System and method of using data blocks to optimize file storage

A system for managing electronic data stored in a storage service, the system comprising:

• a processor configured to:
• store, in the storage service, a plurality of data objects that correspond to a main block and a plurality of secondary blocks of a data file, wherein the main block is stored in a first bucket and has a name being a file name of the data file, wherein the plurality of secondary blocks are stored in a second bucket and have names containing coded offsets relative to a start of the data file, wherein the main block includes metadata indicating a unique identifier of the second bucket and each secondary block contains a portion of the electronic data;
• after the data file is stored in the storage service, perform a sparse operation of the data file to determine at least one region of the data file that contains unused space, and
• responsive to determining that the at least one region that contains unused space completely overlaps at least one secondary block of the plurality of secondary blocks, remove the at least one secondary block from the data file;
• and
• update the metadata in the main block to remove a respective name of the at least one secondary block to indicate that the at least one secondary block was removed from the data file to make the data file accessible by a user.

A non-transitory computer readable medium storing computer executable instructions for managing electronic data stored in a storage service, including instructions for:

• storing, in the storage service, a plurality of data objects that correspond to a main block and a plurality of secondary blocks of a data file, wherein the main block is stored in a first bucket and has a name being a file name of the data file, wherein the plurality of secondary blocks are stored in a second bucket and have names containing coded offsets relative to a start of the data file, wherein the main block includes metadata indicating a unique identifier of the second bucket and each secondary block contains a portion of the electronic data;
• after the data file is stored in the storage service, performing a sparse operation of the data file to determine at least one region of the data file that contains unused space;
• and
• responsive to determining that the at least one region that contains unused space completely overlaps at least one secondary block of the plurality of secondary blocks, removing the at least one secondary block from the data file;
• and
• updating the metadata in the main block to remove a respective name of the at least one secondary block to indicate that the at least one secondary block was removed from the data file to make the data file accessible by a user.
