I haven’t noticed anyone else bring it up, but you mentioned in passing the possibility of using a RAID 0. I’d avoid that except in very specific circumstances. They’re potentially fine for a scratch disk type of scenario, but if any member of the array fails, the whole array is toast. The chances of a failure increases with was each disk added, so a RAID 0 is less reliable than a single disk. I definitely wouldn’t want to trust my family’s photos to it.

I run 120TB on a VM with 2 cores and 2gb of ram. Data storage is not very hardware intensive. Now serving the data to dozens of users is where you're going to have issues.
Number of users total isn’t a big deal, number of concurrent users is. If nobody’s accessing them often it’s not particularly hard on your hardware either
Sorry for my bad English btw
I backup to Backblaze B2 (6$/TB a month), but I have much less data. I also backup all my data to another disk that lives in the same server. Id probably continue doing manual backups to external drive due to the cost of cloud backups
Cloud question:
Hetzner Storage Boxes.
Supports Snapshots. Create one every Day the last 30 days. Ez way to have another way of rolling back older backups.
Got 10TB available for ~24€.
Sync up there with rSync Protocol.
To be fair I am backing up from a Synology NAS so I am playing this in EZ-Mode :D
Don't know how easy this is to setup on nextcloud.
