We can backup a CD to a new CD-RW just like backup to a CD-R.

However, if a CD-RW has been used several times and then formatted, a CD can NOT backup to this formatted
CD-RW. Why? Theoretically, a CD-RW is re-writable, so we can theoratically recover a CD-RW to an as-received
state just like a new CD-RW. Why not? How?

I think you are confusing the CD-RW "format" with "erase".  When FORMATTED a CD-RW has a file system
on it called UDF that is used to store data.  UDF (akin to FAT or NTFS) is specially designed for the
problems of doing a read/write filesystem the CD-RW media.  Once you've formatted in UDF the CD-R format
(which is NOT UDF but rather ISO-9660) cannot be written until/unless the CD-RW is ERASED.  This makes it essentially BLANK
and then it is just like new.

Most CD-RW authoring tools have an ERASE feature.
