(yes, decided to try to post some more, got really busy for a while and this project - among many others - got sidelined...)
A couple days ago Dropbox saved me from a significant amount of repair work. Dropbox is a free online backup/file sync tool available for windows, mac and Linux. Basically you set up a folder different computers. Anything in that folder is a synced to all the other computers. This is handy for easily keeping things available that you need on different machines.
It's also handy for collaborating with other people, in that you can give people access to specific subdirectories of your dropbox folder. I did this for a project I was working with a designer on. He spent hours working on a photoshop file, then told me that it was ready for me to use...
I opened the file, and only about 10% of the required stuff seemed to be there! Uhoh. I called him, and he swore up and down that he'd done the work, etc.
Well, Dropbox also has another handy feature - previous versions of files are available via its web interface. So I logged into the web interface, found the file in question and found that sure enough its file size had been quite a bit larger a couple versions back. I restored the file and *presto* all the necessary stuff is there! Whew! Somehow he'd overwritten the file with an older version.
So, if you haven't already check out dropbox. I've really had zero problems with it, and it's really quite handy - and occasionally a real life saver!
