Well, you guess it: there's no way to give you some hints based on your description. "I copy a dataset of 7GB with rsync. I don not know about the filesystems used to keep the data, I don't know the mount options used, I don't know how files change (in data as well as in metadata) and it takes about 60 min over a link with unknown speed and latency." Please give us some more hints. One hour over eg. a mobile phone connection with 9600 Baud (like 1kb/sec) for a dataset which changes completely would be quite well-working, while one hour with fast disks over a well-connected site (eg. gigabit internet upstream) with non-changing data would be catastrophic...
