backup utility Definitions Computing. noun a piece of software that simplifies the process of backing up data; Electronics. A computer program which organizes and simplifies backing-up of files, for instance, by following a schedule, or by compressing the data to economize storage space and time.
An incremental backup is one in which successive copies of the data contain only that portion that has changed since the preceding backup copy was made. When a full recovery is needed, the restoration process would need the last full backup plus all the incremental backups until the point of restoration. Incremental backups are often desirable as they reduce storage space usage, and are quicker to perform than differential backups.
