Incremental backup backs up files that are created or changed since the last full or incremental backup. Incremental backup provides a faster

method of backing up data than most other backup methods. Restoring data from an incremental backup requires the last full backup and all

subsequent incremental backups. Incremental backups must be restored in the same order as they were created.

If any incremental backup in the incremental backup set is damaged or becomes corrupt, the data backed up after corruption cannot be

restored.

Answer option D is incorrect. Full backup, also known as normal backup, involves backing up the entire hard disks and files of a machine.

When the full backup type is set up, a user should choose which files, folders, and hard disks are to be backed up. After a full backup is

performed, all archive bits are reset to 0.

Answer option A is incorrect. Differential backup backs up files that are created or changed since the last full backup. It requires minimum

space to backup data. Differential backup requires only the last full backup tape and the last differential backup tape to restore data. It is

faster as compared to full backup.

Answer option C is incorrect. There is no such type of backup as daily backup.
