Your computer hard drive is very important:
Your hard drive is the heart of your computer system. It
contains your Windows operating system, which is the master
control program of your computer. It also contains all of your
application programs that help you do productive things with
your computer. But, most importantly, it contains all the data
files that you create using your application programs. These
data files are the most valuable part of your computer and the
hardest to replace if something should happen to your hard
drive.
Yes, your hard drive will fail on you
someday: Your hard drive is a mechanical device that spins
constantly and is certain to wear out. The life of a hard drive
is only 2-3 years. If you are lucky, your drive may last you 4
or 5 years, but it could go out in just 6 months. It is not a
question of if your hard drive will fail, but it's a question of
when it will fail. All you can do is to be ready when it does
fail by having a copy of all of the files on your hard drive
saved away from your computer. Then you can replace the failed
drive with an empty new drive and put all of the files on the
new hard drive. This lets you be back up and running in a mater
of minutes instead of days or weeks rebuilding your drive. This
process is called backing up and restoring your hard drive and
is the topic of this article.
What files should you backup: One of the
first decisions you must make is what files need to be backed up
to adequately protect you. I consider your data files as the
most important ones to backup. Your data files are those files
that you create using your application programs. If you use
Quicken, then the data file that needs to be backed up contains
all of your financial records entered into Quicken. If you
research your genealogy, then the database of your ancestors
that you've collected for years is the important data file that
must be backed up. If you correspond extensively using E-mail,
then the folders of your E-mail correspondence needs to be
backed up. You should plan on backing up your data files at
least weekly.
The second most important thing to backup
is your entire hard drive and all of the files on it. This
includes your Windows operating system as well as all of your
application programs. By backing up the entire hard drive, you
will not have to rebuild your system from scratch, but will be
able to quickly get your system back up and running again. Some
would suggest that you really don't need to backup your
operating system and application programs because you can always
reload them from the CDs they came on. While this is mostly
true, you need to consider how much time this will take you to
reinstall the operating system and all of the applications you
own. Then, how long will it take you to download all of the
software patches and add-ons that you have added to your system.
Finally, how long will it take you to enter all of the special
settings that you must do to have your system work exactly as
you like it to. To this lengthy time, consider how you can
recover the many programs and files for which you do not have a
CD. I think when you consider all of these factors, you'll agree
that having a backup of your entire hard drive is a wise
investment of your time. You should plan on backing up your
entire hard drive on a monthly basis.
What media is best for backup: The next
question you need to consider is what is the best media to
backup your files from your hard drive. A few years ago, tape
backup systems were the most popular backup media. The only
problem with these tape systems was that they were very slow.
Backing up a 1-2GB hard drive in a couple of hours was
reasonable, but backing up today's 120GB hard drives to tape
would take too long. You would not do it often enough to be
usable. The next popular backup media to come along were the
removable disk cartridge drives. These were much faster than
tape, but the cartridges tended to be expensive. For example, a
40GB hard drive would need 10-20 Jazz (2GB) cartridges to backup
the entire drive. At $100 each, you would need to invest over
$2,000 in cartridges to backup your entire drive. Writing to
blank CDs promises to be one of the best backup media today, but
even the fastest drives are slow and it takes many blank CDs to
backup a large hard drive.
So, what is the best media to backup a 40GB
hard drive today? Another 40GB hard drive! Hard drives are much
faster than tape and are even faster than the disk cartridge
systems. You can backup an entire 40GB hard drive in less than
an hour or so. Since it is fast, you'll tend to backup your
system more often and this means better protection for you. Hard
drives are also very inexpensive to purchase. If you watch
prices carefully, you can get a 120GB hard drive for $99 or
less. I would plan on having an extra hard drive for backup
purposes for each hard drive that you save data on.
What type of backup software is available:
There are two very different backup utilities on the market
today -- File backup utilities and Partition backup utilities.
File backup utilities are by far the most common. These
utilities backup individual files one at a time. They can also
be used to restore individual files to your hard drive. A good
feature of File backup utilities is that they can select
individual files from all parts of your hard drive. This is
great for picking and choosing your important data files to
backup. On the other hand, File backup utilities tend to be
quite slow in backing up your entire hard drive and you would
need to make many extra steps in rebuilding your hard drive
partitions in case of a total failure. That is where Partition
backup utilities have the advantage. Partition backup utilities
backup entire partitions and all the files contained in them.
Some of these Partition backup utilities work at the lowest
hardware level and are very fast. Restoring a partition to an
empty hard drive using a partition backup utility will create
and format partitions as it restores the partition file.
Acronis Corporation has an excellent backup
software package that will easily backup your entire hard drive.
This product is called True Image and has a list price of $50.
Let's take a look at how this utility can be used to backup your
entire system.
Backing up your entire hard drive: The most
important part of your backup plan is to backup your entire hard
drive at least once a month. Having this backup in place will
protect you from a major failure of your entire hard drive.
Using Acronis True Image to backup your entire hard drive you
have two approaches to select from. Let's look at each of these
approaches separately.
The first full-drive backup approach is to
use True Image to copy all of the partitions from your main hard
drive to a backup hard drive. Both hard drives must be installed
on the same computer system to do this approach. Using True
Image's Disk Clone facility, you copy the partitions from your
main drive to the backup drive, one at a time. When True Image
copies a partition, it creates a new partition on the backup
drive, so the drive can be empty of partitions before you start
the process. Also, copying a partition copies not only the
partition, but also all of the hidden files, system files, and
other files contained in the partition to the backup hard drive.
So, when you finish copying all of the partitions from your main
drive to the backup drive, you have an exact duplicate of your
main drive that could be used if your main drive failed.
After copying all of the partitions to your
backup hard drive, you need to disconnect the backup drive and
remove it from your computer system. You should store the drive
away from your computer, so that if anything happens to your
computer, your backup drive will not be affected, too. Once a
month, you'll need to retrieve this backup hard drive and insert
and connect it back into your computer and repeat the backing up
of all of your partitions, then remove it again from your
computer. If something should happen to your main hard drive,
simply get your backup hard drive and replace your main hard
drive with the backup drive, setting it as a master drive, and
you should be able to immediately start your computer and have
it run. To simplify the frequent removal and replacement of your
backup hard drive, you can purchase a hard drive rack mounting
system from your computer store for about $25 that will let you
remove and insert the drive without removing the covers of your
computer.
The second full-drive backup approach is to
use True Image to cross backup one hard drive to another. With
this approach, you install and leave both hard drives in your
computer all the time. For this approach to work, you'll need to
setup a large backup partition at the end of each of the two
hard drives. Acronis Disk Director Suite utility is the best way
to create these backup partitions on your hard drives. Once the
two drives are in place with a large backup partition on each of
them, you can use True Image to create condensed image files of
entire partitions and store them on the backup partition of the
other hard drive.
To make this a little easier to understand,
let's look at a simple example. You have two hard drives and the
following partitions on each of the two hard drives:
Drive 1:
- C: partition (Contains your Operating
System)
- D: partition (A backup partition)
Drive 2:
- E: partition (Contains your Application
Programs)
- F: partition (Contains your Data Files)
- G: partition (A backup partition)
Using True Image, create an image file of
your entire C: partition and all of its contents on your G:
backup partition. Then, using True Image, create an image file
of your E: and F: partitions on your D: backup partition. These
image files represent the entire partition and all of their
active content. These image files can be condensed by 40-50% to
save room on your backup partition. Notice that we save the
images from one hard drive to the other hard drive's backup
partition and visa-versa. Hence, we call this the cross backup
approach.
Once a month, you'd repeat this cross
backup approach from one drive to the other until you fill up
the backup partition. Then you'd delete the oldest image file to
make room for the new image file to be stored in your backup
partition. If either of your hard drives should fail on you, all
you have to do is to remove the failed drive and place an empty
new drive in its place. Then using True Image, you find the
latest condensed image of the partitions on the failed drive on
the other drive's backup partition and restore that image to
recreate the partitions and all of their content on the empty
drive. This lets you be back up and running your computer in a
matter of minutes instead of days or weeks rebuilding your
system. If the drive that failed was your first drive containing
your operating system, that is no problem. You can boot True
Image from a rescue CD or diskette that True Image will create
for you and quickly rebuild your operating system partitions
from the second drive's backup partition.
What if both hard drives fail together:
While it is rare, it is possible for both of your hard drives to
fail at the same time, thus leaving you without either of your
backup partitions to use to rebuild the other hard drive. For
example, your computer could be burned in a fire or taken by a
thief. In these cases, you'd loose not only your main drive, but
your backup images as well. So, you need to make some special
provisions to guard against these situations. I'd recommend that
every 3 months, after you have backed up your partitions using
the cross backup approach, you copy your image files to an
external hard drive or CDs. While this may take a while to do,
it will give you an inexpensive removable backup of your entire
hard drive that you can store away from your computer. I would
repeat this process of creating backup CDs of your entire hard
drive every 3 months or so.
Summary: If you follow the suggestions in
this article, then you will have a comprehensive backup plan
that will protect both your important data files as well as your
entire hard drive. You must make sure that you follow the time
intervals suggested so that your backups are current enough to
be usable. Acronis True Image product, a second hard drive, and
a CD-R/RW drive are all the software and hardware you need to
run this backup plan. A second hard drive and a CD-R/RW drive
can both be purchased for about $100 each. Faster models are
available for only a few dollars more. User group members can
