Your laptop or computer data is probably very important, however,
you might not realise this until it is lost owing to a virus or faulty
hard disk drive etc. Programs can normally be replaced but data cannot
unless a back up is available!
If a computer is networked to
another computer or laptop then it is quick and easy to save data
between each. Care needs to be taken not to have one machine
accidentally overwrite the other's data. If your computer is stolen or
gets a virus then the data will be lost, so this method of back up will
not be suitable for all users.
The quickest way to back up data is
to save it to an USB RAM drive. This is quick and simple but has many
reliability disadvantages. If you are using an USB RAM disk to back up
your important data there's a high possibility that it will at some
point be lost. USB RAM drives are easily broken by careless handling or
they just fail from electronic component failure. So just use an USB RAM
disk to relocate data between computers and not as a reliable data
store.
Many computer users use an external USB hard disk to act as
a back up for his or her data. They normally leave the drive
permanently connected to the laptop or desktop pc; backing up the
important data infrequently. Again this is not a very reliable or safe
store for your important data. An external hard disk drive is very
easily damaged if knocked or bumped when operating; so the data may not
be recoverable whenever a restore is required.
Most home computer
users will find that DVDs and CDs offer the best all round method to
back up their data, whether its pictures, music or word processing data.
Back up takes slightly longer than by using an USB RAM drive or
external hard drive but it is much harder to break or damage optical
media such as a DVD or CD disk.
Consideration should be given to
the regularity of data back up based on how much the computer is used.
Select which files you are going to back up and when you will be backing
them up. The simple rule is; imagine that your data had been lost,
would you be happy spending that amount of time again repeating the data
previously created and lost. Ensure you date, time and record the
contents to each DVD or CD and store them away from the computer.
Whatever
method of back up you adopt you are likely to only know if it has
worked correctly once you attempt to restore your data back to the PC or
laptop. It is worth spending some time trying to recover your saved
data to a different PC or laptop making sure that your pictures, music,
letters, emails etc are being saved correctly, if not you can go back
and alter your back up methods ready for the time that the data is lost
for real.
