At the moment I’m doing primarily hopes and prayers

I’ve been using Borg to back my stuff up. It gets backed up to rsync.net, which has good support for Borg:

If you’re good enough at computers, you can even set up a special borg account with them that’s cheaper and has no tech support.

Local backup to my Synology NAS every night which is then replicated to another NAS at my folks house through a secure VPN tunnel. Pretty simple and easy to deploy.

I’ve had excellent luck with Kopia, backing up to Backblaze B2.

At work, I do the same to a local directory in my company provided OneDrive account to keep company data on company resources.

Restic for backup - can send backups to S3 and SFTP amongst other target options.

There are S3 (block storage) compatible services, such as Backblaze’s B2, which are very affordable for backups.

For app data, Borg as backup/restore software. Backup data is then stored on Hetzner as an offsite backup - super easy and cheap to setup. Also add healthchecks.io to get notified if a backup failed.

Edit: Backup docker compose files and other scripts (without API keys!!!) with git to GitHub.

Someone on lemmy here suggested Restic, a backup solution written in Go.

I back up to an internal 4TB HDD every 30 minutes. My most important files are stored in an encrypted file storage online in the cloud.

Restic is good stuff.

I doubt your using NixOS so this config might seem useless but at its core it is a simple systemd timer service and bash scripting.

To convert this to another OS you will use cron to call the script at the time you want. Copy the part between script=“” and then change out variables like the location of where docker-compose is stored since its different on NixOS.

Let me explain the script. We start out by defining the backupDate variable, this will be the name of the zip file. As of now that variable would be 2023-07-12. We then go to each folder with a docker-compose.yml file and take it down. You could also replace down with stop if you don’t plan on updating each night like I do. I use rclone to connect to Dropbox but rclone supports many providers so check it out and see if it has the one you need. Lastly I use rclone to connect to my Dropbox and delete anything older than 7 days in the backup folder. If you end up going my route and get stuck let me know and I can help out. Good luck.

    };

I use restic (and dejadup just to be safe) backing up to multiple cloud storage points. Among these cloud storage points are borgbase.com, backblaze b2 and Microsoft cloud.

VM instances on the Proxmox VE with native integration with the Proxmox Backup Server (PBS).

For non-VM a little PBS agent.

I use Backblaze B2. I was using AWS S3 but the Backblaze pricing is significantly better.

I host everything on Proxmox VM’s so I just take daily snapshots to my NAS

my 20 TB storage is currently hosted by Hetzner on a SMB Share with a acompanying server The storage is accessable via NFS/SMB i have a Windows 10 VPS running Backblaze Personal Backup for 7$/Month with unlimited storage while mounting the SMB share as a “Physical Drive” using Dokan because Backblaze B1 doesn’t allow backing up Network shares If your Storage is local you can use the win Backup Agent in a Docker container

raid1 + data duplication

Photos, videos, music, documents, etc… are available on multiple devices using SyncThing.

So far I have had good experience with kopia. But it is definitly less battle-tested than the other alternatives and I do not use it for too critical stuff yet.
