mylvmbackup - a utility for creating MySQL backups using LVM snapshots

-
mylvmbackup is a tool for quickly creating backups of MySQL server's data files. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, makes an LVM snapshot of the volume containing the MySQL data directory, and unlocks the tables again. The snapshot process takes only a small amount of time. When it is done, the server can continue normal operations, while the actual file backup proceeds.

--queue
specifies which queue(s) to delete from, and defaults to all queues.
--orig
specifies that only recipients with the MAIL FROM address be delete…
