The nabi 2S has nabi Cloud as part of the nabi Sync application. nabi Cloud is an easy way of transferring files from the computer to the tablet, and back up the tablet’s files on the computer. Being able to backup files is an important thing, these days, so that content is never lost.
The nabi Cloud settings are altered in Mommy/Daddy Mode, where you can password protect the contents and set the local storage. The data in the nabi Cloud requires the tablet to be connected to WiFi in order to access it.
The nabi Cloud both reduces the chances of precious files being lost, and makes more storage available, as long as the tablet is connected to WiFi and the computer on which the Cloud is setup is on.
