To the best of my knowledge, this problem is ONLY with MS-DOS v3.20.
There was an upgrade which fixed this (among other things), MS-DO 
v3.21. So, other than MS-DOS v3.20, all DOS versions use a "\" to
store the full filename when backing it up. I've seen a program on
some BBS which did nothing but read MS-DOS v3.20 backup files and
replaced a "\" with a "/". (Note that MS-DOS v3.20's RESTORE utility
did correctly read the files produced by the MS-DOS v3.20 BACKUP.)
