Latest Patents
One of Guangju Li's latest patents is a method of detecting source change for file level incremental backup. This innovative system identifies new, modified, unchanged, and deleted files in an incremental backup through a file list maintained on the backup destination. The FileList is a flat file that stores information about each file on a source node sequentially. During subsequent incremental backups, the FileList is read sequentially from the backup destination to generate a search tree. A hash value based on the file path serves as the key to the search tree, with the file's modified time and size hashed together to form the value of the tree's key-value pair. Files are examined on the source and compared to the key-value pairs in the search tree. The status information in the search tree is modified to indicate discovered files, while unmodified status information identifies files that have been deleted since the previous backup.
