ASS=
tells TRSDOS-II not to prompt you
if
the specified
drive contains data.
ASS
is
optional; if
ABS
is
omitted,
TRSDOS-II will prompt before overwriting any data that
already exists
on
the floppy disk.
This utility allows
you
to
make a "mirror image" of a TRSDOS-II
floppy diskette onto another floppy diskette. Diskettes do not need
to be formatted before BACKUP. BACKUP automatically formats
during the
track~by-track
dupl'lcation.
Note: BACKUP
is
used for floppy-to-floppy duplication only,
If
you
want floppy-to-hard, use FCOPY, SAVE/RESTORE,
or
COPY
The TRSDOS-II BACKUP utility
IS
much faster than the TRSDOS
BACKUP because it makes a "mirror image"
on
a track-by-track
basis instead of file-by-file.
Single-drive BACKUPs are not allowed with the TRSDOS-II
BACKUP command.
TRSDOS-II BACKUP will not allow the following TRSDOS options
• wildcarding
• prompting before each file
• NOAUTO
•
SYS

Making SAVE/RESTORE Compressed Copies
This section
is
an
introduction to the TRSDOS-II
SAVE
and
RESTORE utilities.
The
SAVE
utility stores files
in
a special, compact form
on
floppy
diskettes, Because of
the
special format, files occupy less space
than they normally would
on
floppy diskettes,
TRSDOS-IJ
cannot
directly read files stored
in
this format.
The
RESTORE
utility returns saved information to a disk formatted
under
TRSDOS~II.
It
is
the only way
to
retrieve the information
stored by
SAVE.
SAVE
is
a good way
to
make archive copies of hard disk files.
To
dedde
hoW
often to make save cop'les of your hard disk files, think
how much time, effort, and money could be lost
if
your hard disk
files suddenly were destroyed.
We
suggest hard disk users keep •
two major sets of archive files:
