Do you store important data files outside your user profile? Custom libraries can help you ensure that those files are always backed up. Create a new library, call it Backup, and make sure it’s selected in your current backup settings. Add locations to the new library that you want to ensure are backed up. The files themselves remain in their original location, but as long as they’re on a local drive they’ll be backed up. If you remove a folder from the Backup library, it will no longer be backed up. Any new folder you add here, even if it’s outside your user profile, will automatically be included in your next backup.
