Selfhosted

I use Borgmatic for my scheduled backups, and sync to Backblaze B2 with Rclone. Works great!

My data doesn't compress as well as yours though.

restic also written to do what borg does but fix a bunch of the shortcomings that they also now fixed (many of) in the new 2.0/2.x versions

I use self hosted borg repo to backup to a local server and then also borgbase is a service that allows remote backup.

Borgmatic automates all of this.

I looked at Borg, didn't see a GUI, but Borgwarehouse look good. It's on the list. Thanks

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:

#!/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.

I run Proxmox on the local server. I didn't know Veeam had a community edition. The 13 gb download just finished. It's on the list. Thanks.

Veeam community edition is fine for most things.
If you are cheeky, generate yourself an NFR license on their website.

Edit: Veeam plans a Linux version for VBR 13.
Veeam Agent can run stand-alone on both Linux (only specific distros are actually supported. Non-supported might work) and Windows
