Incremental backup to object store

A non-transitory machine readable medium comprising instructions for performing a method, which when executed by a machine, causes the machine to:

• perform a plurality of backups from a node hosting a volume to an object store;
• utilize a storage application programming interface (API) to obtain file metadata changes after each backup of the plurality of backups to the object store;
• build a catalog containing file paths and inode numbers of files based upon the file metadata changes;
• in response to receiving a request to restore a file of the volume from the plurality of backups of the object store, utilize the catalog to identify a file path and an inode number of the file;
• and
• implement a single file restore operation to restore the file from backup data within the object store to the volume, wherein the single file restore operation uses the file path and inode number from the catalog to access the backup data.

A computing device comprising:

• a memory comprising machine executable code for performing a method;
• and
• a processor coupled to the memory, the processor configured to execute the machine executable code to cause the processor to:
• perform a plurality of backups from a node hosting a volume to an object store;
• utilize a storage application programming interface (API) to obtain file metadata changes after each backup of the plurality of backups to the object store;
• build a catalog containing file paths and inode numbers of files based upon the file metadata changes;
• in response to receiving a request to restore a file of the volume from the plurality of backups of the object store, utilize the catalog to identify a file path and an inode number of the file;
• and
• implement a single file restore operation to restore the file from backup data within the object store to the volume, wherein the single file restore operation uses the file path and inode number from the catalog to access the backup data.
