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 :)
I agree with Damage, a Docker containers may be more flexible compared to HomeAssistant add-ons. I currently have two Raspberry Pi’s. A Pi4 with a HomeAssistant container and a Pi5 with a simple file server, and a copy of Wikipedia and an unfederated PieFed instance which are all run from containers.
I bought my Pi5 used and it already had a fan installed and judging by how often the fan runs, it seems like a good idea to have. Especially since it’s more powerful compared to the Pi4.
If you’re comfortable working with terminal commands, you could simply use
rsync
for creating and maintaining backups. Works great for remote backups and file systems too. I’ve automated backups for my phone (Android with Termux) both Pi’s and my laptop. All those backups get sent to a partition on my laptop. Then that partition is completely backed up to an external SSD storage. Rsync compares files between the source folder and destination folder so that only the differences are transferred and sends less data. Tools likersnapshot
may simplify the whole process if you don’t have the time or energy to fiddle with rsync.I can share my docker compose file for HomeAssistant and some examples of my rsync commands if that’s a path you’re interested in.
