Maybe you were asking about this?
A Backup (Ntbackup.exe) option to use when boot and system files become corrupt, preventing your system from starting in normal or safe modes, or using Recovery Console. This option is more desirable than formatting disks and reinstalling Windows because ASR restores system settings and critical files on the system and boot partitions.
The user interface to ASR backup is the ASR wizard in Backup, which steps you through the process of creating an ASR backup set and an ASR floppy. Windows XP Professional Setup provides the user interface to ASR restore.
Because the ASR process formats disks, consider this a last resort when using Last Known Good Configuration, Device Driver Roll Back, System Restore, or Recovery Console does not solve the problem. ASR is available in safe or normal mode.
Of course I tried starting this thing and telling it to create floppies, and it estimated about two days for the process to complete!
This utility can only use tape drives, floppies, Zip, or SuperDisk drives, not CD-R or CD-RW devices.
It DOES create a restore boot floppy as part of the process though.
