Backup failure on Ubuntu

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?

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.
