I have enquired Crashplan about their plan for WP7 client and here is their reply:
"Currently, we are gauging interest for a Windows 7 mobile app. We don't support it currently, but if there is enough interest from our user base, we will certainly take it under consideration.
Our users come up with a lot of great ideas. We have setup a forum that we can use to track feature requests. We use the feedback from the Mobile Feature Requests forum to help plan our future releases. If you are interested in seeing a Windows 7 mobile app, please let us know.
