Backup How To
Once data is lost, it is difficult to recover. Having a good backup
provides you with an important safety net.
Why You Need a Backup
The hard disk is the main storage medium in personal computers. Unfortunately,
hard disks do sometimes fail, or in computer lingo, crash. When a
hard disk crashes, all of your data are in jeopardy. Sometimes information
can be retrieved after a crash, but it is usually an aggravating,
time-consuming procedure that may end in despair.
To backup your files simply means copying files
to a second medium as a precaution in case the first medium fails.
The medium used to
make the copy can be any of a number of different storage choices including
floppy disks, hard disks, Zip® disks, CDs, or tapes.
Backup a Few Quick Files
Some say that the floppy disk is a dying medium. Some computers don't
even come with a floppy drive (although I wouldn’t buy a computer
without one). Floppy disks are an easy way to backup a single file
or a small set of files. Any important file can be copied to a floppy
disk for backup purposes. If you happen to be working on an important
document, you can quickly insert a floppy disk and copy the document
to the floppy to ensure that loss of power, hard disk crash, or another
unexpected calamity won't leave you unprepared.
The simplest way to backup a file to a floppy disk is to use the Save
As choice under the File menu. When you are asked where to save it,
choose drive A. The floppy drive on a single drive computer is always
drive A. Save to a floppy when you are finished with the file and don’t
work on the file from the floppy. You run the risk of losing data if
you edit your files on the floppy.
Programs with Built-in Backups
Some programs, such as Quicken, have an icon that you can click or
a menu choice to backup your data files. You will often have the
choice of saving the files to a floppy disk or other medium that
you have available. This type of backup only makes a copy of your
data. It will not make a copy of the program itself. These built-in
backups are very useful, especially for financial and other important
files.
Backup Media
The first thing that you must decide is what kind of medium to use
to backup your data. While the good old floppy disk is adequate for
copying a few files, floppies do not hold much data. Even if you
backup individual files as you use them, it is good to occasionally
backup all of your files. If you do a complete backup of your hard
disk, you will be able
to reconstruct the entire disk and/or restore any individual program or file.
A complete backup requires a medium that can handle a large amount
of data. Recordable and/or rewritable CD-ROM drives are now one of
the best backup media. Recordable CD’s (CD-Rs) can only write a CD
once, although you can continue to add data to a disc until it is full.
Rewritable CDs (CD-RWs) can write a CD, erase it, and write on it again.
Most writable CD devices come with software that helps you backup your
data. Many CD-ROM drives (the ones that only read discs) cannot read
CD-RWs.
Online Backup Services
Another option currently available is an online data backup, like Connected
Online Backup. These subscription-based backup services allow you
to schedule backups whenever you like. All you have to do is choose
what you want to backup and how often and leave your computer on.
Your computer will connect at whatever time you choose and backup
your files to the Web service's computers. A monthly fee is charged
based on the amount of data you want to backup. Obviously, you will
want to make sure that the company you use for this kind of service
is very good. You are putting your data in their hands, so make sure
that they are using secure servers and encrypting (coding) the data.
You don’t want your data to be accessed by anyone else.
What to Backup
Your hard drive holds three things: the operating system, applications
or programs, and data. The operating system is Windows. Although
you may lose some settings that have been customized, in general
the operating system can be restored from the original CD that came
with your computer. Your programs, again, minus some settings can
also be restored from their original CDs. Your data include all of
the files and documents that you create, the e-mail that you send
and receive, the favorites and/or bookmarks that you use in your
browser, your Internet settings, and all of the photos, graphics,
and other files stored on your computer.
Don't underestimate the importance of your data. It took you time
and, sometimes, money to create the data. You will probably have to
expend a similar amount of time and money to recreate it. If you are
working with “really important stuff,” keep paper copies as an additional
backup.
Obviously, there are many important things to backup. Unfortunately,
Windows does not make this easy. Window 9x keeps all of your documents
in a folder called My Documents, but your Internet settings, favorites,
and other important data are scattered throughout the Windows directory.
Windows 2000 and XP keep things in individual “My Document” folders
under Documents and Settings. Many programs don't use the My Document
folder, so even documents files that you create may be spread about
your hard disk. It’s a good idea to tell your programs to put the data
in a sub-folder of My Documents, if you can.
Tips for Backing Up:
- Test your backups. Make sure that the disk actually contains
the files you think they do. Test your backup by trying to restore
a file
or two.
- Rotate your media. Keep four or five disks, CDs, or sets of
disks for your backups.
Rotate them, using them in succession each time you backup.
- Remember that a disk can wear out after many uses.
After a few months or a year, (depending on how much you use it)
you might want
to replace the disks that you are using with new ones.
- Proper labeling is also an important part of backing up. Be
sure to label your disk with the date and contents.
- Keep all of your program disks together so you can find them
when you need them.
- If you backup only your data, you'll have to
reinstall all your applications in the case of a hard disk crash.
If you have a Zip®,
Jaz®, or CD-R/RW drive, create a disk to hold all the files, patches,
updates, and other things you download. This will make reinstalling
your applications much easier.
- Keep your backups in a safe place. If you consider
your data extremely important, you should keep a copy offsite, in
a safe deposit box, or
another location protected from theft or fire. When you make two
sets of backup data and keep an extra set in another location, you
minimize
the chance of data loss.
Backing up your data makes good sense. It's like buying
an insurance policy. You hope you will never need it, but when disaster
strikes,
that backup will be your most appreciated forethought. Of course, if
your hard drive crashes, there are always data recovery services. They
can be very expensive.
