Abstract
A system and method for generating and updating a file system on a client computer. An original file system may be compared to an updated file system and the differences between the two file systems may be defined in specific data blocks. The differences may include new data blocks, modified data blocks, and data blocks that have been deleted. The new data blocks or modified data blocks may be sent to the client computer along with reference file updates to update the file system on the client computer. A virtual file system on the client computer may be created using the set of data blocks and the reference files to point to which data blocks contain the data for specific files. As the file system is updated, new data blocks and modified data blocks may replace deleted data blocks in the set of data blocks.
