Why Backups are important.
Taking backup regularly is very important.Your data may become corrupt
because of hardware failure like hard disk crash, virus attacks, corruption
in file allocation table due to power failure etc. You may even lose data
because of mistaken deletion of files or mistaken format of Hard Disk. In
all such events, you will be put to great hardship, if proper backup is not
available.
You must take backup on some external media like pen drive, CD etc.
Taking backup on the same hard disk has no value in case of hard disk
crash or some other fault in hard disk.
It is further advised that backup should be kept at some different
place/building.
Backup should be taken at least once in a day. The frequency may be
increased depending upon the work load of your company.
