I've been running the various DPs for a while now on a separate partition, and last week decided to take the plunge and use a clean installation DP4 as my main OS. After installing, I've tried going into my old Time Machine backups to recover some files from the old installations, but I can't seem to get anywhere. I've not set up TM on my current installation, so have just selected "Browse Other Backup Disks" but when TM appears, all I can see is my current files. I can't see anything from the old installations, or any history older than today. What am I doing wrong here, or is something wrong with TM/Yosemite?
