Backup
Backing up something is making a copy of any data so that the copy can restore the original data after a data loss. A backup is the next opportunity to save your data in case of data loss such as in a hard drive crash. Some examples of things you can back up something on are hard drives, floppy disks, CD-ROM's, flash drives, etc. Western Digital has recently created hard drives compatible with Macs. Their new hard drives have amazing memory capacity, including a mirror 2 terabyte hard drive which saves the information on both 1 terabyte hard drives. This way, if one of the hard drives crashes, the other one has all of the information and nothing will be lost.
