I'm really new to this topic, so big apology for stupid questions.

I have a school project and I want to know how to store 250TB of data with life-cycle for 18 months. It means every record is stored for 18 months and after this period of time can be deleted.

There are 2 issues:

store data
backup data

Due to amount of data I will probably need to combine data tapes and hard drives. I'd like to have "fast" access to 3 month old data, so ~42TB on disk. I really don't know what RAID should I use, or is here any better solution than combining disk and data tapes?

Thanks for any advice, article, anything. I'm getting lost.
