I am transferring files from a Linux computer to a Mac. The connection sometimes drops and I restart. This is usually fine, but I check everything for a possible data corruption using md5sum.
With rsync -avc it took time to generate the checksums, but then it reported everything in order.
I have double checked this with md5sum and found they are different. Substantially different. It seems that either rsync checksum is too simple (crc?) or just not working.
Linux rsync is 3.1.1 and on OS X I have tried the native 2.6.9 and homebrew-installed 3.1.2.
Any ideas?
edit:
linux:md5sum filenameos x:md5 filenameand then see that the hashes are different which i verified by checking the contents of the files.

--checksum on its own is not enough, and only worked when using rsyncd.
I figured out how to do delta transfers with rsync over ssh using these three parameters. works great now, fixing corrupt transfers.
rsync -av --checksum --inplace --no-whole-file user@server:/source/ /destination/
