			Sugar itself requires only about 40 MB of disk space. Its dependencies will require more or less space depending on the distribution used, OLPC's needs less than 500MB. For Sugar activities, 10-100 MB would be reasonable, plus some hundreds of MB for user data. A backup server is recommended, so users don't need to keep all their data locally.
