Back Up Options

I recently took part in discussion on ways to back up data to an external
drive.

This works fine, but it simply updates any new or changed files. This means
that if a file is moved from one folder to another or its name is changed,
then the backup may contain duplicates.

Is there a command or a readily available (i.e. free) program which will
compare two sets of files with each other and report the differences.
e.g. when comparing folder x on drive C: and Drive F:
Files on C: and not on F:
a
b
c
d
e

Files on F: and not on C:
s
t
u
v

This won't resolve files which have changed name, but will help a bit.
 
I posted this a while ago but got no replies, so I am posting again with a
different heading.

Can anyone help?

IF all you want is to be sure the files are identical and you
don't have to -see- those differences, running a crc on them is
quite useful. Or better yet, a hash calculation. Lots of places
to get such utils free on the 'net.
