New york has air rights. Many existing buildings cannot build taller, thus redevelopment removes leasable space instead of modernizing and/or bifurcating it.
Yup. iCloud is just my most recent photos. Once my 200gb starts getting full, I go back and delete photos and videos year by year until i'm down to the last year or two. My entire library is still backed up to a NAS which has offsite backup as well as google photos.
Seems like a smart way to do it, but that relies on having another always-on system standing as the server. OP's solution only requires the one device, the rPi unless something needs to be changed.
If you run an open source router distro like OpenWRT or OPNSense, you can use it as the PXE Boot host. That's a device that needs to be running anyway.
I've seen a lot of people running their routers as a VM on something like Proxmox and that gives you even more flexibility but it does require a beefier server - one that could potentially replace all the RasPis, potentially making the PXE boot redundant. :D
That's true. In theory you could use an extra Raspberry Pi itself as the netboot server. But since my home network already has a fileserver it was an easy choice.
