ERS NT, Emergency Recovery System

Features and Instructions:
--------------------------
ERS NT does two Windows main files backups and three
Registry, all Profiles NTuser.dat and boot files backups for Win NT (FAT/FAT32).
ErsNT needs few Win95 or Win98 MS-DOS files to be placed
in the ErsNT directory to backup and restore.

NOTE:
----
Please read the Backup and Restore section of the Help file about
backup and restore summary check list.

Windows main files Backups:
--------------------------
Windows main files backup are made from within the Windows environment
and get zipped in the ErsNT\Zipped folder.

Windows main files don't include the Registry files.
Click either Windows #1 or Windows #2 button to make the backup.
Depending on size and speed of computer, it will take about 3 to 12 minutes.
A restore batch files gets created and placed in the ErsNT directory,
Win1.bat for backup #1 and Win2.bat for backup #2.
Restore has to be done from the MS-DOS prompt.

Registry , all Profiles NTuser.dat and Boot files Backups:
---------------------------------------------------------
As most of you know that you can't copy the Registry files while in the
Windows NT environment, backup and restore has to be done from
the command prompt.

Open ErsNT.exe and click the Make Backup And Restore batch files
button, it will create 9 batch files:

3 Registry, all Profiles NTuser.dat and boot files backup batch files called:
Backsys1.bat
Backsys2.bat
Backsys3.bat
3 Registry, all Profiles NTuser.dat and boot files restore batch files called:
Restsys1.bat
Restsys2.bat
Restsys3.bat

Recreates Win1.bat and Win2.bat.

And lastly, it creates ErsNT.bat and Ers.bat, type Ersnt at the command prompt,
ErsNT.bat will popup and give you instructions on how to backup and restore.
Ers.bat and ErsNT.bat are the same.

Every time profiles are changed and you want to make a backup,
then a fresh set of Batch files has to be made before backing up.

Backup and Restore:
------------------
As explained earlier, Windows files backup are made from within the
Windows environment.

To restore the Windows backups or backup and restore the registry,
has to be done from the command prompt.
ERS NT needs the aid of some of Win95 or Win98 MS-DOS files:

Command.com
Attrib.exe
Choice.exe
Deltree.exe
Edit.com
Io.sys
Xcopy.exe
Xcopy32.exe
Xcopy32.mod(Win98 only)

All these files except Io.sys has to be copied to the ErsNT directory,
without these files ERS NT backup and restore can't be carried out.
Command.com and Io.sys has to be copied to the root directory C,
unless you already have these two files in the root directory C.

If doesn't already exist, add the following line to the bottom of the
Boot.ini found in the root directory C.
C:\ = "MS-DOS"
Boot.ini, is Hidden and Read only.
In the Windows Explorer, click View\Options and select "View all Files"
and click OK. Scroll down the root directory C to the Boot.ini, right click
it and select Properties, in Properties deselect Read Only and click OK.
Double click Boot.ini and select to open it with Notepad, scroll down
to the bottom of the page and Copy\Paste:
C:\ = "MS-DOS"
Save changes and set its Attributes back to Read Only.



Start computer, select MS-DOS from the NT boot menu,
if you don't have the Command.com and Io.sys in the root directory
then it will give you error message, unless you are booting from ErsNT
boot disk.

Once at the command prompt, type:
--------------------------
ERSNT
it will change directory to the ErsNT directory. if it didn't change directory
then change to the drive ErsNT installed in and type:
CD ERSNT

There, if the ERSNT instruction page didn't popup then type ERS.
It will give you instructions on how to backup and restore.
Type:
Backsys1, Backsys2 or Backsys3 to backup the Registry files.
Type
Restsys1, Restsys2 or Restsys3 to restore from desired Registry backup.
Type
Win1 or Win2 to restore from Windows #1 or #2 backups.

Please print this page and save it.
NOTE:
----
You may need to add the .bat extension to the backup and
restore commands.

NOTE:
----
Every time you open ErsNT.exe it recreate a fresh ErsNT.bat,
make a habit to open ErsNT.exe every time you make a new backup.

*****
NOTE:
*****
If ERS NT is installed in a non English WinNT and profile names
has extended non English characters ,  etc. then it will give error
in MS-DOS backing up and restoring profiles NTUser.dat, because
MS-DOS doesn't recognize extended non English characters.
Suggest to change profile names to names without the non
English characters.

ERS Boot Disk:
-------------
-- Before making the ERS bootdisk, be sure to click the 
   "Make Backup and Restore batch files" button.
-- In order for the ERS NT boot disk to work:
   1) DON'T use WinNT formatted floppy, use Win95/98 only to format

       the floppy.
   2) DON'T use third party formatting tools and formatting with
       MS-DOS will NOT work with Win95 or Win98 bootdisk files.

-- Copy the following files to the ErsNT directory first.
   Use only Win95/98 files.
   If using Win98 MS-DOS files then Xcopy32.mod would be needed.
   Command.com
   Attrib.exe
   Choice.exe
   Deltree.exe
   Edit.com
   IO.sys
   Xcopy.exe
   Xcopy32.exe
   Xcopy32.mod(Win98 only)


LEGEND:
------
Where C:\ is mentioned, its considering "C" is the boot drive,
Where Windows is mentioned, its considering WinNT is the Win NT

Windows Directory.
ERS NT runs in NEC computers that uses A as the boot drive
and would recognize the Windows directory no matter what name
it is called.
Also would recognize the StartMenu in any language.
Also recognize all Profiles.
Where Registry or critical is mentioned, it means the Registry files,
all Profiles NTuser.dat files and boot files.
