Discussion
With MS-DOS, Microsoft provides MSBACKUP for MS-DOS as well as for
Windows. You
determine if one or the other (or both) will be available by the choices
you
make during MS-DOS Setup. The discussion below relates only to backup
for
MS-DOS.
NOTE:
You can only run MSBACKUP from a hard disk, not a floppy disk.
MSBACKUP allows you to back up all files on a disk or only files that
have
changed since your last backup. You can also schedule backups to be
performed
automatically on a regular basis.
When MSBACKUP is used to back up your files, a backup catalog is
created. This
catalog contains information such as backed-up disk`s directory
structure, the
names, sizes, and attributes of the directories and files that were
selected,
the total number of files, backup date, etc.). If you want to restore
one or
more files, you can do so easily by loading the backup catalog and
selecting the
files to be restored from the backup set.
Setup_file specifies the setup file that is to be used to define the
files to be
backed up as well as the type of backup you want MSBACKUP to perform.
The setup
file is created when you save program settings and make file selections.
You
must give setup files the SET extension. If a setup file is not
specified,
MSBACKUP will use the DEFAULT.SET file.
Options
/BW - Starts MSBACKUP using a black-and-white color scheme.
/LCD - Starts MSBACKUP using a video mode compatible with laptop
computers.
/MDA - Starts MSBACKUP using a monochrome display adapter.
