Upgrade method, computer system, and remote upgrade device implementing efficient remote upgrade

A remote upgrade device for remotely upgrading data stored in a computer system comprising a storage device, comprising:

• a first storage device, comprising a program code and a new file;
• a memory device, connected to the first storage device for loading the program code;
• and
• an interface, adaptable for remotely connecting the computer system;
• a processor, connected with the memory device;
• the processor executes the program code to implement an upgrade method for upgrading an original file stored in the storage device into the new file;
• wherein:
• the storage device comprises a plurality of storage blocks each having a predetermined block size and associated to one of a plurality of block numbers, the new file comprising a plurality of file blocks each associated to one of the plurality of block numbers;
• and
• the upgrade method comprises:
• transmitting an upgrade notification comprising a list of block numbers of the plurality of file blocks;
• receiving check codes of data stored in the storage blocks, wherein each of the received check codes corresponds to one of the block numbers in the list;
• respectively comparing the received check codes with check codes of the plurality of file blocks;
• when the comparison finds that a check code of a file block is matched to a received check code of a same block number, not transmitting the file block;
• and
• when the comparison finds that the check code of the file block is inconsistent to the received check code of the same block number, transmitting the file block to upgrade a storage block corresponding to the same block number.

An upgrade method for upgrading an original file stored in a predetermined area of a storage device into a new file, wherein the predetermined area comprises a plurality of storage blocks each having a predetermined block size and associated to one of a plurality of block numbers, the new file comprises a plurality of file blocks each associated to one of the plurality of block numbers;

• the upgrade method comprises:
• receiving an upgrade notification comprising a list of the block numbers corresponding to the plurality of file blocks;
• transmitting check codes of data stored in the storage blocks:
• wherein each of the transmitted check codes corresponds to one of the block numbers in the list, wherein the transmitted check codes are respectively compared with check codes of the plurality of file blocks, and when the comparison finds that a check code of a file block is matched to a transmitted check code of a same block number, the file block is not transmitted to the storage device;
• and
• when the file block is received by the storage device, writing the file block into a corresponding storage block in the storage device.

A computer system comprising:

• an interface, configured to connect with a remote upgrade device;
• a storage device, connected with the interface, comprising a program code and a predetermined area, wherein the predetermined area comprises an original file;
• a memory device, connected with the storage device and the interface for loading the program code;
• and
• a processor, connected to the memory device, the storage device and the interface, executing the program code to implement an upgrade method for upgrading the original file stored in the storage device into a new file, wherein:
• the predetermined area comprises a plurality of storage blocks each having a predetermined block size and associated to one of a plurality of block numbers, the new file comprises a plurality of file blocks each associated to one of the plurality of block numbers;
• and
• the upgrade method comprises:
• receiving an upgrade notification comprising a list of block numbers corresponding to the plurality of file blocks;
• transmitting check codes of data stored in the storage blocks:
• wherein each of the transmitted check codes corresponds to one of the block numbers in the list,
• wherein the transmitted check codes are respectively compared with check codes of the plurality of file blocks, and when the comparison finds that a check code of a file block is matched to a transmitted check code of a same block number, the file block is not transmitted to the storage device;
• and
• when the file block is received by the storage device, writing the file block into a corresponding storage block in the storage device.
