Backup questions

[kyprime22]

I'm confused about the details of this process, so I have a few questions

1. why would I ever use the no decryption option?
2. when I rip a file from the disc, the quality of video/audio is supposed to be 1:1, is this the same for backups? I can use the backup to extract raw complete quality files and is it the same for non decrypted and decrypted backups?

1. if a key was not avaliable at the time you could decrypt it later when there is without ripping the disc again
2. yes 1 to 1 makemkv never compresses anything it all comes off as it is on the disc from what you select
