.ma and .mb are version 2 extensions for Mathematica files. As far as I 
remember, the .mb file was a graphic file. With version three, all 
notebooks are self contained in a .nb extension file.

If you are using a version 2.x and do not wish to upgrade to version 3,
you  have to keep your .ma and .mb files together. In no case these can
be  considered as backup files. Even with version three, you have to
make these  backups by yourself (save as:  myFile_old), or have an
automatic backup  system (on a daily base for instance).

Hope this helps,

I have a question: Does Mathematica produce backups of its files ? If
you save your file you always have one file with the suffix MA, and
another (older) one with the suffix .MB . But if Mathematica halts for
whatever reason and you try to reload the .MB file it doesn't work. So
- for what reasons do those .MB files exist, and how can I get
Mathematica to produce backups ?

Thanks in advance,
