Extents record ++whether or not specific parts of the disk are allocated or sparse. ++ ++You can use this with plugins which cannot get extent information ++themselves, but you can get this information from another source. One ++place where it is useful is with L because the ++sftp protocol does not support reading sparseness information, but you ++may be able to get this information directly from the source disk on ++the remote server. ++ ++=head1 FILE FORMAT ++ ++The list of extents is specified in a text file. There is one extent ++specified per line. Each line has the format: ++ ++ offset length type ++ ++The C and C fields may use any format understood by ++C. The optional C field may be an integer, ++missing (same as 0), or a comma-separated list of the words C ++and C.
