Abstract: Deletion handling for incremental file migration is described. Data is received from a storage device. A modified directory is identified in the data. A list is created of files associated with the modified directory in the source device. Any files associated with the modified directory that are absent from the list of files are deleted from a storage device.

Abstract: Hard link handling for incremental file migration is described. A file is stored on a storage device. A determination is made whether a path associated with the file is also associated with an index node number in a hard link table. The file is deleted from the storage device if the path associated with the file is also associated with the index node number in the hard link table. The path is linked on the storage device with another file that is associated with another path that is associated with the index node number in the hard link table.

Abstract: Renamed directory handling for incremental file migration is described. A directory is stored in a storage device. An inode number associated with the directory in a directory table is identified. A determination is made whether the inode number equals an inode number associated with another directory in the directory table. At least one of a file and a subdirectory associated with the directory in the file system is stored into the directory in the storage device if the inode number equals the inode number associated with another directory in the directory table.
