MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -This includes files, folders, SaaS applications, hard drives and more. The highlight of a full backup is the minimal time it requires to restore data. However, since as everything is backed up in one go, it takes longer to backup compared to other types of backup.

Detailed explanation-2: -The Incremental backup type includes all new and modified files since the last full, differential or incremental. It is the smallest backup type. When you need to restore an incremental backup, it will take longer as all backup versions since the last full to the latest incremental will be restored.

Detailed explanation-3: -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-4: -A full backup takes the longest time and the most space to complete. However, if an organization only uses full backups, then only the latest full backup needs to be restored. Any backup that uses a differential or incremental backup will first start with a full backup as its baseline.

Detailed explanation-5: -Data restoration speed With that in mind, differential backup recovery requires fewer steps than incremental recovery, so it will take less time. Restoring from an incremental backup is more time-consuming because it depends on multiple backup copies being restored.
