Backup is actually a copy of one or more files. These are made on the basis of an alternate if in some circumstances the original data is lost or becomes unusable.

Backup is a very important computer term that you must know about.

For example, maybe you have several copies of any important papers your hard drive be sure to attribute the backup files but in case it stops working hard drive all of your Backup File will be deleted . At the same time it would be better if you keep backup of those files in your USB flash disk or in cloud storage . With this, all those files will remain protected.

Hard drives are made in such a way that they run smoothly for many years without crashing. But like other electronic devices, they are also not completely immune to problems.

As these are not solid state devices , hard drives rely on them to access the data above the moving parts , which can be malfunctioning and make your data unrecoverable. If you do not believe how light these hard drives are, then you can see them in a computer shop near your house.

When you see this yourself, then you will definitely worry about the backup of your data .

At the same time, your files are not destroyed by hardware malfunctions only . Rather, software corruption can also cause damage to your files. Directory structures can also be damaged and can make all your folders disappear in a pinch.

Not only this, files are sometimes deleted from us even by mistake, while sometimes it can also be corrupted by a virus or software attacks. In such a situation, you must have known that there are so many ways through which your data can be damaged or deleted.

This is why it is so important to keep a backup of your data. Many people do not realize the need for backup until a major accident happens to them. When you lose the data of your photos , music, movies , business documents etc. which you cannot recover, then people probably understand the importance of backup.

Now the question arises that how to backup your data?

The best way is to use an external storage device, such as an external hard drive, flash memory device, or another computer. Whereas if you want, you can also create permanent backups using optical media, such as CD-R and DVD-R discs.

It is quite easy to backup an individual file or folder because in this you have to copy files from source media (your computer hard disk ) to the destination (your external hard drive).

But when you have to backup your entire system, in such a situation, you cannot do backup individually, rather you will have to use backup software to backup your data. You will get many such programs for your Mac and Windows which help you by providing facilities of automatic backups and system restore capabilities.

If you have not yet backed up your hard drive, then you should prepare a backup of these data as soon as possible, otherwise there will be no other way than to repent.
