How to do backup for my computer data

A wide range of technology solutions are currently available for backup. Most commonly used backup media are as :

Use Tape for Backup : A tape is a sequential storage medium used for data collection, backup and archiving. Like videotape, computer tape is made of flexible plastic with one side coated with a ferromagnetic material. Tapes come in reels, cartridges and cassettes of many sizes, shapes and capacities. The major drawback of tape is its sequential format. Locating a specific record requires reading every record in front of it or searchig for markers that identify predefined partitions.

Use Hard Disk for backup : The primary computer storage medium, a hard disk (often called a disk drive, hard drive or hard disk drive), is a magnetic disk that generally resides permanently in the drive. Data (i.e. files such as email, spreadsheets and documents) is stored on the the hard disk as a collection of bytes. Hard disks provide relatively fast retrieval because they rotate constantly at high speed.

 Use Floppy Disk for Backup : A floppy disk is a soft magnetic disk contained inside a small ircular piece of metal-coated plastic. Unlike most hard disks, floppy disks (often called floppies or diskettes) are portable, because you can remove them from a disk drive.

Backup to DVD : DVDs, or digital vesatile discs, were originally used predominantly as a storage medium for movies but are now commonly used as a general storage medium. they look and operate similarly to a CD-ROM, but they have a much greater storage capacity (tyically 4.7GB, but up to 8.5GB for dual sided disks).

Backup to removal Hard Disk : A removable hard disk, also called a "Removable Rigid Disk " is similar to the fixed hard disk in a computer but housed in a plug-in cartridge and can be removed much like a tape, allowing data to be taken out of

the drive for alternative backup media. Rugged, removable disk media offers increased portability and durability over standard USB- based hard drive storage that may be faster and less expensive when compared to tape storage alternatives, although they do not yet provide the large capacities available on tape.
