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.

every VM with state backs up its state to the NAS once a day
client devices rsync most of their home folder to the NAS once an hour
at 3:15 in the morning, a Borg backup job starts pushing the days changes to a Hetzner storage box

Through borg, I have the Option to go back to any point in time with the backups. I will probably never need this, hence why it happens in this step, not on the rsync job to the NAS.

Things like movies and tv shows are not backed up, they are replaceable. All in all, about 2tb of documents, pictures, and VM state is backed up to Hetzner, out of the 16tb on the NAS.

Pick and choose your battles.

For stuff like movies I simply use replication as my backup.

Since I share media with fruends/family, I act as the central repository and replicate to them on a schedule (Mom on Monday, Friend 1 on Tuesday, etc), so I have a few days to catch an error. It's not perfect but I check those replication logs weekly.

I also have 2 local replicas of media, so I'm pretty safe.
