Time Machine back-up and Dropbox

Being very green with Mac, I have to ask...

I've set up a Time Capsule today and everything is working just fine. But I don't know if files from my Dropbox folder is included in the Time Machine back-up. I know from PC that the Dropbox files are stored locally and only synced with Dropbox. Is this the case with Mac as well?

Since I use PC at work and now Mac at home, I find it convenient to use Dropbox. But if Time Machine doesn't back these files up then I need to find another way, because I don't want to trust Dropbox as my only back-up.

Not what I'm experiencing. Yes, Time Machine did initially backup the dropbox folder, but I am not seeing new changes or new files appearing in the regular backup. It just appears to be a static version of when I started time machine. Be sure to check that your file changes are being stored.


I don't have that problem...

This morning, at work and from my employer's PC, I added several new files to my Dropbox to work further with at home. When I started my Mac, Dropbox started sync.

Just now I checked my Time Machine and all the files new to Dropbox today were there - both one and two hours past.


These files came to my Mac from Dropbox sync and wasn't created on my Mac, so I checked a couple of other things in my Dropbox folder as well.

Half an hour later I started another back-up, and found again that I can rewind to how Dropbox folder looked like before all my testing.

And Dropbox in the cloud has of course also synced and looks just like my Dropbox folder...


One thing I haven't tested - what happens to Dropbox in the cloud if I rewind my Dropbox folder with TM and then sync Dropbox...? I do not want to risk that before I have researched a bit first.

I suppose I can temporary quit Dropbox app, rewind with TM, then relaunch Dropbox app. I think Dropbox then would assume the changes appeared offline and then change to how Dropbox folder on my Mac looks like. But of course it COULD just happen that Dropbox will change my Dropbox folder to how it was before I rewinded with TM...

I'll post back if I find out anything
