Lesson 3 - - - Backup your hard drive
Automatic, Image, Clone, Online, Incremental
How much data is
on a typical drive:
There are many
protect your computer data from disasters as there are potential
disasters. The amount of data that may be on a hard drive today, often
½ to 3 Terabyte. A TB equals 1,000,000,000,000 bytes of data. One byte
is a single character. One page type written may contain about 2000
characters. It takes 500,000,000 sheets of paper to hold 1 TB. 3,000
sheets of paper is one foot thick. It takes a stack of paper 167,000
feet high or 3.2 miles high to hold all that data.

data is stored on your hard drive
Local Drive (C:) Where your data, programs,
operating system, etc. is stored.
Where accounts are stored.
(your name) Where your files are
stored< style="font-family: Helvetica,Arial,sans-serif;">
Under your name
find Desktop, Documents, Music, Pictures, Videos and other folders
having to do with you. If you backup all the files under User, you have
backed up all of your data and other users on your computer.
Organize the data
on your hard drive
name) folder you will find Documents, Music, Pictures etc. Here you may
set up other folders to place your files into. Folders will help you
organize your files so they are easy to find in the future.
Other folders on
drive, you have no business making any changes to. The Windows folder
contains the operating system for the computer. Changes there may make
your computer inoperative. Program folders also must not be changed in
any way by you.
What can we backup
It's easy to
make a copy of
all your data on another hard disk sitting next to your computer. We
can do this manually using Windows Explorer, using on line service, or
Windows has an automatic backup system that is easy to set up. With
Windows backup or online service, you are depending on others to be
there if and when you need them, do you really have a useble backup?
You do not have control as to how it may be used to restore or an easy
way to confirm the backup really exists.
If we lost the
original data within our computer due to a disk failure, we could still
have our copy.
If the loss is
due to a fire, we probably lost all our data. If we had a fire, we
would have bigger problems than computer data.
If we had
another copy elsewhere, we may still have a backup.
We can subscribe
to an on
line, automatic backup service for less than $100.00 per year. It's
best to maintain a high speed internet connection (DSL or cable) for
this to work well. Using this, you are depending on a company to be
there and able to serve you whenever needed.
We can use a
thumb drive to
easily transfer data or even installation programs onto another
computer but overall a thumb drive is considered temporary storage.
IMAGE or CLONE
Image and Clone
be a very useful tool. It will read one hard drive, bit by bit and
transfer each bit to a second hard drive. The image backup will skip
over all the blank spaces on the drive but a clone will write all data
and blank spots on the drive.
You can end up
with a hard
disk that may be placed in your computer, ready to go just as the old
disk was when the new disk was made. It will boot (start up your
computer), your programs and data is there and ready to go to work.
It may not be
do such a backup every day, week or month, therefore incremental backup
on a regular schedule of your data is in order
and/or servers have the capability to support several hard drives. It
may be set up to have redundancy by having all information duplicated
on 2 or more hard disks. With a RAID system, when a disk fails, you may
remove it and plug in another and the new disk will quickly catch up
and be fully operational.
I personally use
external USB hard drive and copy everything under User on my hard
drive. I also use a thumb drive for short term backup of files I often
work with. My thumb drive may be used several times a week.
Did you get a
with your new computer? Probably not! Most often there is a partition
on your hard drive labeled RECOVERY (D:). It does contain all the
information your computer needs to start up and/or recover Windows in
case you cannot start up your computer the regular way.
If your hard
works after a catastrophe, you may be able to recover Windows but
normally all of your data, settings and installed programs will no
longer be there.
With Windows 7
and 8, while
you were setting up your new computer, you were given an opportunity to
create a boot-able DVD containing all of the information your computer
needs to start up or reinstall Windows.
You can still
create such a DVD if you did not then:
Go to: Control
panel, Recovery, Create a recovery drive. It may be placed on a DVD or
a thumb drive.
What works for me:
I use an
external hard drive of 2 TB with a USB-3 connector. To copy my files
using Windows Explorer.
external hard drive into your computer (USB) and the power cord into
programs on your computer arent using your files, restart your computer
and go to Windows Explorer.
1. The drive you

if it contained data, the folder or file name will be listed in the
2. Create a
folder on the
external drive by clicking “New Folder”, The New Folder will appear in
the right panel and is ready to be named. I use “YYMMDD” as 131211. 13
is the year, 12 is the month and 11 is the day.
3. There is a
arrow next to the external drive in the left panel. Click on the down
arrow and the folder “131211” appears below it. This is where we copy

backup will begin and take from 10 minutes to an hour to complete. The
progress will be displayed on your screen.
