Editing Guide to Nanites (section)

==Cloud==
Nanite swarms can be set with a Cloud ID. If so, they will, every 30 seconds, copy the programming of the Cloud Backup with the same ID, if it has been set.
Cloud backups are controlled by Cloud Control Consoles. They can create new backups (with codes from 1 to 100), as well as upload programs from a disk into the selected backup.
Cloud control consoles also serve as storage, meaning that if they're disabled they will no longer sync with connected nanites, and that if all cloud consoles are destroyed, all backups will be lost.

Cloud synchronization has several benefits over direct chamber programming: it can update programs without a second person to operate the chamber, it will reset programming in case of tampering or data corruption, and can be updated remotely by a second person. Of course, the last part also makes it very risky, since anyone could upload malicious programs at any time if they have a console to do it with.
