I\'m getting a confusing error from rsync and the initial things I\'m finding from web searches (as well as all the usual chmod\'ing) are not solving it:
rsync:
The problem in my case was that the "receiver mountpoint" was incorrectly mounted. It was in read-only mode (for some extrange reason). It looked like rsync was copying the files, but it was not. I checked my fstab file and changed mount options to default, re-mount file system and execute rsync again. All fine then.
