It would be very useful to have a mechanism/API allowing backup and restore of the system database to/from the cloud. It could be private cloud storage or iRidium cloud. It would allow to keep the historical data in case server failure or other accidental data wipe. I understand that at the moment it is only possible by manual copying database file between devices/folders, which might be problematic in some cases.
