Todays standalone PCs come with very large hard disk drives, 4GB,
6GB, 8 GB and more of internal storage. And yet users who dont have
the administrative security of a network backup protocol dont
adequately consider how they will back up all that data to protect their
companys most cherished asset information. Small businesses are
the most consistent risk takers here, as if they didnt have to worry
about losing customer files, receivables records, product cost
statistics, strategic planning models, Bill of Materials details, etc.
There are two parts to effective backup practice:
1. The first is having a sound company policy that states clearly
that critical data will be backed up daily. Use several generations of
backup for added protection from faulty tapes and accidentally backing
up corrupted files. The practice we follow in our office uses 6 tapes
and looks like this:
- Beginning of week 1: complete backup all hard drives containing
programs or data onto Tape 1.
- Each day in the following week: backup all files modified since the
weekend onto Tape 2.
- Beginning of week 2: complete backup all hard drives containing
programs or data onto Tape 3.
- Each day in the following week: backup all files modified since the
weekend onto Tape 4.
- Beginning of week 3: complete backup all hard drives containing
programs or data onto Tape 5.
- Each day in the following week: backup all files modified since the
weekend onto Tape 6.
- Beginning of week 4: Begin the cycle again, starting with Tape 1. And
so on, and so on.
2. The second part is being able to back up your data automatically,
without an operator in attendance. That means backup that turns on,
backs up, and turns off without your intervention. And without your
having to remember, and take the time to do it, and lose the use of the
systems full capability while the process is taking place. Unattended
backup means backup that usually takes place during the night, when the
business is closed. Unattended backup means backup that does not require
a second tape to complete. And that, my friends, means buying a PC with
a tape backup capacity that is equal to your usable hard disk drive
capacity.
How large is that, exactly? Seagate Technology makes an internal tape
drive that will hold 4GB of data (8GB compressed), priced at $330 to
$390 according to PC Magazine (Seagate TapeStor Travan 8GB). The
drawback is speed, and a full 8GB of data might take all night to back
up and then some. A higher speed and higher cost option is a
removable hard drive. While they dont compress data, the best of
these devices move as fast as internal hard drives and hold up to 5GB of
data as of this writing. The cost of one such unit (Summatec MobileDrive)
was $120 plus $560 for a 5GB cartridge.
Make your data backup automatic, not occasional, with smart use of
hardware and unattended backup options. That way the next system crash
horror story making the rounds wont be yours.
