Backing Up Your Data

This section deals with protecting the information in the
DigiGate-700™ for Windows
database.
Having a competent backup procedure can prevent many hours of frustration and down time at
your location.
In the computer world there is a saying: “There are two kinds of users, those that have experienced
a major system crash (data loss), and those that are going to!” Anyone that has experienced the
loss of their data is now well aware of the value of proper backup procedures and of following
them closely.
The
DigiGate-700™ for Windows®
program uses the ZIP format as the means to protect your
data. This maintains consistency with most existing backup systems and provides for data
compression choice, multiple disk backups, and selection of many different data storage devices
like tape drives or Zip drives. Microsoft has changed it backup system in recent versions making it
difficult to maintain consistent backup procedures. The backup feature in the software was added
to provide a consistent process for archiving data and program setups.
The following will provide some basic information on the Digitech backup utility. Any other
backup device’s software may be used in place of or in addition to the DigiGate method provided
in this section.
Introduction
A back up strategy is a plan for the regular backup of data, usually at several different levels, and
for a period of time sufficient to minimize the effect of any loss.
There are times when data corruption can remain unnoticed for a period of time. When this
happens you can make corrupted backups that may be used at a later date to restore data that has
been lost. To prevent this type of occurrence, backup strategies are planned in a tiered structure.
This allows the restoration of data on several different levels, depending on how long it took to
become aware of the corruption.
The simplest strategy is to do a full backup of your system at regular intervals (daily, weekly, etc.)
and to save them for as long as you think it is necessary.
The most complex is a system of master backups done on a monthly basis with sub masters done
weekly and an incremental or differential done on a daily basis using different media for each day
until two cycles of the master backup have been completed.
Since the amount of data in the
DigiGate-700™ for Windows®
system is not that large, the
simple strategy is sufficient and provides the best protection.
We suggest a daily backup on a floppy, keeping at least 3 weeks data before reusing the disk. You
may also keep a monthly master of the data for several months to insure against a total loss.
If you do a regular Full System backup on tape or some other media, use the following pages to
add the DigiGate data files to your data set.
BETTER SAFE THAN SORRY!!
