I agree if you want to optimize your db in lieu of deleting posts.
And making a backup prior is also important.
Either way you go.
Just bear in mind that the easy way backups normally will fail with a large database.
such as phpmyadmin or the built in backup with UBB.
Especially the posts and topics tables
