Preface for this response .... you might eventually need to find another hosting provider. I have seen a hosting provider that had inode limits which did provide a 'special package' for installing a Moodle to get under their inode limit. That package removed behat testing and some other meant-for-developer tools that come with the typical moodle code.
*BEFORE* thinking about that (one seriously cripples Moodle), look else where first.
Example: got any courses not active (hidden)? Might consider attempting backup of those, download those backups, then remove them.
How many backups of courses do you have?
Are you running Autobackups? Might have to turn that off and find an alternative to backups of courses.
Are you using videos/audios in courses where the videos/audios are stored in Moodle? Might look into hosting those in a repository outside of Moodle where one could simply link to them.
Bascially, you are looking for anything that adds to the inode (which is everything really), that could possibly be hosted else where and linked to.
But .... think your 'best' option is to seek a hosting povider that is more 'moodle friendly'! ;) Moodle, now-a-days, only grows .... it doesn't get smaller.
