VECTOR 4 USER'S
MANUAL
DISKETTES
From
time
to
time,
you may
encounter
an individual diskette which
may
not
work.
Some
computer users have occasionally found a batch of
diskettes
with
the
wrong number
of
sector
holes, with two diskettes mounted
in
one jacket,
or with other manufacturing defects. If a
diskette
does
not
work, and work
reliably, replace
it
immediately.
If
you
have
any
very
old
records
or
tapes,
you know
that
any electronic
recording
medium
will gradually deteriorate with time. But where an old
tape
or
album will begin
to
hiss and crackle
after
a few years, an
old
diskette will
begin producing errors.
You
can avoid
this,
not
to
mention
the
subsequent
problems,
by
making backup copies from time
to
time. Both program diskettes
and
data
base diskettes should be backed
up
on
a regular schedule.
Backup
The
best
defense
against
loss of diskette-based
data
is
to
maintain a backup
diskette for each diskette you use. Some
users
keep
a copy
of
valuable
or
confidential
data
in
a
safe,
or in some other secure place where
it
will be
difficult
to
change
the
data
or
destroy
the
diskette.
It
is
a good
idea
to
place
the
extra
key
that
came with your Vector 4 in the same location.
Make
a backup copy regularly, whenever you have more
information
than
you
can
afford
to
lose.
In
addition,
a
transaction
journal,
a
printed
copy of
entries made each day into
the
system, is an excellent idea
to
build
into
your
procedures
as
a
"last
resort"
backup.
With
the transaction journal, you will
always have a record of what went on during a
given
day,
so
that
you
can
rebuild the day's work with a
minimum
of
effort
should you accidentally lose a
diskette.
As
you gain experience, you will probably find
the
backup system and
schedule
that
best suits your business.

To The Backup Diskette
To record information onto a diskette, use
any
of these programs:
DISKCOPY
STORE
PIP
Use DISKCOPY and STORE for the entire contents of a disk
(DISKCOPY
for
floppy
to
floppy,
STORE
for hard
to
floppy). Use PIP
for
individual
files,
files
with
similar
names
or
extensions
(allowing you
to
use ambiguous file
names as described in the
INTRODUCTION
TO
VECTOR
4 CP/M),
or
files
to
be copied from one user
area
on a disk
to
another.
