MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -To put it simply, a full backup is done initially, and then subsequent backups are run to include all the changes made to the files and folders. It lets you restore data faster than full backup since it requires only two backup components: an initial full backup and the latest differential backup.

Detailed explanation-2: -Full Backup But it’s also the quickest to restore from because all the files you need are contained in the same backup set. Full backups on a regular schedule require the most storage out of each method.

Detailed explanation-3: -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.

Detailed explanation-4: -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-5: -Incremental Backup Only the recent changes (increments) are backed up, consuming less storage space and resulting in a speedy backup. However, the recovery time is longer since more backup files will need to be accessed.
