One of the apps I’ve really come to love is Things. All it is is a ToDo List generator but it’s conquers the task with so much ease that I just can’t fault it.
However with my growing dependency on it grows my need to keep those tidbit’s safe, and like the Ad says “theres an app for that” 
I have to admit something now, I never heard of DropBox till Paul Boag announced them as winners in this year’s .NET awards; must be losing my touch because this gem really is wonderful.
DropBox is simply a directory on your machine (be it Mac, Win or Linux) that sits there and mirrors whatever you put into it in a virtual memory stick on the web, backing up your important bits seamlessly in the background while you continue to work. No annoying “44% done” popup’s or “Connection Failure!” prompts, if it gets into a tiz it simply fixes itself and leaves you be until you fill up your free 2GB allowance.
Then if you fill up that 2GB you can pay to increase it to 50GB or 100GB, renewable monthly ($9.99) or yearly ($99)
Anyway I digress, back to the matter of hand.
With DropBox installed, make sure Things isn’t running then fire up Terminal and type:
mkdir -p ~/Dropbox/Library cd ~/Library/Application\ Support/Cultured\ Code mv Things ~/Dropbox/Library/Things rm -rf Things ln -s ~/Dropbox/Library/Things Things
What we’ve basically done here is move Things’s ToDo database into the DropBox folder, then created a symbolic link from it into the orginal database’s location. Fire up Things and it’s none the wiser, but take a gander at the DropBox icon in your menubar and you’ll notice it quietly backing up that database, just in case the worst happens.
Priceless!
