You need to upgrade to Beta-4. It has Rsync. The "Release" version is very old.
RELEASE is only a month or so old. Sadly, in the beta series, there are more things broken that were "added"...
I decided I'd switch back to 7.x until 8.0.1-RELEASE comes out...may even wait until 8.1-RELEASE when uPnP is done.
Some of the best things about 7.x, don't exist in any of the 8.x series - for example, the file-manager...being able to create directories and manage permissions directly is GREAT...without having to visit the console or use SSH. For semi-n00b's like me, this is pretty valuable. UPS works. Smart reporting works. Overall it's very "polished", even if it is a bit rough around the edges when it comes to ZFS by comparison and doesn't have the "pretty" front-end GUI that 8.x does.
