My goal is to create an simple offsite backup of my CasaOS setup using a RasPi 3b+ with external USB drive at a friend’s house. Are there any recommended methods for doing this?

Also: what should I look for in an external hard drive as far as reliability goes for something that will essentially always be on? I’m not well versed in all the WD blue, red, etc. Does it matter?

IMO, a Pi running off a MicroSD card is by far the highest failure risk you have in this configuration.

Yeaaah I know but it’s all I’ve got right now. I plan on keeping a backup image of the microSD image in case it breaks I can just swap it out.

Thanks for the advice! Do you think SyncThing would be the most straightforward way of doing it? I’m running CasaOS for most apps but have HA in a virtual machine.

Try one of those endurance micro SD cards, since you dont need a lot of storage for OS they should be pretty cheap like 32gb is like $12.

Great to know about, thanks. SanDisk has 64gb for $10 on Amazon (32gb for $12 lol)

May be worth doing backups with something like rsnapshot. That way you’ll have history in the event of any data corruption.
