We all know how important it is to keep the computers in our lives backed
up. We also know that the open secret is that few really do this properly.
I hope that these backup methods and strategies will make it easier for
you to maintain a proper backup. Making it easy to keep the computer
backed up helps assure that you will do it consistently.
BACKUP STRATEGY
When to Backup
How often should you back up your computer? Daily? Weekly? What should you
back up? Everything? Only things that have changed? Where should you store
your backups? On site or off site?
The question is not unlike asking how secure a lock should be. The answer
for a retail business is different from a bank; they are both different
from a household.
A normal home computer for personal use should probably be backed up
weekly, with a copy moved to an off-site location every month. A worst-case
scenario where the computer and all local backup copies are destroyed will
mean you lost up to one month's email and accounting. Not that drastic for
a home computer used for personal activities. The tragedy that made you
lose the computer and backups is usually far worse.
A normal business computer has much higher use, may store client data, and
has accounting information for the business. The email will be work related.
Losing a month's work on that computer will be quite expensive. Most
experts recommend daily backups kept local and weekly backups stored off site.
What to Backup
You do not need to backup software you purchased and have the install disks
for. You do need to backup the programs you purchase online and downloaded.
The same is true for the music you download. On your home computer, backup
your photos, email, and home accounting information. Do you create documents
or spreadsheets you do not want to lose? Do you use software to create
calendars or other specialty information? These are all candidates for your
backup plan.
Your local backup might store only what has changed recently. Your off-site
backup should store all of your vulnerable data. To restore, you simply
restore from your off-site copy and then restore the local backups that you
made after the last off-site copy.
OPTIONS - HOW
Automatic Backup
Let's face it, the main reason backup plans fail is because people forget,
get busy, or for other reasons simply don't make the effort. The good news
is that many automatic backup methods are available. Windows XP has an
automatic backup feature. Configure it to run on a regular basis. This is
a very good solution for your local backups. It will perform your backup
at the time and day you select. Set it up to run at a time when you are
not generally using the computer.
Most dedicated external drive backup systems include automatic backup
software. Many of the on line backup companies do as well.
Off Site Options
Many people overlook the importance of off-site storage for your backups.
Even an expert, writing for a magazine, said that his backup hard drive
is the first thing he will grab if his house catches fire. He overlooks
the fact that his plan assumes he is home when the fire starts, and that
he can get to the hard drive safely. It is vital that you store a copy
of your backup off site.
If you own a small business, take the off site copy home. If your business
is at home, consider sending a copy into work with your spouse. You might
also make arrangements with a colleague to swap off site backups.
CD ROM
CD ROMs and DVD ROMs are inexpensive enough to be used as a regular backup
media. This is an efficient way to create your local backups. Store the
work you changed each day on the CD ROM. If your computer's hard drive
dies overnight, you will have yesterday's work saved. Remember that CD
ROM discs are not permanent storage. The data you store there will be
lost after a year or two.
External Drive
If your home or business has a network, your external hard drive may simply
be the server. If you prefer, you might use a dedicated external hard drive.
CNET reviewed the Maxtor OneTouchIII: http://tinyurl.com/ftd4q. Iomega also
makes external hard drives: http://www.iomega.com/global/index.jsp. Their
Zip drives use removable media; nice for the off-site copies.
Online
Online backup services have come of age over the last few years. Early on,
security was a major concern. Make sure you select an online provider that
encrypts your data. Remember, you are relying on others for your protection.
If the online backup company goes out of business, you might not be able to
access your data. Though we have not tested these services, Consumer Search
has a few reviewed a few providers:

Remember, if your business owns a web site, and you are comfortable using
FTP software, you may be able to upload a .zip file to that space yourself.
SAMPLE STRATEGIES
- Subscribe to an online company to make a weekly backup at the end of
the week. Use the Windows backup feature for the daily, local, backups.
- Use the Windows backup feature to make daily backups to a removable
hard drive. Store a copy off site once a week.
- Use your Zip drive for the complete weekly backup. Keep local copies of
recent work on CD ROMs.
PUTTING THE PLAN INTO ACTION
If you have a plan and you are comfortable that it will work, great! You are
set. If you still have questions, review the sources listed below.
The next important step is to test your backup on a regular basis. There is
nothing more maddening then grabbing your backup, triumphant that your
planning is paying off, and learning that not everything was saved as planned.
Do not format your hard drive and try to restore! Restore to a little-used
computer. Or, restore to a separate directory tree on your main computer.
Make sure all the data you expected was restored.
SOURCES
Be aware that online reviews may be written by anybody. The author may or may
not be unbiased. CNET is one of many reliable sources. A few years ago, they
panned an external hard drive. That review is a few years old, and that
company has probably made several improvements. Still, it proves that CNET is
willing to deliver the bad news when necessary. Look for similar reviews from
any online source.
Use the consumer review magazines at your library. Some are so unbiased that
they refuse to accept advertising. ConsumerSearch On line reviews online
