Abstract: Methods and devices for data migration may include initially processing requests from a plurality of geographic regions for a cloud service using a global back-end service with a global storage account storing data. The methods and devices may include establishing a region back-end service with a region storage account in at least one geographic region of the plurality of geographic regions to support the cloud service for users in the at least one geographic region, wherein the region back-end service includes a region RTable. The methods and devices may include receiving, by the region back-end service, user requests for the cloud service from one or more users in the at least one geographic region and accessing, via the region RTable, one or more rows of data associated with the at least one geographic region from the global storage account in response to the user requests.

Abstract: Embodiments are directed to locating and restoring backed up items using a custom schema and to efficiently transferring recovery data. In an embodiment, a computer system defines a schema that provides data search and retrieval among backup data sets. The schema stores searchable attributes for each database item and leverages a file system to store file system metadata for the data items of the backup sets. The computer system receives a request to find data items among the backup data sets and accesses the schema to determine, from the stored searchable attributes, which recovery points among the backup data sets include the requested data items. The computer system also restores the requested data items from the determined recovery point within the backup data sets.
