You can check hash e.g. sha1sum. I would tar the whole directory and calculate sha1sum on the fly:

Code:
tar czf - /path/to/dir | sha1sum

Then do the same on the other side and verify that the checksums are the same.

On a second thought, this may give different checksums if there are different version of tar or gzip on the different machines...

Perhaps better to store checksums in a file and check them from there.

Code:
find /path/to/dir -type f -exec sha1sum {} \;  > sums.tmp

Copy the file over to the other machine:
Code:
scp sums.tmp <user>@<remoteServer>:~

And verify against this file on the remote machine:
Code:
sha1sum -c ~/sums.tmp
