There are many different ways how to store backup copies. The safest way from information security awareness viewpoint, of course, is save these copies on external storage devices and put it as far as possible away from your office.
Here are some devices from which you can choose the best for your backup copies!
✗ Floppy Disc
A floppy disc is a data storage device that is composed of a disc of thin, flexible ("floppy") magnetic storage medium encased in a square or rectangular plastic shell. Floppy discs are read and written by a floppy disk drive or FDD.Capacity: 1,44 MB (3½-inch disc), 1.2 MB (5¼-inch disc)Problems: There can be saved only low capacity files! To make backups for all files you need hundreds of floppy discs! Sometimes they just broken and all information on them lost!
✗ Zip Disc
Similar to a floppy disc, but slightly larger. Cannot be used in the same slot that is used for floppies, and also higher capacity Zip discs must be used in a drive with at least the same capacity ability. Capacity: 100MB – 750MB
Problems: Discs are inconvenient for use because there are different size of discs and also different size of disc drive! They also not so diffuse as other storage devices!
✗ CD-RW
Short for CD-ReWritable disc, a type of CD disc that enables you to write onto it in multiple sessions. CD-RW media can only be written in a CD-RW recorder, not in a simple CD recorder, though a CD-RW recorder can also record standard CD-R discs.Capatity: up to 700MBProblems: You need to buy a CD-RW drive if your computer doesn't come with one, but in nowadays most of computers include this drive! CD discs is easy to damage!
✗ DVD-RW
Short for DVD-ReWritable, a re-recordable DVD format similar to DVD+RW. The data on a DVD-RW disc can be erased and recorded over numerous times without damaging the medium. Capacity: up to 4,7GB Problems: You need to buy a DVD-RW drive if your computer doesn't come with one! DVD discs is easy to damage!
✗ USB Flash
A small, portable flash memory card that plugs into a computer’s USB port and functions as a portable hard drive. USB flash drives are touted as being easy-to-use as they are small enough to be carried in a pocket and can plug into any computer with a USB drive – you don't need special recorder device.Capacity: 128MB - 8GB Problems: Because of there size USB flash is easy to misplace! Keep this device with backup copies in safe and, for you, well known place.
✗ Removable Hard Disc
A type of disc drive system in which hard disc are enclosed in plastic or metal cartridges so that they can be removed like floppy discs. Removable disc drives combine the best aspects of hard and floppy discs. They are nearly as capacious and fast as hard discs and have the portability of floppy discs. Capacity: up to 20GB
Problems: All information are saved to one device, so if something bad happen with this one device, all information also is endangered! So better make more than one backup copy.All devices have some problems, but if backup copies are make in right way and after that keep in safe place, you have really good chances recover your information in emergency condition!!!
