MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Backup applications have long offered several types of backup operations. The most common backup types are a full backup, incremental backup and differential backup.

Detailed explanation-2: -An incremental backup is a backup type that only copies data that has been changed or created since the previous backup activity was conducted. An incremental backup approach is used when the amount of data that has to be protected is too voluminous to do a full backup of that data every day.

Detailed explanation-3: -There are 3 main types of backup: Full, differential and incremental.

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.
