Detailed explanation-1: -This type of backup involves backing up data that was created or changed since the last full backup. 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.
Detailed explanation-2: -Incremental backup: Backs up all files that have changed since the last backup occurred.
Detailed explanation-3: -Incremental backups Because an incremental backup will only copy data since the last backup of any type, an organization may run it as often as desired, with only the most recent changes stored.
Detailed explanation-4: -Each backup program has its own approach in executing the backup, but there are four common types of backup implemented and generally used in most of these programs: full backup, differential backup, incremental backup and mirror backup.
Detailed explanation-5: -A full backup of a data file includes all used blocks of the data file. 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.
