Normally, you would quiesce/lock your tables, take a snapshot and unlock which would give you consistent backups of your DB. Using snapshots is just much, much faster when dealing with large tables / databases and can be just as safe as using mysqldump. As an example, the backup of a ~200GB InnoDB database using ZFS snapshots is done in ~3 seconds. > > ------------------------------------------------------------------------------ > SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, > Predictive Self Healing and Award Winning ZFS.
