Think you need to check paths for sites.
Your top level domain: cifprodolfoucha.es gets forward to a www.tld site which is a WordPress.
Your moodle is in moodle.tld.
So for consistency, that might be in:
/var/www/vhosts/moodle.cifprodolfoucha.es/ - the htdocs/ directory there contains the moodle code.
moodledata being in /var/www/vhosts/moodle.cifprodolfoucha.es/moodledata/
and inside there one has filedir, sessions, cache, temp, etc.
One should also see a temp/backup/ directory - where backups are built.
If the above is correct, you need to adjust the path to the designated directory where the autobackups of courses are stored. Moodle will not create that designated directory. You have to do that and make sure ownerships/permissions are set to where the user under which the moodle runs can write to it.
Also suggest using lower case letters for 2 reasons: consistency and the fact that Linux is case sensitive.
