@RustyCrab @JollyWizard okay that's not too bad
for production storage, i'd go for like a 12x LFF 2U server and populate it to start with 6x4TB or 6TB drives in RAID6, ideally with a hot spare too
then pick up a 4x LFF 1U pizza box server, fill it with 4x6TB drives and slap them in RAID5 or ZFS. replicate to that one regularly and automatically.
next, pick up two big fat retard drives and take periodic manual backups to them. don't bother with external drives unless there's significant cost savings, regular old SATA drives you can pop into a hotswap bay are perfect. one goes in your gun safe, one goes in your safe deposit box at the bank or at your mom's house (where i was last night)
