Using one drive to backup Mac and PC
A few people have asked how I use one drive to backup both my Mac (using Time Machine) and my PC (using Windows Backup), so I thought I'd document it in case it's useful to anyone. There might be other guides on how to do this, but here's how I did it - it's fairly easy if you're familiar with partitioning, formatting and generally messing around with drive management. If you're like me and have both a PC and Mac, backing them both up to the same drive can be very convenient (though make sure you do backup elsewhere too, one drive for everything means if that drive dies, you've lost two computers' backups!). There are other backup options than the aforementioned defaults included with the OS, but I find they work well enough for me so I'm happy to use them :) Please also note that this is how I did this, and it is not the only way (or perhaps even the best way - I don't claim to be an expert at these things).
