Windows News Group Users,

I am looking for a backup solution that will copy files from an internal
disk to an external disk, but instead of copying over all of the files
every night, make a hard link copy of the files, then sync the source
disk to the latest hard link copy. The result is 7 copies of of the
data on the external disk that are using hard links to point to the same
physical data on the disk, but where a file changes the sync util
deletes the hard link before copying the new file which means you end up
with a 7 day rotation that only consumes the space of the data plus change.

This is hard to explain so look at:
http://www.mikerubel.org/computers/rsync_snapshots/ for more information.

I do this on my linux machines and it works really well, so I would like
the same thing for windows, but just can't find any programs free or
otherwise that do the same thing. I did notice that windows supports
hard links when I did some testing in cygwin, but I would rather
download or buy a program that does this instead of installing cygwin on
the machines that need this type of backup.

Hopefully one of you has heard or seen this kind of backup for windows,
if so, please let me know.

Thanks,
schu
