Where can I find recent / reliable information about what backups are undertaken by Microsoft, which also covers things like frequency, retention periods, recovery etc?

They dont really publish the details anymore. You can find some info in the EO service description documents: https://technet.microsoft.com/en-us/library/exchange-online-high-availability-and-business-continuity.aspx

Here's the relevant info from the old documents (circa 2012, so take it with a grain of salt):

Exchange Online has set an RPO and RTO for client messaging services in the event of a disaster:
•      Nearly instantaneous RPO: Microsoft protects your Exchange Online data and makes a nearly instantaneous copy of your data.
•      1 hour RTO: Organizations will be able to resume service within 60 minutes after service disruption if a disaster incapacitates a hosting data center.
The following conditions apply to service continuity management:
•      Please see the Office 365 Identity Service Description for recovery times and other details related to sign-in and provisioning of new users and new tenants.
•      Client access after recovery from a service disruption typically does not require reconfiguration on the part of Exchange Online subscribers.
•      To achieve the stated recovery times, customer networking infrastructure must honor the DNS record Time to Live (TTL) of 5 minutes. Customers that have customized their client DNS settings and set a longer TTL may experience longer recovery times.
•      After RPO and RTO objectives are met, there is a period of time before full data center redundancy is restored for the service. For example, Data Center 1 fails but services are restored by resources in Data Center 2. There may be a period of time until services in Data Center 2 have service continuity support either by restored resources in Data Center 1 or new resources in Data Center 3. Service Level agreements apply during this time.
