In Windows server 2003, the word is Automated System Recovery.
If the server ever fails you simply restart with the Windows Server 2003 CD-ROM and selct the option to perform an Automated System Recovery.
The process uses the list of files on the ASR disk to restore standard drivers and files from the original Windows Server 2003 CD-ROM, and will restore remaining files from the ASR backup set?
To create ASR set, open the Backup Utility from the Accessories program group, or by clicking Start, then Run, and typing Ntbackup.exe. Click Advanced Mode. Then, from the Backup Utility’s Welcome tab, or tools menu, select ASR wizard. Follow the instructions of the ASR Preparation Wizard. You need a 1.44 MB floppy disk to create ASR floppy.
You can try a USB Bootable floppy...but there is the possibility it will not work.
