Fast, Reliable, Proven transactional storage for MySQL
Hot Backup
InnoDB Hot Backup is the ideal solution for online backups of InnoDB tables in MySQL—and for setting up replication. It allows you to back up a running InnoDB database under MySQL without setting any locks or disturbing normal database processing. You get a consistent copy of your database, as if the copy were taken at a precise point in time. InnoDB Hot Backup is also the ideal method of setting up new slaves if you use the MySQL replication on InnoDB tables.
See this page for a list of InnoDB Hot Backup features and a list of supported of hardware and operating system platforms. For more detail, see the InnoDB Hot Backup Manual (HTML) (PDF).
InnoDB Hot Backup is licensed on a per-server basis, on annual and perpetual terms, as described here. Support is available on an annual basis, under these terms.
