Mark and Copy algorithms are very similar to the Mark and Compact as they too relocate all live objects. The important difference is that the target of relocation is a different memory region as a new home for survivors. Mark and Copy approach has some advantages as copying can occur simultaneously with marking during the same phase. The disadvantage is the need for one more memory region, which should be large enough to accommodate survived objects.
