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.

At the moment I’m doing primarily hopes and prayers

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.

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

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.

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.

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

At home I have a Synology NAS for backup of the local desktops. Offsite Backups are done with restic to Blackblaze B2 and to another location.

Desktop: I was using Duplicati for years but I’ve recently switched to Restic directly to B2. I’m using this powershell script to run it.

Server: I’m also using restic to b2.

I also have a Qnap NAS. I’m synchronizing my replaceable data to crappy old seagate NAS locally. For the irreplaceable data that’s using the Qnap backup client to B2.

veeam is pretty simple and powerful, the community version is free if you are only using it for a small environment (CPU cores is what it counts)

I havn’t used it for docker but it says it is supported

I run a second Unraid server with a couple of backup-related applications, as well as Duplicati. I have my main server network mounted and run scheduled jobs to both copy data from the main pool to the backup pool, as well as to Backblaze. Nice having the on-site backup as well as the cloud based.

I occasionally burn to 100gb blurays as well for the physical backup.

Backblaze B2. Any software that is S3 compatible can use B2 as the target and it’s reasonably priced for the service. I backup all the PCs and services to a Synology NAS and then backup that to B2 (everything except my Plex media, that would be pricy and it’s easy enough to re-rip from disc if needed).

Rsnapshot to an external USB drive.

Probably not the best, but it works for my little 6TB OpenMediaVault server with some Docker thrown in.

I use kup to back up my important PC files (the basic pre-installed backup software on KDE neon), which backs up to a separate drive on my PC, and that gets synced to my Nextcloud instance on my local server, and that - along with all the other data for my containers running on it - gets backed up by Kopia to DigitalOcean spaces.

I couldn’t recommend Kopia strongly enough, because you have such fine control of what gets backed up, when it gets backed up, how many to keep etc. and it is versioned so doesn’t grow exponentially, and it compresses and encrypts the backup. I also have a setup where it executes a script before and after the backup starts that stops and starts the containers to maintain file integrity since nothing will be writing to the files. And it’s also a Docker container so it can just fit into your current compose setup.
