Backup depends both on the software and the hardware used. Backups are frequently made from hard disk based production systems. Before deciding on a backup system, the way in which the system is used and the connections required must be thought of. This will help to identify the most suitable match. There are several types of external data backup devices. Auxiliary hard drives are available in both internal and external versions. Prices have come down over the years as storage capacity has considerably increased.
There are different removable media drives. They include a variety of products that use some type of removable disk or cartridge. Zip drives, offered in desktop and compact versions for use with portables, are the more universal. Zip drives are starting to appear in scanners and printers. Super Disk can read both high capacity disks and floppies you have been using for years.

CD-RW is a drive that writes to a high capacity CD-R (recordable disc) or CD-RW (rewritable disc). It has a lot of storage capacity. DVD (Digital Versatile Disk) is the newest optical recording technology, and it is popular because of the large amount of data that can be stored on each disc. The main problem is its price. Tape backup systems for offices and networks offer a combination of attractive prices, high capacity per tape cartridge, and automated data backup functions. They provide real time hard disk backup and disk imaging. Magnetic tapes and floppy drives are also used for data backup. Floppy drives are a traditional method.
Drive backup creates a backup image of the whole hard disk with operating system, with all user preferences and settings, applications and data files. With the latest drive backup you can create the complete hard drive image without interrupting current activity. It serves to restore data at any time, set up a new hard drive or clone hard drive, schedule the backup process, make differential backups, and use disk image verification and password protection.
Flash drives are used for backup of a small amount of data. Flash drives are also known as thumb drives or memory sticks. Flash drives are small, offer infinite rewrite capabilities, and are easy to plug into any computer with USB port. Data durability is expected to be approximately ten years. They are not subject to damage by magnets.
Most traditional external data backup systems need a data set to be frozen for hours while the complete content of a file system is copied to magnetic tape. Modern techniques use incremental backup forever. Individual data objects are backed up in logical order on backup media such as magnetic tape so that they may be retrieved independently.
