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.
