Backups of Backups (lemmy.today)

Hi all, I'm just getting my feet wet in self hosting and have a plan to start with Nextcloud on a Pi 4 for photo backups, and then try other things for calendar, phone backups, media hosting, etc.

One thing I worry about is losing my data. I have heard "if it's not backed up in two locations, it's not backed up." I'm curious what all of you do for backing up the setup. Remote backup to hard drives in the garage? Pay for cloud backup and encrypt it? Just another backup site over wifi in the house?

I'd be most afraid of losing photos and if there were a house fire or something. So my inital thought was a way of backing up to a server in my detached garage in a weather resistent container, but I want to know what you all think. Thanks for any insight.

I copy my data to a nas at home. That copies once a day to an off-site nas. Once in a while I connect an external disk to the nas and copy all and disconnect it.

Perfect or not, compliant with backup procedures or not ..... it works for me and i'm happy having with an air gap backup.

The only concern I see here is the external drive. My experience has been that powered off drives fail more often than constantly-on drives. So my external drives are always powered on, I just run a replication script to them on a schedule.

But you do have good coverage, so that's a small risk.

I know and I agree. I still want an air-gap backup. Because ......it's air gapped
