Abstract
This chapter discusses the backup form of protection from accidental and deliberate loss of data. Backup software consists of two main parts, normally known as backup and restore. Backup is the process of making a copy of all or part of a disk. Restoring is the process of extracting the data from the backup in the case of loss of the original copy of that data. A full backup is just as the name implies; every file on a disk or every file in a specified set is backed up. An incremental backup is quicker. It backs up only those files from the specified set that has been altered since the last full backup was made. Perform a full backup wherever possible, and use incremental backups sparingly. There are many types of media onto which backups can be made. It is fairly common for a user to back up one part of a hard disk onto another part of the same hard disk. Floppy disks are the most frequently used backup media on personal computers (PCs).
