Time Sync

Insync is a new syncing and backup service similar to Dropbox , but comes with a bunch of great additional features, like syncing your Google Docs and Gmail contacts.

Insync creates an always-in-sync folder on your computer that copies files to the cloud and to other machines running Insync. It also syncs your Google Docs to this folder as well, which is pretty great. If anyone shares a Google Doc with you it'll show up in your Insync folder, on your Insync page, and (of course) in Google Docs
