A perl script for copying a directory tree to another location (eg a
separate hard drive for backups). It looks at the size and modification
times of the files to decide whether to copy them or not. As a result,
after the first "clone", keeping the copy up to date is a very quick
operation.
Note: If you keep a backup of your windows partition on a linux
partition, or if you use NTBackup or XCOPY to backup your windows
partition, then you also see sfn-fix
