mylvmbackup is a Perl script for quickly creating
backups of a 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. The actual backup can be
performed by using tar, rsync, or rsnap.
