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: -As a result, incremental backups are generally better in the cloud because they typically consume fewer resources. Incremental backups are also smaller than differential backups. With storage space as a big element of cost in the cloud, the smaller the backup, the better.

Detailed explanation-4: -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.

Detailed explanation-5: -How many types of Backup? There are mainly three types of backups: Full backup, differential backup, and incremental backup. Let’s take a look at each type of backup, their impact on data security, and their respective pros and cons.
