Abstract
A technique for accelerating the creation of a hyperclone of a virtual file system. Specifically, each data block and indirect block directly referenced by a base inode are only copied. The hyperclone may then reference the original data blocks and original indirect blocks. Further, an indication may be provided for at least one of the copied data blocks and indirect blocks that indicates that the at least one of the copied data blocks and indirect blocks is in use.
