Please ask man page for details.

In short, xfsdump is used to perform an incremental dump of an XFS file
system.  corresponding, xfsrestore is used to restore the file system back
from the dumps.

xfs_metadump/xfs_mdrestore are used to dump/restore filesystems metadatas,
but they are used for debug purpose only.

Thanks,
