It is a Universal unique Identifier, UUID (or GUID) is a unique identifier that can be created without a central authority. UUIDs can be used if a sequence number is not good enough. This implementation is thread safe and very fast.

If you are copying a user or group from one Liferay server to another would a uuid be certain to be unique in the new Liferay server?

Your question isn't really clear. What do you mean by "copying"? In what way is the "one Liferay server" related to the "new Liferay server"?
