I've been looking into doing something similar for an offsite backup for my extensive photo collection- how much storage do you have and how much did it cost you?
$280 with separate drives - https://www.amazon.com/Synology-DS416slim-NAS-DiskStation/dp...
One very cool part is it has sync software that can automatically sync all or some of your stuff - one way or bidirectional - to dropbox, google drive, backblaze, amazon glacier etc for backups and public access.
There's a fork of their software here to install on other devices too - https://xpenology.me
It's not a fork so much as a custom bootloader for Synology's version of Linux.
