Abstract: A system, method, and computer program product for a block-based backing up a storage device to an object storage service is provided. This includes the generation of a data object that encapsulates a data of a data extent. The data extent covers a block address range of the storage device. The data object is named with a base name that represents a logical block address (LBA) of the data extent. The base name is appended with an identifier that deterministically identifies a recovery point that the data object is associated with. The base name combined with the identifier represents a data object name for the data object. The named data object is then transmitted to the object storage service for backup of the data extent. At an initial backup, the full storage device is copied. In incremental backups afterwards, only those data extents that changed are backed up.

Abstract: A system and method for recovering data backed up to an object store are provided. In some embodiments, the method includes identifying an address space of a data set to be recovered. A set of data objects stored by an object-based system is identified that corresponds to the address space and a selected recovery point. The identified set of data objects is retrieved, and data contained in the retrieved set of data objects is stored to at least one storage device at a block address determined by the retrieved set of data objects to recreate the address space. In some embodiments, the set of data objects is retrieved by providing an HTTP request and receiving the set of data objects as an HTTP response. In some embodiments, the set of data objects are retrieved based on the data objects being the target of a data transaction.
