The blu rays work but the backup internal is to long. It really needs to be done every hour. Hourly backup is best done with a hard drive.
A simple and painless way is to subscribe to a service. The guys who run the the big cloud can buy storage cheaper then you can and they have peta-bytes and do all the maintenance and upgrades for you. One problem with using small media is that to restore it you have to know a lot. Typically each disc is only the delta from a full snapshot so to restore you first restore the last ful image then you have to restore each change disc.
