If you want files and their sizes only, try:
%find . -type f -ls | awk '{print $7 "\t" $11}' | tee `hostname`
then "sort +1" them and diff or "sort -m +1 ... | uniq -u" to find
the unique entries.
If you have the time to hash all that data, try:
%find . -type f | xargs /sbin/md5 (or sha1/rmd160/sha256) | tee ...
to make sure the copied files hash identically.
"rsync -c" will use md4 hash equality instead of size and modtime
equality to pronounce files "indentical." But, if you're going to
hash the files, you might as well use sha1 or rmd160 at minimum.
