Alternatively, you can use "diff from_dir to_dir" to

Rsync does it's own file-by-file verification.

thanks for the reply....
my problem is not with by-file verification,
but on the directory as a whole....
Not sure I follow you. Both methods /do/ check "the directory as a
whole" -- i.e. the entire contents of the directory and everything under
it, however they do it at a level of comparing individual files.
"diff d1 d2" (Oops, I see now that I forgot the "-r" option: "diff -r d1
d2") will compare each file, and the directory structure as well, but
does not check file metadata (permissions, times, owner, etc.).
Rsync's /raison d'etre/ is to make exact copies of entire directory
trees, including metadata, so if it finishes without error, you can be
confident that you have a good copy.
Giving tar the "--verify" option will cause it to do checksum
verifications as well.
If you require a method that works 'offline'--without access to the
actual directories themselves--then that's a different issue.
