Best Back Up Solution For Multiple Servers (lemmy.world)

submitted 2 days ago by [email protected] to c/[email protected]

13 comments fedilink hide all child comments

So, I run three VPS and one rack in the closet. Currently I have Duplicati running on all four servers. What I would like to do is have one central server back up all four servers and store the backups in an offsite repository.

I'd prefer something with a good GUI. I know you purist get a hard on thinking about the CLI, and while it is a very powerful aspect of Linux, I still like a GUI.

What are my options?

Side note, I wanted to look at Bacula but their site seems nonexistent. Is Bacula defunct?

I’ve been quite happy with Proxmox Backup Server. I’ve had it running for years and it’s been pretty solid for all my VMs/containers. There’s also a bare metal client, which I’m adding to a couple cloud VPS machines this weekend. We’ll see how that goes.

Also, since it’s just Debian under the hood, I also use the PBS host as a replication target for my ZFS datasets via sanoid/syncoid.

Will Proxmox BackUp server handle remote VPS? I had assumed that it only was for ProxMox VM's.

Backup Types: Proxmox Backup Server is optimized for backing up Proxmox VMs and containers. If your VPS is running a different virtualization platform, you may need to adapt your backup strategy accordingly.

That's what AI tells me and then gives a configuration such as:

spoiler

#!/bin/bash

# Variables
CONTAINER_NAME="your_container_name"
VOLUME_NAME="your_volume_name"
BACKUP_DIR="/path/to/backup/dir"
TIMESTAMP=$(date +"%Y%m%d_%H%M%S")

# Create a backup of the Docker volume
docker run --rm -v ${VOLUME_NAME}:/volume -v ${BACKUP_DIR}:/backup alpine \
    sh -c "cd /volume && tar czf /backup/${VOLUME_NAME}_${TIMESTAMP}.tar.gz ."

# Optionally, export the container
docker export ${CONTAINER_NAME} -o ${BACKUP_DIR}/${CONTAINER_NAME}_${TIMESTAMP}.tar

echo "Backup completed for ${CONTAINER_NAME} and ${VOLUME_NAME} at ${TIMESTAMP}"

Yeah I know it's AI, which may or may not be completely accurate. Would I need to do that for each and every Docker container? I've got some 60 +/- containers. LOL <whine boohoo!>

That along with the client on the remote VPS would take care of Docker containers, however, I would also like to back up configuration files, and data associated with UFW, F2B, etc. Pretty much a snapshot of each server.

These lowendbox hosts don't include snapshots and frills and Contabo only lets you keep one snapshot active. I did find an N8N flow that automates the snapshot process for Contabo. I guess I could upgrade to better hosts, but one of the VPS is my skunk works server where I run and test everything before putting it into production...it's like $25 per year. Contabo is decent, and LuxVPS gives me the most bang for buck including all the frills for $10 a month. So, that's about as much fun money I got for the time being.

It sure will handle a remote VPS, it’s just not as automatic to set up as it is with PVE.

I put this off for a long time, but I finally did it this weekend.

Basically, you install the proxmox-backup-client utility and then run it via cron or a systemd timerto do the backup however often you want.

You’re responsible for getting the VPS to communicate with your backup server (like pretty much any self-hosted service), so some sort of VPN between them would be good. I used NetBird for that part and I have a policy that allows access from the client to PBS only on TCP port 8007.
