I am a CS student and wants to write a simple backup utility for NTFS. The
question I have is it possible to boot the system in DOS and mount the
NTFS and start the backup. In a way quite someting like NTFSDOS
Professional
(http://www.sysinternals.com/ntw2k/freeware/ntfsdospro.shtml).

Could anyone help me to understand how to go about doing this?

Thanks in advance.

Raman

There is a special console only boot option for Windows - is that what
you are looking for? If you want to really boot DOS, then what about
using NTFSDOS?

Hello,

you do not need booting to DOS, I suggest that you looked at the
snapshot IOCTLs supported by NTFS. You can backup NTFS w/o rebooting.

BTW, we’ve developed an utility that allows backing-up both FAT/NTFS w/o
rebooting:

The only way to you access NTFS from DOS is to use NTFSDos or smth like
this.
But in fact you can backup entirely partition (raw backup), or thy to use
Linux-NTFS sources.

Well, I think I should had made it clear earlier. I am in the process of conceptulizing a project for my Course requirmnt (4 months). So, lot of things not still clear to me, probably that’s the reason for the confusion.
Let me try to expalain myself again.
I want to backup NTFS (only) file system and don’t want (or let’s say - The system is not bootable now) to use Windows itself. I sould correct myslef here its NOT BACKUP - It should be recovery. So, in a way its quite similat to NTFSDOS, but I want to programm it myself. What I could understand is, I can boot the system in DOS and use Network redirector to acess NTFS - Any code sample or reference will be very helpful to me.
Now, if this is clear, then what I am asking is, can some one give me some details, so that I can research and workout the details.
Thanks again for taking time in responding.

Linux NTFS source is a good reference.

Yes. Also, you probably don’t need to write DOS redirector, it is
complicated and mostly undocumented work. NTFSDOS is implemented this way
because it wants to create drives accesible by other apps. If you need only
utility, you can simply read sectors and interpret NTFS data. It is hard
enough; redirector would only double your problems.
