A method, system and non-transitory computer readable instructions for application patching comprising, concatenating compressed data or uncompressed data or a mixture of compressed and uncompressed data into a continuous data set into a continuous data set and dividing the continuous data set into variable sized data chunks. Compressing each of the variable sized data chunks and dividing each of the variable sized data chunks into fixed size data blocks. Encrypting the fixed size data blocks to generate encrypted fixed size data blocks and storing the encrypted fixed sized data blocks or sending the encrypted fixed size data blocks over a network.

Application patching using variable-sized units

A method, system and non-transitory computer readable instructions for application patching comprising, concatenating uncompressed data into a continuous data set and dividing the continuous data set into variable sized data chunks. Compressing each of the variable sized data chunks and dividing each of the variable sized data chunks into fixed size data blocks. Encrypting the fixed size data blocks to generate encrypted fixed size data blocks and sending the encrypted fixed size data blocks over a network.

A method, system and non-transitory computer readable instructions for update optimization comprising, receiving application metadata wherein the application metadata includes a likelihood of future data change metric for one or more regions of application data. Determining from the application metadata which regions of the application data have a high likelihood of data change and generating variable data chunk boundaries based on the regions of the application data that have the high likelihood of data change.
