Thread:Project:Support desk/mediawiki database backup/reply (5)

As I said: You can exclude the content of some tables (objectcache, l10n_cache, externallinks, imagelinks, iwlinks, langlinks), but you cannot exclude the table definitions themselves. This will create some overhead for creating the DB dump with these modifications. And even if you decide to exclude certain tables, you will have to do additional steps to get a running wiki again later; it will then not only be importing the DB and that's it.

This is not worth the hassle.
