Installation
Installation is straightforward. Simply insert the disk containing
FLEXIBAK Plus into a drive, then select the current drive by typing
"A:" or "B:", as appropriate, and press <ENTER>. Now, type "INSTALL",
press <ENTER> and follow the instructions.
You are asked to specify a source drive and destination directory,
which default to "A" and "C:\FLEXPLUS", respectively. INSTALL will
then unpack the FLEXIBAK Plus files into the directory you specified.
To run the program, change to that directory, and type, "FLEXPLUS".
Setting The Alarm
FLEXIBAK Plus has an alarm feature that warns you if you haven't taken
a backup recently. To enable this, you must place the following lines
in your AUTOEXEC.BAT file (generally found in the Root directory of
your hard disk) in an appropriate place. (If you are unsure about the
function of the AUTOEXEC.BAT file or how to alter it, please consult
your MS-DOS reference manual).
x:
CD \FLEXPLUS
FLEXPLUS /A=y
C:
Where "x" is the hard disk drive where you installed FLEXIBAK Plus --
if other than drive C -- and "y" is the number of days after which you
want the alarm to sound. Many users set "y" to "7" for a weekly
backup; others do it more frequently -- even once each day. Only you
can determine how often to backup programs and data in your
circumstances, based upon how much work you can afford to lose when
the inevitable happens someday and files become lost or damaged.
After you have done this, every time you boot your computer FLEXIBAK
Plus will determine if the time since the last backup is longer ago
than the specified threshold - "y" in the above example. If so, an
alarm will sound to remind you to take a backup.
Command Line Parameters
If you are running on a machine with a particularly low amount of free
memory or a particularly high number of files, you may have trouble
getting started with FLEXIBAK Plus, as it will abort with an exception
message saying that it has run out of memory, file space or directory
space.
If this occurs, override the initial memory allocation settings of
FLEXIBAK Plus with command line options. (These can later be set
permanently with the General Setup option of the Setup menu.) To
override the number of default number of files (4000), use the "/F"
command line option. To override the default number of directories
(300), use the "/D" command line option. For example, if you have a
particularly large hard disk, you might use a command like this:
FLEXPLUS /F=5000 /D=500
This example tells FLEXIBAK Plus to allocate space for 5000 files and
500 directories. If you are short of memory (FLEXIBAK Plus requires
about 520K FREE memory in order to run with its default setting of
4000 files), you should try reducing the number of files by using a
command such as:
FLEXPLUS /F=2000
Make sure that the number of files you specify is at least 100 greater
than the number of files on your drive C, and FLEXIBAK Plus should run
correctly.
There is one more command line parameter -- "/N". If you use this
parameter the FIRST time that FLEXIBAK Plus is run, drive C will not
automatically be used as the logged-in drive. Use this parameter if
you have too many files on drive C for FLEXIBAK Plus to handle as one
backup drive or you only want to backup selected directories or files.
