Sprint Backlog : Sprint Backlog is a list of features and needs that are linked with a particular sprint. In other words, it entails all that must be completed during a certain sprint. It's a subset of the product backlog, and the development team is in charge of keeping it up to date.
Product Backlog : Product Backlog, contrary to the sprint backlog, includes all of the features and requirements for the complete product. It entails everything that must be accomplished during the product development process. It also splits items into different jobs. It's a superset of the sprint backlog, and it's owned by the project manager.
