ABSTRACT:
A method and apparatus to recover a set of data from a full backup and an incremental or differential backup are described. This includes a source directory that was modified between the full backup and the incremental or differential backup. The full backup is restored, including the source directory, and a new directory is created to replace the restored directory when the incremental or differential backup is applied to the restored full backup. Content for an entry from the modified source directory in the incremental or differential backup is created in the new directory if the corresponding content is present in the incremental or differential backup. If the content for the entry is not present in the incremental or differential backup, then the entry in the new directory is linked to corresponding content in the restored directory from the full backup.
