Error with xtrabackup8 source: unknown argument for target directory

[petecooper]

Hello.
I'm running an hourly backup job with mysqldump and xtrabackup sources. The xtrabackup source throws an error, while the mysqldump source completes successfully. The backup job runs as root.

It may be that the target directory needs a --target-dir prepended so the argument is recognised.

This is my syntax:

        <backup name="dbname database xtrabackup gzip 10-hourly">
            <source type="xtrabackup8">
                <option name="databases" value="dbname" />
                <option name="host" value="127.0.0.1" />
                <option name="password" value="dbpass"/>
                <option name="user" value="dbuser" />
            </source>
            <target dirname="/mnt/turtle_backups_01/backups/phpbu/textpattern.com/forum/10-hourly/database/" filename="forum.textpattern.com_xtrabackup_10-hourly_%Y%m%d%H%i%s.sql" compress="gzip" />
            <cleanup type="quantity">
                <option name="amount" value="72" />
            </cleanup>
        </backup>

This is the output.

I would be grateful for any guidance. Thank you.

Doesn't work for me, too.
It seems that the Executable wrapper does not add --target-dir before the backup target directory argument.

See https://docs.percona.com/percona-xtrabackup/innovation-release/create-full-backup.html
