Hello, (this is a cross-post from debian-users mailing list https://groups.google.com/d/msg/linux.debian.user/jjdr6LXaOm8/MOoVVo0lAwAJ ) Here is a picture of what I'm trying to achieve: https://imgur.com/a/DAM8D (the "Today" column). I am trying to build a home backup system. The system (Debian Stretch) will be on a SSD. For the time being, I only have one pair of HDDs (the "Today" column in the picture) ; in the future (the "Future" column), I would like to add other pairs of HDD to store other kind of data. This backup system will only be turned on when needed, I don't plan on using it as some sort of server or a NAS. We are talking about software RAID1. I would like everything to be encrypted (FDE), from the system (/ and /swap) to the RAID1 drives. If possible, I would like to have different encryption keys for the system and the various RAID1 pairs (in the "Future" column in the picture, one for the system, one for "work", one for "family", one for "misc"). So that I can give the system encryption passphrase, "family" and "misc" ones to my wife and keep the "work" one for myself. I'm a complete noob when it comes to this kind of operations so I'm looking for a step by step ELI5 explanation (I have tried to use the Debian graphical installer to achieve this but have failed because I was just messing around with the options trying to figure out what to do). Thank you in advance for your help :) CA -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
