Preparing for NT Server disaster recovery
The following steps must be taken before a disaster occurs to
set aside the information and resources needed to recover a failed NT server.
- Know the OS level of each server, including service paks and hotfixes.
- Using REGEDT32, save the HKEY_LOCAL_MACHINE\SYSTEM\DISK key
to another disk or floppy. This needs to be done only after a partition,
drive letter, volume, or stripe set has been changed or added.
- Using REGEDT32, save the HKEY_LOCAL_SYSTEM key (even though
it will also be on the recovery disk created by RDISK).
- Run RDISK/S to update all of the system registry keys in %systemroot%\repair.
Then run RDISK to make backup disks.
- Back up the MBR using the 'diskprobe' utility (from the WinNT
resource kit). Do this whenever a volume is formatted, NT is installed,
or a volume changes from FAT to NTFS.
- Make a bootable floppy, as follows:
- use format A: to create the floppy
- put the 'disksave' utility (from the WinNT resource kit) on
the floppy. This can be used to fix the MBR on the HD.
- copy the following files to the floppy:
- BOOTSECT.DOS (if you need to dual boot)
- NTBOOTDD.SYS (if scsi(), not multi(), syntax is to be used in BOOT.INI)
- If the machine is RISC, also:
- create an \OS\WINNT40 dir on the floppy
- put the following files in that directory:
- Since RISC boots from NVRAM, define an NVRAM selection that points
to an NT startup floppy.
