Although your risk of losing data is extremely rare, we want to be transparent about our data loss potential.
In the event of a catastrophic server failure that isn't handled by internal redundancy, the average potential data loss window is 30 minutes (with a maximum of 1 hour). The chance of this occurring is low, but possible, and the only data subject to loss under this circumstance would be data created or modified within the past hour.
In the event of a regional catastrophe that destroys our primary datacenter we would have an average data loss window of 4 days. The chance of this occurring is extremely low.
