Perhaps we should create a topic called “Known pitfalls and confusions”? Things to include there would obviously be the filtering logic in general and this symbolic links issue in particular. Another thing might be the terminology issue around snapshots etc.

Another thing I can think of would be fixed vs variable chunksize (pointing out that it might be worth working with two repositories, one for databases etc and the other for the rest.

-bit-identical might be another candidate, though it’s probably not relevant for the average user.
