Is there any way to recover RAID 0?

If you were to have a RAID 0 setup with 4 drives and an external drive for backups, and one drive in the array happens to fail, is there any way you can simply buy a new drive, swap it with the dead one, then copy the old drive's data from your backup external onto the new one, then start your computer like normal?

I know each drive's data is scrambled, because it's cut into pieces. Is there a way to save that scrambled data of each drive onto the external?
