Maybe this is the reason, (from DigitalOcean):
Backup
User is solely responsible for the preservation of User's Data. Even with respect to Data as to which User contracts for backup services, DigitalOcean shall have no responsibility to preserve Data, the service is provided as is, without warranty.
That is pretty much the case with every VPS provider in my experience. Many will make best efforts but hardly any will offer any garantees so officially distater recovery is your responsibility not their's.
