Techniques for filesystem management for cloud object storage are described. In one embodiment, a method includes writing, by a filesystem layer, a plurality of entries to a log structured file tree, including filesystem metadata and filesystem data. The method includes performing a flush operation of the entries from the filesystem layer to one or more objects in a distributed cloud object storage layer. The method includes storing the filesystem metadata and the filesystem data to the one or more objects in the distributed cloud object storage layer. The method further includes storing flush metadata generated during each flush operation, including a flush sequence number associated with each flush operation. 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.
