The idea is freshing but doesnt seems right and still the best way to back up wallet.DAT file is still the use of multiple storage media which will be keep in safety deposit box.

Agreed, but some people might want to add a paper backup to traiditional backup methods. You shouldn't rely solely on this program to back up your wallet.dat file, but it might be useful when all else fails.
This program isn't meant to replace backing up to different storage media such as CDs, DVDs, BDs, USB sticks and HDDs, SD cards, cloud storage but rather to complement them.
