Detailed explanation-1: -During an incremental backup operation, all specified files have their archive bit examined. If the bit is set, the file is backed up, and then the bit is cleared. This backup type is used to back up data that has changed or been created since the last full (normal) or incremental 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: -Incremental backups also back up only the changed data, but they only back up the data that has changed since the last backup-be it a full or incremental backup.
Detailed explanation-4: -An incremental cloud backup stores only data and files that have been modified since the previous backup was conducted. The sole purpose of incremental file backup is to capture any changes that have happened since the last archive.
