For example, I'm moving my Steam over to another internal drive. This way when I backup my Windows C drive the backup won't be so big (and long). But even though I can always re-download the steam files it would be nice to occasionally backup the Steam directory or the drive that has this directory on it so if I do lose these files I don't have to re-load all of them. I could occasionally do one big backup but then when I restored it I would be losing all the other backups that occurred since then so that doesn't appeal. So lets say my C drive dies and I get a replacement (Paragon image backup program allows me to restore to different hardware). I restore my C drive (windows xp) backup that was last updated 1 hour before the c drive died and then restore my D drive backup which contains the Steam folder. But the D drive backup is one month old. Will everything work ok (apart from the obvious fact that Steam will be less up to date than the rest of the system)?
