Which of the following backup types backs up files that have been added and all data that have been modified since the most recent backup was performed?
performed.
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.
