Hi Rishi,
you should also have a look at rsnapshot:

Description: local and remote filesystem snapshot utility
rsnapshot is a filesystem snapshot utility. It can take incremental
snapshots of local and remote filesystems for any number of machines.
rsnapshot makes extensive use of hard links, so disk space is only used
when absolutely necessary.

You will need to get an sshd/rsyncd for Windows though. This shouldn't
be impossible, but I am not knowledgeable in that quarter, so I can't
comment. I can say however that my home partition (40Gb, of which ~33
used) is being backed up with 7 weekly snapshots. I usually get below
40 Gb of data for all backups combined instead of ~33*7 as all unchanged
files get hardlinked instead of copied.
