What are Valid Data Blocks?

Valid data blocks are blocks that are allocated or used by a file system, for example, Ext. SMS migrates only valid data blocks. For data blocks that are not allocated or used and can be allocated by the system, SMS does not migrate them during migration. This reduces how much data needs to be migrated. The migration efficiency is improved.
