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 couldn't sleep at night if I didn't have my data backed up in 6 different places. I spent way too many years as a sysadmin to deal with 2 backups.

ZFS mirrors on my Proxmox server with multiple nodes replicating to each other. Replications of those datasets to zfs.rent. Proxmox backup server taking hourly snapshots and doing it to multiple drives. Rotating USB drives on that PBS server. Backups of the data for each VM and each docker container stack via rsync. Borg backup. Multiple Nextcloud clients with each having their file syncs held locally, then rsynced to a secondary drive.

I could probably come up with a couple more that I've forgotten I have running. I got burned once and it made me mad.
