Filesystem management for cloud object storage

One or more non-transitory computer readable storage media encoded with instructions that, when executed by a processor of an intermediate layer disposed between a filesystem layer and a distributed cloud object storage layer, cause the processor to:

• perform a flush operation of a plurality of entries in a log structured file tree of the filesystem layer from the filesystem layer to one or more objects in the distributed cloud object storage layer comprising a plurality of distributed storage devices, wherein the plurality of entries includes filesystem metadata and filesystem data;
• store the filesystem metadata and the filesystem data from the plurality of entries in the log structured file tree to the one or more objects in the distributed cloud object storage layer;
• store flush metadata generated by the intermediate layer during each flush operation, wherein the flush metadata includes a flush sequence number associated with each flush operation;
• and
• wherein each object of the one or more objects in the distributed cloud object storage layer is identified by a key that identifies the flush sequence number, an object identifier, and a rebirth identifier.

A system comprising:

• an intermediate layer disposed between a filesystem layer and a distributed cloud object storage layer;
• wherein the intermediate layer includes at least a memory and a processor in communication with the memory;
• and
• wherein the processor is configured to:
• perform a flush operation of a plurality of entries in a log structured file tree of the filesystem layer from the filesystem layer to one or more objects in the distributed cloud object storage layer comprising a plurality of distributed storage devices, wherein the plurality of entries includes filesystem metadata and filesystem data;
• store the filesystem metadata and the filesystem data from the plurality of entries in the log structured file tree to the one or more objects in the distributed cloud object storage layer;
• store flush metadata generated by the intermediate layer during each flush operation, wherein the flush metadata includes a flush sequence number associated with each flush operation;
• and
• wherein each object of the one or more objects in the distributed cloud object storage layer is identified by a key that identifies the flush sequence number, an object identifier, and a rebirth identifier.
