Few days back I blogged about the spirit with which BCP or DR should be planned. Continuing on that here are two recent whitepapers published by Amazon and Microsoft on utilizing cloud as DR environment.
Amazon
This paper talks about how Amazon’s AWS can be used as a DR environment and how various AWS services can play role in that including S3 and EC2.
It also includes backup and restore.

Microsoft
Microsoft’s paper takes more holistic approach which includes how Windows Phone can participate in an event of DR.
