I've never known anyone to have so many problems/issues with Time Machine backups / Time Capsule as you're experienced. I have used Time Machine first on a 2TB Time Capsule before changing to a 3TB Time Capsule with my current backups history going back to January 2012. I've never had any problems with my 'Simultaneous Dual-Band 802.11n Wi-Fi Network' or 'Time Machine backups' to either Time Capsule. I did a final SD Bootable Backup & a TM Backup prior to installing Yosemite (as I always do before any upgrade of the OS). I kept TWO copies of the 5.17GB "Install OS X Yosemite.app" - one on my Desktop that I used to install Yosemite and another copy in my "Installers Folder". After installation completed I went through the normal steps of signing in to Apple ID/iCloud/Messages etc - updating databases (by opening all Apple Apps), upgrading applications, repairing permissions, and testing that everything worked correctly for a couple of days before turning on Time Machine to backup. Time Machine 'Preparing Backup' took a bit longer than normal (as expected) as it read the new operating system, plus TM had not backed up for two days. The backup went ahead and completed without any problem. The backup was 31.90GB (which is what I expected). I tested the backup to see the changes I had made working for two days and all was correct. So I don't have any idea 'why' or 'how' your previous ~630GB Mavericks Time Machine backup 'Sparsebundle' was deleted... A Sparsebundle does not delete itself!! And what the heck is the 4.5GB Sparsebundle? .... did you have anything connected to your Mac? Your son's 13GB sounds fair - the Yosemite operating system is 8-10GB, I noticed my HD 'Used': space had increased quite significantly after the installation.
