Trying to backup a MYISAM only database using this:- innobackupex --defaults-file=/etc/mysql/my.cnf --stream=tar --user=root --password=whatever ./ | gzip - \>backup.tar.gz and it fails with these messages… InnoDB: The first specified data file ./ibdata1 did not exist: InnoDB: a new database to be created! 110909 11:47:26 InnoDB: Setting file ./ibdata1 size to 10 MB InnoDB: Database physically writes the file full: wait… xtrabackup: Something wrong with source files… innobackupex: Error: ibbackup child process has died at /usr/bin/innobackupex line 336. Can the script only be used with InnoDB tables? TIA Rich ---

It is an InnoDB backup tool that can also back up MyISAM tables. If you have big MyISAM tables, I don’t recommend using it that way (use xtrabackup binary only, not innobackupex, to back up the InnoDB tables). If you don’t have InnoDB tables, don’t use this tool for backups.
