What is incremental backup?

Rating:

An incremental backup backs up files that have been changed or created since the last normal or incremental backup. It takes the backup of files of which the archive attribute is set. After taking a backup, it clears the archive attribute of files. An incremental backup is the fastest backup process. Restoring data from an incremental backup requires the last normal backup and all subsequent incremental backups. Incremental backups must be restored in the same order as they were created.

Note: If any media in the incremental backup set is damaged or data becomes corrupt, the data backed up after corruption cannot be restored.
