File system hierarchies and functionality with cloud object storage

A system comprising:

• one or more processors communicatively coupled to memory, the one or more processors to facilitate:
• processing a first set of one or more requests to perform a first transaction with respect to a file;
• storing data blocks and corresponding metadata in one or more storage devices of a block storage system, wherein:
• the data blocks correspond to the file, and
• the data blocks and the corresponding metadata are stored separately as logical blocks according to a tree hierarchy;
• causing storage, in a cloud object store, of a set of cloud storage objects, where the set of cloud storage objects comprises data of the data blocks and the corresponding metadata of the tree hierarchy, and the causing storage comprises causing communication of a second set of one or more requests to the cloud object store to specify storage of the set of cloud storage objects in the cloud object store so that the set of cloud storage objects preserves the data of the data blocks, the corresponding metadata, and relationships of the data blocks and the corresponding metadata according to the tree hierarchy, wherein the set of cloud storage objects is stored in the cloud object store to correspond to a cloud-based instantiation of the tree hierarchy;
• processing a third set of one or more requests to perform a second transaction with respect to the file;
• converting at least one I/O request, corresponding to the third set of one or more requests, into an object interface request;
• and
• transferring the object interface request to cause communication with the cloud object store to perform at least one I/O operation with respect to at least a subset of the set of cloud storage objects.

One or more non-transitory, machine-readable media having machine-readable instructions thereon which, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• processing a first set of one or more requests to perform a first transaction with respect to a file;
• causing storing data blocks and corresponding metadata in one or more storage devices of a block storage system, wherein:
• the data blocks correspond to the file, and
• the data blocks and the corresponding metadata are stored separately as logical blocks according to a tree hierarchy;
• causing storage, in a cloud object store, of a set of cloud storage objects, where the set of cloud storage objects comprises data of the data blocks and the corresponding metadata of the tree hierarchy, and the causing storage comprises causing communication of a second set of one or more requests to the cloud object store to specify storage of the set of cloud storage objects in the cloud object store so that the set of cloud storage objects preserves the data of the data blocks, the corresponding metadata, and relationships of the data blocks and the corresponding metadata according to the tree hierarchy, wherein the set of cloud storage objects is stored in the cloud object store to correspond to a cloud-based instantiation of the tree hierarchy;
• processing a third set of one or more requests to perform a second transaction with respect to the file;
• converting at least one I/O request, corresponding to the third set of one or more requests, into an object interface request;
• and
• causing transferring the object interface request to cause communication with the cloud object store to perform at least one I/O operation with respect to at least a subset of the set of cloud storage objects.
