Now there is no
excuse for not having a Computer Backup!
This article explains what a (PC
or Laptop) Computer Backup is and how it can now be done quickly and easily and
hence why there is really now no excuse for not having a computer backup.
In this article having a Computer
backup means taking a copy of all of your software and all of your data held on
all of the hard drives inside your PC. Having a full backup of this type means
that should any or all of your hard drives fail or your computer is stolen, you
still have a complete copy of everything that was on your computers hard drives.
Hard drives are very reliable,
but they can go wrong. Also viruses can corrupt the data on your hard drives.
If and when a hard drive problem occurs you will be glad you took the trouble
to keep a full system backup. The alternative is reloading and configuring all
of you software again and then there is the more difficult problem of all that
lost personal data such as emails, documents, spreadsheets, PowerPoint presentations,
Music, Videos, Photos etc.
In the past computer backups
would have been difficult and time consuming as they might have involved using
a lot of floppy disc. Alternatively you could have gone for either an internal
or external Tape Backup unit. A tape backup would do the complete system backup
for you, but it might take several hours to backup everything on a system containing
perhaps only many megabytes (MB) of data, but systems today often have
gigabytes (GB) of data. (Note, 1GB is 1024MB i.e. over a thousand times
bigger.)
One method to backup your
complete system these days is to use a DVD writer, if your computer system
contains a suitable DVD drive. You can buy software such as
Norton Ghost 14.0 or the Acronis True Image 11 Home software (see below) that will backup your complete
software and saves it to the hard drive in a number of compressed large files.
Usually two of these large files can be saved to a 4.7GB DVD. So if your full
system backup produced eight of these large files you would then have to save
these files to four DVDs. All this can be done, it just takes time and effort
and a collection of rewritable DVDs. You must also remember to do this at
regular intervals, and to keep 2 or 3 sets of these backup DVDs, so that you
are never overwriting your current backup disks. However, there is now a better
way, and the next method is why there really is no excuse for not having a
computer backup.
You can now get external hard
drives that can simply be connected to your computer (PC or Laptop) via
connections such as the USB connector. These external hard drives can be used
to store even more data, but another very good use for them is as backup
devices. When you purchase one of there external hard drives it may well come
with software that allows you to do full backups as described above. These
backups can be done easily and quickly in one step as all of your software and
data is stored to compressed and possibly encrypted files on the external hard
drive. Encryption of these backup files on the external hard drive is a very
good idea as it means any sensitive personal data that is backed up is secure,
just in case this external hard drive is stolen.
If you purchase an external hard
drive that does not come with its own backup software then all you need to do
is purchase the same type of backup software that was mentioned above when
describing backing up to DVDs, but in this situation the software will simply
backup directly to the external hard drive eliminating the need to copy files
to DVDs.
So now you can do full backups
easily and quickly at regular interval. There is however, another very useful
feature that should come with these types of backup programs and that is to
specify specific directories that you want monitored and if any file in these
directories is updated or a new file is created then these files would be backed
up immediately/dynamically to the external hard drive.

So for example on a Windows
system you might specify that your “My Documents”, Desktop and Favorites
directories be backed up dynamically. If you then created a new document and
saved it in the “My Documents” directory a backup would also be saved to the
external hard drive. If you then updated this document and saved it, the
software would automatically backup the file again, possibly giving it a
version number on the external hard drive so that if need be you could go to
the backup and choose from a list of backed up copies of the same file. This
could be useful if you deleted something for example from a saved Word
document, but then later wished you still had that content, in which case you
could go back to the older backed up version and retrieve the deleted text.
One other thing to consider is
that if you keep your external hard drive permanently connected to your
computer there is the possibility that a virus could corrupt this hard drive or
if your computer is stolen the external hard drive may also be stolen. To guard
against this situation you could also do the DVD backup strategy as described
above occasionally, or you could invest in a second hard drive that is only
used for the full backups and disconnected and stored somewhere safe between
backups.
If you decide to only connect
your external hard drive to you computer when you do a full system backup, you
could use the same external hard drive to backup any other computers you have,
assuming the external hard drive has the storage capacity.
You may well have paid hundreds
or even thousands of Dollars/Pounds etc for your computer hardware and
software. You will have spent many hours configuring and adding data to your
system in terms of documents, spreadsheets, music, photos, videos etc. So if
you take all of this into account and look at the relative cost of purchasing
an external hard drive just for backing up you system, you should now agree
that there is no excuse for not having a Computer Backup. Click here to go to the External Hard Drive/Backup section of our USA Shop for an extensive range of External Hard Drives and Backup software.
