Google allows you to upload documents individually or as a batch to Google Drive, formerly known as Google Docs. You can keep the original formatting or you can convert the docs so that you can edit them online.
You have options for backing up the information you store in Google.
Email: You can configure a mail client (such as Thunderbird or Apple Mail) to download your mail to your own computer, or subscribe to an online service that will perform automated backups.
Documents: You can download individual items, but when you organize your documents into "Collections" - Google's name for folders - you have the option of downloading the entire collection as a compressed (.zip) file, with the contents in a format you can work with on your own computer.
