Are there different types of product backlogs? What are they & how are they different from one another?

Your general answer is no there is only one product backlog.

Your more complicated answer is, do you want there to be more than one? Reality does not always adhere to an Agile method like Scrum

In more scaled up Agile versions companies may choose to have individual teams specialize in different areas. This could create a product backlog for back-end server development and a product backlog for front-end UX development as examples.

Generally, for a single project, you really only want one core product backlog for all teams involved in the project to draw from. This prevents having to maintain multiple backlogs and accidentally having two teams work on the same stuff.

The product backlog is different than the Sprint (or iteration) backlog. The product backlog should contain "all" currently known items to be worked on. The iteration backlog would be just those items that need to be worked on during the given iteration.

Yeah there is, there;s the product backlog you have for this company, and the product backlog you have for that company. They differ in the way they are populated with stories/items, the way they are prioritized, if they are also risk prioritized, their level of granularity, their size, who has access to edit (PO and Dev Team?), and the list goes on.

Are these not considered as different types of product backlogs?
01. Release backlog
02. Prioritized product backlog
03. Risk-Adjusted backlog

Release backlog wouldn't be the product backlog.

The prioritized product backlog is what you would do to the product backlog - prioritize it (by value usually). Once you prioritize it, the higher up elements would be first in line to be chosen for the next iteration.
You can also adjust the backlog by risk. But it is still the product backlog, it is just adjusted to try and complete the riskiest items first.(ie prioritized or adjusted for risk reduction).

Nope, they are different. And the risk-adjusted or prioritized backlog is the same backlog. There is only ONE product backlog in an Agile project :-)

Actually, there is only 1 product backlog that Agile theory says.
However, few organizations end up in classifying the product backlog like feature backlog, quick enhancements backlog, technical debt backlog, etc. This classification is usually depending upon the release plan every organization has for the project.

Just to clarify, the release backlog is a different name (not a different backlog) to the product backlog. It is in fact a subset of the product backlog, like the Sprint Backlog. The best way to not get confused is just to say there is one product backlog, and we use various other names to represent different versions/subsets of the same backlog.

In my experience, there's only one product backlog.
