Thank you. I need to start small, otherwise I feel overwhelmed by too many moving pieces to keeo in mind and plan for. So I'm starting small, from powering up a ThinkCentre M910 I had laying around, with an internal disk that can be used to store backups. I have 0 need for performance so my idea was to extend storage with an external USB3 HD enclosure. For now, I don't have the space nor the machine where to install dual hard disks for building a decent RAID. Time will tell.
