No. To back up to the CrashPlan Cloud service, you computer simply has to be connected to the internet somehow -- wi-fi, LAN, wherever. No VPN is required. This makes backing up much more convenient for laptops on the road.

Once your CrashPlan account is provisioned, yes. After you sign up for the service, you'll receive an email confirming your account. At that point, you'll be able to install the client software using these instructions. Of course, if you're at all unsure, especially with regard to selecting which files to back up, your Computing Consultant can assist you as well.

Yes, but be careful. In the program, on the 'Backup' tab, click 'Change' under the 'File Selection' box. You will be presented with a file selection tree with a checkbox next to each file and folder on your local machine. Placing a 'check' in the box instructs CrashPlan to back up that file or folder. A minus or a filled square appears next to a directory when only _some_ of the files or folders inside it are selected. Anything with an empty box will not be backed up. Important: When you remove files from your backup selection, all versions of the backups of those files are removed from the backup destination immediately. It's the only way for a user to cause data loss from the backup, so the software shows a warning any time you change your backup selection.related-labels
