Commit all folders and files in a directory using commandline

We are having trouble with having a generalized approach to committing with a batch file using commandline SVN.

We've got a backup script that created a new folder with the current date containing the database dumps of our database. (Yes, we version control our database).

Now how can I use the svn commit command to include all directories that are new in the project?

Is there an approach without using the svn add command?`
