I've got a couple of databases with small core tables but large cache tables, which I can easily rebuild if lost. This patch provides a new option to automysqlbackup of TABLEEXCLUDE. TABLEEXCLUDE should be a space-separated list of tables in the format DBNAME.TABLENAME, e.g.:
automysqlbackup will then pass these listed tables as mysqldump --ignore-table options when doing the backup, thus excluding these particular tables from the backup.
