I've decided I need to back up my desktop and laptop. My
understandind is that I can do it on either a disk or a hard drive.
First of all, a hard drive *is* a disk.
If by a "disk,: you mean a diskette, or floppy drive, a diskette is *much
too small to be used for backup purposes these days. You would need to use
hundreds of diskettes.
Or if by "disk," you mean a CD, even a CD, while much bigger than a
diskette, is by itself too small for most backup uses today. You would still
need multiple CDs.
As of now, my desktop does not have a CD burner. I don't plan on
install one either.
Why not?
So, what should I do? Should I get an external CD
burner for my desktop (my laptop has one)
If you want a CD burner, it's much cheaper and more practical to buy and
install an internal one. External CD burners make sense for laptops, but not
often for desktops.
and some software like
Ghost, true image or Norton whatever? Or should I buy a hard drive.
If I buy, let's say, a 200G hard drive, could I use it to back up 2
seperate 80G computers?
Yes.
If so, what kind of software would I need?
Or, could I do it with just the hard drive and XP's backup program (I
forgot the name)?
You can use the XP backup program, but it's very primitive compared to
third-party choices. I would recommend buying something better.
Here's my standard blurb on backup:
First of all, almost everyone should be backing up regularly. It is always
possible that a hard drive crash, user error, nearby lightning strike, virus
attack, even theft of the computer, can cause the loss of everything on your
drive. As has often been said, it's not a matter of whether you will have
such a problem, but when.
Essentially you should back up what you can't afford to lose--what you can't
readily recreate. What that is depends on how you use your computer and what
you use it for.
It takes time and effort to backup, but it also takes time and effort to
recreate lost data. If you back up daily, you should never have to recreate
more than one day's worth of last data. If weekly, there's potentially a lot
more to recreate. You should assess how much pain and trouble you would have
if you lost x days of data, and then choose a backup frequency that doesn't
involve more pain and trouble than that you would have if you had to
recreate what was lost.
At one extreme is the professional user who would likely go out of business
if his data was lost. He probably needs to back up at least daily. At the
other extreme is the kid who doesn't use his game except to play games. He
probably needs no backup at all, since worst case he can easily reinstall
his games.
Most of us fall somewhere between those extremes, but nobody can tell you
where you fall; you need to determine that for yourself.
Should you back up Windows? Should you back up your applications? Most
people will tell you no, since you can always reinstall these easily from
the original media. But I don't think the answer is so clear-cut. Many
people have substantial time and effort invested in customizing Windows and
configuring their apps to work the way they want to. Putting all of that
back the way it was can be a difficult, time-consuming effort. Whether you
should backup up Windows and apps depends, once again, on you.
How to backup? What software to use? There are many choices, including the
Windows-supplied backup program. Which choice is best for you depends at
least in part on the answers to some of the questions above.
Finally what backup media should you choose, and how should it be stored?
There are many choices, including CDs, tape, zip drives, and second hard
drives.
I don't recommend backup to a second non-removable hard drive because it
leaves you susceptible to simultaneous loss of the original and backup to
many of the most common dangers: severe power glitches, nearby lightning
strikes, virus attacks, even theft of the computer.
In my view, secure backup needs to be on removable media, and not kept in
the computer. For really secure backup (needed, for example, if the life of
your business depends on your data) you should have multiple generations of
backup, and at least one of those generations should be stored off-site.
My computer isn't used for business, but my personal backup scheme uses two
identical removable hard drives. I alternate between the two, and use Drive
Image to make a complete copy of the primary drive.
