I have been using it for years with great success. I've only had a couple minor problems, which were small in nature and more due to Time Machine itself rather than the fact a server is hosting the service. (Unfortunately I no longer remember the exact problems, but they were not nearly bad enough to deter me from continuing to use it. I have about half a dozen Mac devices in my home, so the net positive of continuous wireless Time Machine backups has far outweighed said small issues.)
