What I did was used cksum to create a checksum of the source file putting it in a separate file, transmitted that via rsync as well and compared that to a cksum computed on the remote end. There are far more accurate alternatives to cksum but I felt cksum was good enough for a basic check. Like most things in the UNIX world, there are probably other ways to do this as well.
Interestingly enough, after I sent my previous response I discovered that I had yet another instance of the problem.

Hi Leroy,
How I can confirm that during rsync transfer corruption are not encountered?
Thank you in advance.

> I've used rsync (but probably not for the size you're referring to), it works and has enough features to meet most needs. I have had a single situation where corruption occurred during transfer (a few times, have no idea why), might want to independently confirm the integrity of the transfer.
