All data is backed up once a day, unless there are major infrastructure changes, in which case it is backed up on the spot. Our databases are backed up once an hour and immediately synchronized to a secure offsite storage. (We back up, a lot!)
In case of emergency, out ETA restore time is of 4 business hours. Thankfully we back up often enough to be able to rollback a working version while we figure out what went wrong. System Status updates are posted by our Support Team on http://support.amilia.com.
