Hi there,
my two cents worth of insight are the following, although I should preempt, that afaik this only works in a “pure” Windows environment. No chance for me to test it in Mac or Linux as I don’t use either. In theory similar solutions should work there too.
I am in a similar position as you, I have a work-horse PC at home and I am using my laptop when I am travelling (and I do that a lot). As I do not trust the cloud (yep, I do have a backup system installed at my home-office), synching files through the web is not an option for me. So here is what I do:
I have created a primary partition on my trusted Lenovo X200 Laptop’s harddrive of 25GB with a specific drive letter assigned to it. This is where I keep all my live data, Scrivener projects, Dragon user profiles, Word documents, User templates, spreadsheets and the like. 25GB is plenty for that.
When I am at home and I want to use the workhorse PC (i7, 16 Megs Ram… pretty fast) I have created a network-map to my laptop (which sits in a networked docking station the minute my feet hit the doormap), mapping the networked drive to that same drive letter as is assingned on my laptop. Logic and my lifestyle dictates, that wherever I am that’s where my laptop goes, the most current data must be on the laptop hard-drive. So when I use Scrivener on my PC, all I need to do is open the files in that mapped network drive. Problem solved.
Through an automated backup that actually detects if my laptop is in my home-office network environment, all my data from that drive is backed-up automatically to a NAS-device on my local network and from there to a cloud based vault (which uses password encrypted files for privacy) as well as once a month automatically to an external drive… (That’s what the cloud is really useful for!)
My data is safe, I always have the latest version of my live files with me and I don’t need to trust ye ole cloud for messing with my live files and data when synching between machines (and trust me, that can be a major nightmare!).
As the Scrivener licence allows for a dual install as long as you stay in the same OS-environment that works wonders form me. The minute I unplug my laptop and go offline (I do that a lot when I am actually writing in order not to be disturbed by email or just the urge to surf for a couple of minutes) I always have the current version of my files with me, no hassle with syncing files, up- or download files through a cloud service… And as the Scrivener files a very small files (numerous but small), you don’t even notice the slight network lag on a 1Gigabit-LAN when it autosaves. It sure beats those darn cloud services speed-wise.
