And here is why you should ALWAYS backup!
TL;DR: A startup goes el cheapo on a $5 Digital Ocean droplet, hardware node has a RAID 5 dual drive failure, Startup loses VPS but has backups, gets $500 from Digital Ocean and still bitches about it.
We have recently launched Listboard.it on a single instance in DigitalOcean to start contacting people who had too many tabs opened on their browser and were interested on a solution. We received over 240 invitation requests and accepted some to start experimenting with it. Our active users were few so one instance was more than enough. [...] Our server was dead. Just like that.
Altough, quite nice of Digital Ocean to credit $500. They are not obligated to do so.
