Getting Started with Computer Backup
A Practical Guide for the Everyday
Person
When it comes to protecting our most valuable computer data, most of
do not us
know that we should be making regular backups because a system failure
would cause unthinkable hardship. Do you live through each day without a backup for
your accounting data, customer
databases, digital photos and other data that is important and
irreplaceable? Why do we
work hard to create new information and not take an extra moment to make a
backup copy...just in case? Most people don't know what
to backup, where to backup, what to use to make backups or how to use
them.
Hopefully this will help improve your understanding and maybe even
motivate you to reward yourself with a new backup routine. The first time
you need to restore a lost file or recover a crashed system, you'll be
glad you put forth that little extra effort to backup your data.
Now, let's help you answer some questions and find the best backup
solution for your needs.
Where to
Backup?
In order to have a backup, you must have some type of storage device to
save the backup copies of your data. You have lots of options to choose
from, but each one is a little different, so we'll help you find the
device that will best meet your needs. There are a number of factors
guiding you to select the most appropriate option, but let's just review
the options first.

3.5" Floppy Drive |
Built-in to most PCs |
1.44 MB Removable Media |
$0.50 |
Slow |
Nice for small amounts of
data. Cheap and portable media. |
CD-R/W |
$149 - $299 (Built-in on
many new PCs) |
up to 700 MB Removable
Media |
$1.00 |
Moderate |
Great backup device and
wonderful for making your own music CDs too. Large backups will
require multiple CDs. |
DVD-R/W, DVD+R/W |
$299 - $599 (Built-in on
many new PCs) |
up to 4.7 GB Removable
Media |
$3 - $5 |
Moderate to Fast |
Another great backup device
similar to CD-R/W but with even greater storage space. This media is
more in line with backing up today's average hard drive
capacities. |
Hard Drive (Primary) |
No Additional Cost. Built-In
to ALL computers |
up to 160 GB and growing.
Commonly under 60 GB. |
Fixed Media |
Fast |
Allocate some space on your
current hard drive. Good for recovering files, but not good for
total system failures since your original and backup data are on the
same physical device. (If you have more than one computer networked
together, you can backup data to a different computer over the
network.) |
Hard Drive(Alternate) |
$50 - $599 Can be installed
inside your PC or an external device. |
up to 160 GB and
growing. |
Fixed Media. The device and
the media are one and the same. |
Fast |
New hard drives are cheap
and somewhat easy to install if you know what you're doing. External
drives save installation problems, but cost a little more. |
ZIP® Drive |
$149 (rarely built-in with a
new PC.) |
100 MB or 250
MB |
$10 each Removable Media |
Slow |
This is a floppy on
Steroids. The most popular high-capacity floppy-disk type
device. |
Tape Drive |
$299 - $3000+ |
4GB to 110 GB |
$10 (4 GB) to $100 (110GB)
Removable Media |
Fast |
A great high-capacity
removable media. Generally used by more sophisticated users. |
Internet Backup |
Uses your Internet
connection to send data to a secure remote server |
Unlimited storage
available, but costs and Internet speeds impose practical limits |
Roughly $20/month for 500
MB |
Moderate Depends mostly
on internet connection speed. |
No devices to mess with.
Most people have Internet connections. Data is off-site. |
Printer |
Any printer will do. |
Unlimited pages |
$15 for 500 pages $40
Ink/Toner |
Very Slow |
Now this may seem silly,
but a paper backup is better then nothing at
all. |
What to
Backup?
When it comes time to decide exactly what needs to be backed up,
everyone is a little different. If you can decide what you MUST be able to
recover in the event of a system failure, that can help narrow your
options for selecting a backup device. And if you don't like your options
after deciding what you want to backup, maybe you'll have to change your
expectations to make your options more acceptable.
Here's a few different ways to decide what to backup. What fits you
best?
Type of Backup |
Description |
Best Devices for this |
Comments |
Entire System
(Image-based) |
Protecting your entire
system usually takes more time and larger capacity backup devices,
but it provides a smooth recovery from total system failure. It's
not ideal for occasional file recovery. |
CD-R/W DVD-R/W Hard
Drive Tape Drive |
Also great for making
copies of systems. |
Entire System
(File-based) |
Protecting your entire
system with a file-based technique combines complete system recovery
and individual file restoration from the same program. Backing up
more data will require more time and a high capacity backup
device. |
CD-R/W DVD-R/W Hard
Drive Tape Drive |
Best of both worlds. |
Data Files Only |
Limiting your backups to
just your critical files gives you the essential protection you need
and gives you the broadest options in terms of backup devices that
you can use. |
ALL Devices |
Initial setup takes a
little time, but saves time and money with each
backup. |
When would you like the
backups to run?
This is a simple question of whether or not you'd like to be involved
in every backup. Scheduling your backups could help you remember to do
backups and keep you disciplined enough to continue backing up. If you're
comfortable enough to remember doing your own backups, than a backup
scheduler won't be as important for you. Keep in mind, if you are backing
up to a removable device and the amount of data that you are backing up is
larger that the capacity of your backup media, you will need more than one
piece of media to complete the backup. This is called "spanning" and most
likely requires that you physically insert a new piece of media when
necessary. This could put a damper on things if you were planning to run
an unattended scheduled backup. To avoid spanning, you have to use one
piece of backup media that has enough capacity to store your entire
backup.
- Scheduled Backups - The backup software allows you to select
a backup schedule, such as 9 P.M. every weekday, to automatically run a
backup of your files.
- Manual Backup - This means that you'll run the backup
yourself without any reminders.
Simple Backup Management
Tips
Once you've established a backup routine, it would be wise to keep
these few safe backup tips in mind.
- Test your backups!
When you think of it, try restoring a
few important files from your backup, just to make sure that your file
selections and your backup media are performing as expected. We've heard
plenty of horror stories that could have been avoided by occasionally
running this simple test.
- Check your backup logs.
Most backup software provides a
log file after each backup. Log files can be somewhat complicated to
read, but you can quickly scan it to look for any problems. If you see
words like "Error", "Failed", "Unable to...", etc. you should take a
closer look. If you have problems contact our technical support...It's Free!
- Keep a backup off-site!
We all hate to think of it, but
things like theft, fire and other natural disasters can destroy your
entire work area. Taking your backup media off-site is a good idea.
Storing your backups in a safe deposit box is great, but an off-site
dresser drawer would suffice. To avoid the hassle of transporting media
off-site, you might want to consider BTR Services Online Backup service.
Your data is transmitted over your Internet connection to a private and
secure off-site storage area.
