I’m currently using an RPi 4 with 1GB RAM to mess around with HAOS and experiment, intending to move to more capable piece of hardware when I move home in May, to set up an actual smart home hub.
One topic I am yet to consider is backup of the system, as if it goes down I would really need it to be back up ASAP. Couple of questions for the more experienced than me:
- I’m currently using an SD card, and I understand the limitations with this but the simplicity makes it pretty attractive for where I am at. Is it possible to backup the SD card with the HAOS system on it to another SD card, such that if the original card fails I can simply pop it out and pop the backup one in?
- If go the route of using an SSD connected via USB/SATA, and configure to boot from USB, is it possible to backup the SSD with the HAOS system on it to another SSD, such that if the original drive fails I can simply connect the backup drive via USB to the same port?
If neither of these is possible, how involved is the restore process?
Ideally, what I’m really looking for here is some sort of redundancy/failover, but in the absence of running parallel instances (which is beyond my capability I think), I’m trying to figure out what the easiest restore process would be. Something that I could theoretically get my other half to do if given instructions over text would be the north star here.
