I've had a DO mistake take down my site before, and when it was brought back up it had been reverted to several months prior. DO support was at a loss as to why this would have happened. I tried to restore from DO's backup service, but their backups had apparently stopped running several months prior as well. This was a major issue and could have easily been the death of my company, all because of a DO glitch.

But it wasn't, because every night I run a PG backup and copy it to AWS S3. I just had to download the backup from the other cloud vendor and restore it on my DO server.

Did DO fuck up? Yes. Did it cost me downtime? Yes. Was I mad? Yes, and I still am. But I still do business with DO because it costs ~half the price of a comparable EC2 instance, and writing a 10 line bash script to move my database backups to another cloud vendor isn't that hard. Storing that backup on S3 costs pennies per month.

I don't see "I've never run a business before" as a valid excuse, nor do I see "the cloud vendor is better equipped to handle backups" as a valid excuse. When it comes down to it, you are solely responsible to your customers. They're not going to care whose fault it was, because it was your fault.

Don't trust any of your vendors.
