Use HomeAssistant as remote "Backup Facility"? (lemmy.ml)

Disclaimer: Backup Facility is probably the wrong word here, but I currently nothing else comes to my mind

My parents would like to have a HomeAssistant. While thinking through the setup in their local network, dynDNS stuff aso., I realized that I could use their open ports to regularly backup my own stuff to there house as remote backup.

Now, as far as I understand, there is no native support for this in HomeAssistant. I just came across the Nextcloud Add-On, which spins up a full Nextclou instance in the background?

If so, my question would be about performance/hardware requirements for ~10 users:

can I run this smoothly on a Pi 5 (8GB)?
or do I need 16GB?
is the standard kit with passive cooling enough, or rather buy active cooling (with a fan?)
is this add-on maintained in a way, that I wouldn't have to worry about critical security bugs, that aren't covered by normal Nextcloud releases?

Thanks beforehand :)

Check out SFTPGo for backups.

Also, I wouldn't open any ports on your parents network other than for something like wireguard

I especially wouldn't expose home assistant to the internet, as it's quite lax on the security front.

As for RAM, 8gig will be more than enough unless they have an ungodly amount of smart devices. I'd stay away from a raspberry pi when deploying to an offsite location, as they're not very reliable long term. Get a NUC or something similar. I just picked up a gmktec n150/12gig soldered on amazon for like $130
