What exactly does the default ibdata1 file store that does not exist in a mysqldump?

I've got a backup/rsync job that stores dump files of a MySQL 5.5 database on a remote server for rotating daily/weekly backups.

However, I am not currently backing up the ibdata1 file itself -- is this a nightmare waiting to happen or are dump files enough?

No, if you are doing proper mysqldumps the information necessary to rebuild the database will be present. You don't have to backup the ibdata1 file.

Proper mysqldumps are comprised of SQL code and all the data necessary to recreate all the tables and their relationships in the database they were made from. – Fiasco Labs Jan 26 '13 at 2:18
