ABSTRACT:
A system and method for object-level snapshot creation in an object-based storage system. The host device includes a first object management table (OMT) and a file system. The object-based storage system is connected to the host device and includes a controller and object-based storage devices (OSD). The controller includes a snapshot module, a second OMT. The snapshot module receives and processes OSD and other commands from the file system or a service processor, creates an original object and a mirror object in an OSD, and initiates a snapshot operation in an OSD. The first OMT may also reside at a metadata server. A snapshot operation may be a mirror operation or a copy on write operation. The first OMT and the second OMT maintain mapping information of a file identifier, a partition ID, and an object ID, and an object status and a generation number of snapshots.
