MS Backup (DOS) password recovery

July 1, 2018 at 06:56:55
Specs: MS DOS
I have some information trapped into MS Backup (DOS) file because I do not remember the password that I set when I created those backup files at 1996. So I need to reset the password protection.

Any Ideas?

Hi Campo,
I would try creating another backup using a new password.
Then search the new backup file for the location of that new password.

If lucky and you find it, try looking in the same location of the old backup file.

Good Luck - Keep us posted.

Hey Mike, thx for posting!

The original files are lost; I just have those MS Backup files. I cannot create another backup from the original files. Did you mean to create a different backup from different files, and mix this new backup file with the old ones?

Hi Campo,

just try backing up a few NEW files into a NEW Backup File.

Then see if you can locate whatever password you used in the NEW Backup File.
DEBUG might help.

Maybe you will get lucky.

Good Luck - Keep us posted.

Hi Mike!

I do not know use Debug... I thought that I had to edit the MSbackup file with the MS-DOS text editor "edit" he he he.

Let me figure out how to work with debug command

Hi Campo, that Editor is good.
.
Somewhere in that file is the password you used.
It could be at the start (more likely) or the end.
Try the 'Editor 'Search' Facility.

You may be lucky and be able to find it, if it has not been converted in order to hide..

If you are lucky, once you know where it is situated you should be able to find same on your OLD backup file.

Good Luck - Keep us posted.

Thanks Mike. I am trying just right now. I will post again with my results.

I am sorry because I did not understand at the first time.

It is my first time doing this class of things, I am enjoying it.

Thanks again.
