Still having issues on the 10.10.2 beta.
My Ethernet-connected (2012) Mac Mini almost-always backs up fine, although I've had to reboot the Time Capsule (late 2013) once so I could retrieve an old file from Time Machine. It wouldn't connect to the TC.
My late 2013 rMBP has issues all the time. Last TM backup completed, and I almost immediately went into Time Machine to get a file I accidentally deleted, and it gave me an error saying it couldn't find the backup disk. Happens all the time. Not to mention it connects at less-than-AC speeds more often than I'd like (yes, it's only a few feet away in the same room).
I haven't owned a Time Capsule prior to Yosemite coming out, but back when I had an external, I never had any issues. I agree that it's a Yosemite issue, though it may take a TC update to fix it. Unfortunately, 10.10.2 doesn't seem to be the savior I was hoping it'd be.
Oddly enough, having Airport Utility open usually helps with connectivity issues (as mentioned).
