Explanation

An incremental backup only backs up files that have changed since the last backup, whether it was a full or an incremental backup. Therefore, an incremental backup file may require another file to restore data, depending on the sequence of backups. A full backup backs up all files and does not require any other file to restore data. A snapshot is a point-in-time copy of data that does not depend on other files. A differential backup backs up files that have changed since the last full backup and does not require any other file to restore data.
