KembaraXtra-Computer Terms – back up:
Back up refers to the process of creating a duplicate copy of a program, disk, or data so that it can be restored if the original is lost, damaged, or corrupted. This duplicate copy serves as protection against data loss caused by hardware failures, software errors, or accidental deletion. In another context, to back up may also mean returning a system or database to a previously known stable state where the information is complete and consistent. This restoration helps ensure that systems can recover from errors without losing critical data.
