Just an FYI... SuperDuper! v2.7.3 is the version that's for Yosemite. I've been using this version since upgrading to Yosemite, and I've not experienced any cloning issues.
After using SuperDuper for many years, I reverted back to Carbon Copy Cloner, because CCC will also handle the Recovery Drive. Has that been added to SuperDuper yet? I scanned ShirtPocket's web site and there was no mention of the Recovery Drive.
