System and method for replicating file systems in remote object storages

A non-transitory computer readable medium having stored thereon instructions for causing a processing circuitry to execute a process, the process comprising:

• copying at least a portion of a file system from a first storage, wherein the at least a portion of the file system includes underlying data and metadata, wherein the metadata includes pointers to portions of the underlying data and metadata defining a file system hierarchy of the file system;
• partitioning the copied data of the file system into a plurality of blobs, wherein the plurality of blobs includes a plurality of data blobs and a plurality of metadata blobs, wherein each data blob includes at least one portion of the underlying data, wherein the plurality of metadata blobs include a plurality of data content blobs and a plurality of name content blobs, the data content blobs having pointers to respective data blobs of the plurality of data blobs, wherein the name content blobs are created based on the metadata defining the file system hierarchy of the file system;
• generating a plurality of filter objects based on the copied data, wherein each filter object includes a list of metadata blobs, wherein the metadata blobs listed in each filter object include at least one of the plurality of data content blobs and at least one of the name content blobs;
• and storing the plurality of blobs and the plurality of filter objects in a second storage.

A system for replicating a file system, comprising:

• a processing circuitry;
• and
• a memory, the memory containing instructions that, when executed by the processing circuitry, configure the system to:
• copy at least a portion of the file system from a first storage, wherein the at least a portion of the file system includes underlying data and metadata, wherein the metadata includes pointers to portions of the underlying data and metadata defining a file system hierarchy of the file system;
• partition the copied data of the file system into a plurality of blobs, wherein the plurality of blobs includes a plurality of data blobs and a plurality of metadata blobs, wherein each data blob includes at least one portion of the underlying data, wherein the plurality of metadata blobs include a plurality of data content blobs and a plurality of name content blobs, the data content blobs having pointers to respective data blobs of the plurality of data blobs, wherein the name content blobs are created based on the metadata defining the file system hierarchy of the file system;
• generate a plurality of filter objects based on the copied data, wherein each filter object includes a list of metadata blobs, wherein the metadata blobs listed in each filter object include at least one of the plurality of data content blobs and at least one of the name content blobs;
• and
• store the plurality of blobs and the plurality of filter objects in a second storage.
