Detailed explanation-1: -A full backup is a complete copy of a business or organization’s data assets in their entirety. This process requires all files to be backed up into a single version. It is the best data protection option in terms of speed of recovery and simplicity because it creates a complete copy of the source data set.

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: -Although full backups arguably provide the best protection, most organizations don’t use them on a daily basis because they are time-consuming and often require a lot of disk or tape capacity.

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: -Example of a full backup On Tuesday, the entire directory of folders and files on that drive will be copied. On Friday, any new files added to that drive will be copied and all the existing directory from before will be copied again.
