  4. Let Arq create a new bucket or pick from one you've already created before 

  5. Arq is now configured to use ObjSpace. On the main screen you'll see ObjSpace on the left sidebar. Select the 'Add A Folder...' option

Arq is now ready to use with ObjSpace and will (by default) backup your selected folders every hour.
