Our Rsync setup was upgraded to 4.0.4 on client and server to resolve a performance issue and performance is much better.
I noticed on the old version (4.0.3 on the server and 2.1.4 Update 400 on client) RSync was copying while files instead of just the changed blocks. Files that had been there for a year were getting recopied and this was a huge problem.
1. Anyone know why it was copying a file that was there for over a year?
2. Anyone know why it was copying the whole file in those cases? I am using the --no-whole-file option in the command as well with no luck.
