Efficient file recovery from tiered cloud snapshots

An apparatus, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the apparatus to:
• mount a file system in a user space partition of virtual memory of a computing device;
• expose, via the file system, one or more virtual files of a virtual machine, wherein the one or more virtual files correspond to one or more loop devices configured to map files of the virtual machine to the one or more virtual files;
• receive a request to read a data block stored at the virtual machine;
• identify, using information included in a set of metadata at the one or more loop devices, a file and a corresponding virtual file of the one or more virtual files that stores the data block, wherein the file and the corresponding virtual file comprise at least a subset of virtual files stored on the virtual machine;
• read the data block from a location indicated by the set of metadata and corresponding to the file and corresponding virtual file;
• and
• download the file and the corresponding virtual file of the one or more virtual files that stores the data block.

A non-transitory computer-readable medium storing code, the code comprising instructions executable by one or more processors to:

• mount a file system in a user space partition of virtual memory of a computing device;
• expose, via the file system, one or more virtual files of a virtual machine, wherein the one or more virtual files correspond to one or more loop devices configured to map files of the virtual machine to the one or more virtual files;
• receive a request to read a data block stored at the virtual machine;
• identify, using information included in a set of metadata at the one or more loop devices, a file and a corresponding virtual file of the one or more virtual files that stores the data block, wherein the file and the corresponding virtual file comprise at least a subset of virtual files stored on the virtual machine;
• read the data block from a location indicated by the set of metadata and corresponding to the file and corresponding virtual file;
• and
• download the file and the corresponding virtual file of the one or more virtual files that stores the data block.
