meek75, not to beat a dead horse, but if you make it a practice to image before you upgrade, you'll never need to miss a game. The only time I've been set back is when I've spent a couple hours writing and editing content and not saving and then experienced a crash. Stupid not to save, but RW is usually so stable that I've developed the bad habit of not saving frequently. As Rob stated, the recent upgrades due to the conversion to HTML have been the exception.
I do two things that allow me to never worry about missing a game and they are based upon my practices for other mission-critical applications (the ones I actually need to make a living).
(1) System Image Backup. I take an image of my computer when it is stable and every time before an upgrade that, if it causes issues, would prevent me from working/playing. I don't use imaging as a work-product backup, just a way to get back to a working system if there is an issue. The ability to quickly restore from an image has been a huge lifesaver. I've been in a hotel, the night before an important presentation at a client site, only to be stupid and allow a windows upgrade to run. And as luck would have it, this was the ONLY time a windows upgrade messed up my system...total FUBAR. I restored from an image I made before my travel, did NOT let Windows Update run, and was up and running in an hour or so. Similarly, if I have a game coming up, and an update is released, I'll take an image before upgrading, so I can quickly roll back my system if needed.
(2) Work-product backups. You could use periodic, incremental images for this. Acronis, Shadow Protect and other imaging programs advertise themselves as full backup solutions. But, in my experience, this is overkill.
First, you need the storage, which means if you don't have a large drive with lots of unused space, you need an external drive for your images. I found that when I was using image software for backing up data, I often didn't back up because I would forget or not want to pack the external USB drive or would forget to connect it and or forgot to leave my laptop on at night in the hotel or forget to put it back in the docking station at home. 2BrightSparks has a good read about the issues with using imaging as you only backup solution here:

Second, if you just want to get one file you lost, say an old pre-upgrade version of a *.realm file for RW, you need to mount the image and drill through the file directories to get it. If that image is on external media, you need that media with you. A lot of my work is now in systems that back up online, such as Google Drive, Skydrive, EverNote, and RealmWorks, or I am working in web apps or remoting into a VM. But I still have local data and I do like to have control over backing up my critical data, so I run SpiderOak to securely backup select directories containing my user-created data.
SpiderOak keeps an unlimited number of revisions for the backed up files. I never have to worry about totally losing my RW's *.realm files. There are other similar online backup software. CrashPlan is good, esp. if you have a Mac. Rackspace's JunkDisk is good. And there are others. I personally like SpiderOak's zero-trust security model, but you may be less paranoid than I.
This may all sound complicated or a hassle, but really is simple. I do this with my family. First I teach them how to make a System Image Backup with windows 7, 8, or 10 (I use ShadowProtect for performance and features, but there is no need to buy image software if you have windows 7, 8, or 10). Then I install SpiderOak. SpiderOak's online backup works in the background and you never need to worry about it until you need to recover lost data.
