How to backup files
Level of difficulty:
Information, data or whatever, needs to be stored in files for future reference on the computer. So one should be satisfied and relaxed at the end of an exercise. The important data, which may have taken hours to compile, once it has been saved, is now stored safely for all future reference. Right? Wrong!It is very important to go one step further.A back up, consisting of a copy or copies of all that has been saved, needs to be saved so that if there is a hard drive crash or any other disasters, including virus attack, which seriously infect the whole system of the hard drive’s file. All is not lost. Therein lies the necessity of creating back up files. Concisely speaking, to back-up means to make spare copies of original files and keep them separately from the original files in storage. Other reasons can be when the operating system fails and if the software has been installed badly, that can cause disasters when the question of recovering the files comes up.
