What are Full and Incremental backups?
• A full backup is a complete copy of the specified databases or tables. A full backup can be logical, raw, or snapshot-based. • An incremental backup stores data changed since the last (full or incremental) backup by leveraging MySQL binary logs. When ZRM for MySQL performs an incremental backup, it flushes and saves the MySQL binary logs without a read lock, so it is a “hot backup” with no impact on the MySQL database.
