		<description>Thanks for the extra info.  As my main concern is backup, I&#039;ll probably resort to periodic ZIP archiving and put this in Dropbox or Google Docs.

Alternatively, I&#039;m using Git locally (I&#039;m new to Git) with Egit in Eclipse, so I might try pushing my code to GitHub as a backup.</description>

		<description>In your home directory there is a .dropbox directory.  It seems to have a copy of every variation of your files, at least for some period of time.  This folder can grow to a fairly substantial size if you make a lot of frequent changes.  It&#039;s something you don&#039;t notice on newer systems but I also have Dropbox installed on my netbook with a whole 16 GB disk (including Windows XP installation) and an older Linux system with a smaller disk and a nearly full /home partition and they were so overwhelmed that I had to uninstall Dropbox, delete the directory, and reinstall.

The other issue is the network traffic involved.  The dropbox daemon sends a copy of every changed file to the server (where you&#039;re working) and pulls it down from the server (on all other systems where you have dropbox running) so your network usage can really add up.  That&#039;s a good use of network resources if you&#039;re creating new content, e.g., editing source files, but your class files can be regenerated at any time from your source files - there&#039;s no real gain in distributing them to other dropbox instances.  That&#039;s the other concern I had when putting all of my class files in a different directory.</description>

		<description>Hi. I&#039;m a Dropbox user, on a free account with about 8GB, 60% used. I&#039;m considering syncing some of my Eclipse projects to Dropbox, mainly as a backup, but also possibly for work on other PCs. I use Ubuntu 10.10 on my main PC and Windows7 on the other.

I was planning to put the Eclipse project folder in Dropbox, as per your Second Attempt.  It would seem a good approach.  My Ubuntu set up is a single main partition, including /home, with plenty of space.

In your description of the problem with your Second Attempt, you mention the changes log maintained by Dropbox. Is this on their website?

I do wonder whether it&#039;s wise to use something like Dropbox to sync a dev environment that is frequently generating new versions of build files. There would be a lot of updates.  My alternative plan is to periodically (maybe manually) create a ZIP archive of my Eclipse project and copy this to Dropbox, keeping the actual project folder outside of Dropbox.

I&#039;d be interested in your thoughts on this and to hear how you are getting on with your own Dropbox Eclipse set up.
