If the wikis have not just separate PHP, but have that because they are
also different versions of the Mediawiki software, then simply copying
the database and images director tree may not work.
Between major revisions at least, there should be expected to be changes
to the DB. I have also run into grief when our hosting service
discontinued support for older versions of PHP that were required for an
older version of Mediawiki.
You would be advised to have both wikis at the same version of software.
If you do this then the procedure Dave Humphrey outlines may be sufficient.

I don't write these requirements, I just try to comply.
We have two wiki installations named "spw" and "spw_public" that have
slightly different PHP code sets. They live in different URLs. We want to make the
display contents identical. The "spw" can be edited; the "spw_public"
is read-only. These have separate underlying databases and images collections, etc.
The "spw" will always be the canonical source. The "spw_public"
should look the same to site visitors, but it does not need to have any revision history.
What would be a good way to "sync" them? Is there a standard process for
backing up and restoring a mediawiki installation, so that I could backup "spw"
and restore it to "spw_public?"
Thanks and regards, Ray

Assuming you want to copy the database and images from "spw" to
"spw_public" you could do:
- Backup Database:
mysqldump --opt -u username -p spw > spw,sql
- Copy Database:
mysql -u username -p spw_public < spw.sql
Note that these assume your database names are "spw" and
"spw_public". The
time this takes depends on the size of your database. For example, our 15GB
MediaWiki database takes about 15min to backup and 1 hour to restore.
For copying images you can do:
rsync -av /path/to/spw/images/ /path/to/spw_public/images/
If you want an exact copy you can add the "--delete" option to rsync to
delete files in "spw_public/images" not found in "spw/images". If you
don't
have many images being uploaded this should be pretty quick as it only
copies any new/updated image file.
