the biggest flaw with windows home server is a 260 character limit on files that are to be duplicated using the storage balancing system.
a common thing that people want to do is mirror their user folder.
as it happens, i have deep paths on my computer that when copied under a logical hierarchy on the homeserver (such as \\homeserver\users\username\backup\computername\) are longer than the 260 character limit and fail to replicate.
