Data backup involves copying files or databases to secondary storage so that information can be restored after hardware failure, accidental deletion or other disasters. Regular backups are essential for organisational resilience. ICT policies usually specify backup schedules and methods. Hence, the practice described is data backup.

Option A:
Option A is correct because backup specifically denotes maintaining extra copies of data for recovery purposes.

Option B:
Option B, formatting, prepares a storage medium for use and usually erases existing data, which is the opposite of preservation.

Option C:
Option C, deletion, removes data and increases risk of loss rather than protection.

Option D:
Option D, fragmentation, refers to data being scattered on a disk, which may affect performance but is unrelated to safety copies.
