MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Incremental backups take the least space and time to perform than differential and full backups, but it’s the most time-consuming out of all of the methods to restore a full system.

Detailed explanation-2: -The most common backup types are a full backup, incremental backup and differential backup. Other backup types include synthetic full backups and mirroring.

Detailed explanation-3: -A full backup is the process of creating one or more copies of all organizational data files in a single backup operation to protect them. Before the full backup process, a data protection specialist such as a backup administrator designates the files to be duplicated-or all files are copied.

Detailed explanation-4: -A full backup can be either an image copy or backup set. An incremental backup copies only those blocks in a data file that change between backups. A level 0 incremental backup, which copies all blocks in the data file, is used as a starting point for an incremental backup strategy.

Detailed explanation-5: -Incremental backups are completed quickly and require fewer resources. Disadvantage: While incremental backups have the fastest backup time, they also boast the slowest data recovery time.
