[Question] How do you handle offsite backups for your setup? (lemmy.ml)

I'm particularly interested in low bandwidth solutions. My connection to the internet is pretty rough 20mbps down and 1mbps up with no option to upgrade.

That said, this isn't limited to low bandwidth solutions.

I'm planning on redoing my entire setup soon to run on Kubernetes followed by expanding the scope of what my server does (Currently plex, a sftp server and local client backups). Before i do that i need a proper offsite backup solution.

@[email protected] Remote backups might be rough with that upload speed. For example, you will be looking at over 2 hours per GiB uploaded.

I personally have a 3 node setup using kubernetes and I run longhorn for volume management. I do hourly snapshots, and then daily backups of all volumes to an additional drive on one of my 3 nodes with a simple NFS server which is also running in kubernetes. In longhorn I keep 2 replicas of every volume as well so losing one doesn't hurt anything.

I would imagine it would be pretty easy in this case to replace my local NFS with AWS storage and then I would have remote backups, but since I back up roughly 100 GiB per day that would be a little time consuming. At my 50 Mbps that's about 4.5 hours, though remote backups could be done less often as a last resort backup.

Yeah it is pretty rough although the files don't necessarily change all that much so if i can set up a backup somewhere and prepopulate it with my data as it stands now then incrementally keep it update it with nightly jobs then i'm hoping it'll mostly be done by the morning.

My backup backup plan would be to buy a couple high capacity solid state disks and either take them myself or mail them to my parents once a week. The mailman has pretty high bandwidth, even if the latency is rather rough
