How is our data backed-up? Financials for Office 365 and its databases are mirrored and backed-up automatically by default as part of the service. The back-up data is actively stored in geographically-replicated storage which maintains copies of your data across two local Azure datacentres. When active geo-replication is enabled, we will ensure that all transactions committed to the database in your primary region are continuously replicated to the databases in the other region as well. Having cross-region redundancy enables your applications to recover in the event of a disaster (e.g. a natural disaster). This provides a robust business continuity offering, and enables you to run mission critical solutions in the cloud with confidence.
