They are
designed
to
operate
through
the
CP/M
or
MP/M
operating
system.
(CP/M 2.2
or
greater is required.) The programs operate
directly
through
the CP/M
operating
system and are
completely
independent
of
the
size,
capacity
,
density
,
or
other
aspects
of
a
particular
disk
system.
Additionally,
all
interaction
with
the user is via CP/M's
console
drivers,
making
these
programs
completely
hardware-independent.
This
document
describes
how
to
use MUFBAR, version 2.0
or
greater. Version
2.0 is
completely
incompatible
with
earlier
versions.
If
you have created a
backup
file using
earlier
versions, you
must
use the old RESTORE
program. MUFREST
will
not
restore it.
The
discussion
assumes
that
the reader has a
minimal
working
knowledge
of
CP/M and
its
file structure.
2.0 BACKUP
This
system
will
make
backup
copies
of
one
type
of
file
at a time. The
file
or
group
of
files
that
you
want
to
back
up is
called
the
SOURCE FILE(S). The
files
which
will
receive the pieces
of
backed-up
file
are called DESTINATION FILES.
You
will
be
asked
for
a SPECIFICATION FOR SOURCE FILES. A
specification
may
designate
a
maximum
of
255
source
files.
Specifications
can be am-
biguous
or
unambiguous
CP/M
file
specifications.
Your CP/M
manual
has
details
on CP/M file-naming conventions.
Basically
, file names can have one
to
eight
alphanumeric
characters
and can be
followed
by a period
(.)
and a
file
type
of
one
to
three
characters
.
Wildcard
specifiers
, * and ?, may be used
to
specify
a
group
of
similar
files.
Names
of
files
need
to
be preceded by the LETTER OF THE DRIVE
which
con-
tains
the
files. If the drive
specification
is
omitted,
the
letter
of
the
current
drive
is used.
IMPORTANT NOTE: The drive
specification
of
all DESTINATION
files
must
refer
to
a
different
drive than the SOURCE
specification.
If you
do
specify
the
same
drive
for
source and
destination
drives, you
will
receive an error message.
WARNING: THE CURRENT DEFAULT DRIVE SHOULD NOT BE THE FLEXIBLE
DISK DRIVE.
For example,
if
A:
is the hard
disk
and
B:
is the
flexible
disk
,
then
the
CP/M
prompt
should
be A>,
not
B>.
