Peripheral Sharer

5.2.2 U

NATTENDED BACKUPS FROM

SEVERAL

PC

S

Most tape-backup drives support a
macro function that you can use to
perform regular unattended
backups. SMART allows you to
conveniently run a backup macro
from several PCs.  For example you
could use the following command to
run the “DAILY” macro at the end of
each day. If another PC is currently
using the tape drive, SMART will
wait until the drive is free and then
perform the automatic backup.

SMART   DAILY   LPT2

5.2.3 S

CHEDULED BACKUPS

Most good tape-backup drives
support a scheduled macro function
that you can use to perform regular
scheduled unattended backups.
Change the scheduled macro name
to the SMART command line. For
example, if the scheduled macro
name is WEEKLY then substitute
SMART  WEEKLY  LPT1.

If you do not have enough

memory to do this, create a batch
file as described in 

Section 6.1

and

change the macro name to the
batch-file name.

5.3 Sharing a Printer and a Tape-

Backup Drive

If your tape-backup drive has a feed-
through parallel port, then you can
use the Peripheral Sharer to share a
printer and a tape backup
automatically. Typically, the printer
would be shared during normal
office hours and the tape backup
would perform unattended backups
during the night. To share devices in
this way, connect the output from
the Peripheral Sharer to the tape-
backup unit and then connect the
printer to the feed-through port on
the back of the tape drive.

5.4 Sharing a Parallel-Port CD-ROM

Drive

5.4.1 I

NSTALLING

CD-ROM D

RIVERS

The Peripheral Sharer will support
sharing of certain CD-ROM drives.
The following instructions explain the
principles behind sharing CD-ROM
drives using the Micro Solutions
BackPack drive as an example. The
exact installation details will vary
between CD-ROM devices, but a
similar installation process may 
be used.

To install a shared CD-ROM, you

will need to be able to edit a DOS
batch file and have a basic under-
standing of the AUTOEXEC.BAT 
and CONFIG.SYS files. Please refer 
to your DOS manual if you require
further details.
