clone is a file tree cloning tool which runs 3 threads - a scheduler (main), a
|
|
reader, and a writer thread. Reading and writing occurs in parallel. While this
|
|
is most beneficial for copying data from one physical disk to another, clone is
|
|
also very well suited for cloning a file tree to any place on the same disk.
|
|
|
|
Cloning includes the whole directory hierarchy, i.e. sub-directories, files,
|
|
hard links, symbolic links, attributes (modes, flags, times), extended
|
|
attributes and access control lists.
|
|
|
|
clone is useful for cloning (thus backing-up) live file systems, and it can
|
|
also be used in incremental and synchronization mode.
|
|
|
|
clone works on FreeBSD and Mac OS X.
|
|
|
|
clone is very fast, for example, cloning a whole UFS2 file hierarchy on
|
|
FreeBSD 9.1 of in total 2.3 TBytes of data from one hard disk to another
|
|
took 7.5 h, so the average transfer rate for all kind of files (very small
|
|
up to very big ones) was about 89 MByte/s.
