--databases option of the
mysqlbackup command lets you back up
non-InnoDB tables only from selected databases, rather than
across the entire MySQL instance. (To filter InnoDB tables,
--include option.) You can
specify a space-separated list of database names, with the
entire list enclosed in double quotation marks, or the
absolute path (starting with a
/) of a file
containing the list of names, one per line.
Some or all of the database names can be qualified with table names, to only back up selected tables from those databases.
If you specify this option, make sure to include the same set of databases for every backup (especially incremental backups), so that you do not restore out-of-date versions of any databases.
