If you have configured your Spanning Backup Universal Restore button, but the Salesforce 'Chat' icon overlays it, then you need to disable the 'Allow a chat widget to be included in custom Visualforce pages.' setting in your Salesforce account.
To disable this setting, follow these steps:
1. Log into your Salesforce account as the admin user.
2. Click the 'Setup' button in the upper-right corner of the screen
3. In the left-side navigation panel, navigate to Build > Customize > Chatter > Chat Settings
4. Click Edit.
5. Un-check the box for 'Allow a chat widget to be included in the custom Visualforce pages.'
