Managed vs Self-Hosted Proxmox Backup Server on a VPS
You can run Proxmox Backup Server on a rented VPS for offsite backups. Or you can use a managed PBS target and skip the server administration. Both get your data offsite. The difference is how much of your time goes into keeping it running.

What Running PBS on a VPS Involves
Installing Proxmox Backup Server on a Debian VPS is the easy part. Keeping it production-ready is where the work lives.
Initial Setup
- Provision a VPS with 2+ cores, 4+ GB RAM, and enough disk space
- Install Debian 12 and add the PBS repository
- Install and configure
proxmox-backup-server - Set up ZFS pool or ext4 filesystem for the datastore
- Configure TLS certificates (Let's Encrypt or self-signed)
- Harden SSH (key-only auth, non-standard port, fail2ban)
- Configure firewall (iptables/nftables, allow only PBS port + SSH)
- Create datastore, users, and API tokens
Ongoing Maintenance
- Apply OS security updates (weekly or via unattended-upgrades)
- Update PBS when new versions release
- Monitor disk space and garbage collection
- Check sync job logs for failures
- Renew TLS certificates
- Monitor server health (CPU, RAM, disk I/O)
- Handle VPS provider maintenance windows and reboots
True Cost Comparison
Raw VPS pricing looks cheaper. But the total cost includes your time and the risk of things you might miss.
Self-Hosted (2 TB, Hetzner CX32)
- VPS (4 vCPU, 8 GB, 80 GB): €8.49/mo
- Additional volume (2 TB): €104/mo
- OR: smaller VPS + Storage Box workaround
Plus 1-2 hours/month for updates, monitoring, troubleshooting. At €50/hr, that's €50-100/month in time cost.
Cash cost: €15-112/mo
Total with time: €65-212/mo
Managed PBS (2 TB)
- 2 TB managed: €17.00/mo
- Setup time: 5 minutes (one-time)
- Monthly maintenance: 0 hours
Includes server-side verification, pruning support, monitoring, and PBS updates.
Total: €17.00/mo
The cash-only comparison at smaller volumes (using a cheap VPS + Storage Box workaround) can favor self-hosting. But the moment you add the value of your time or the cost of an outage caused by a missed update, managed PBS wins on total cost.
When Self-Hosting Makes Sense
Running your own PBS on a VPS is the right call when:
- You want full root access and control over every configuration detail
- You're already managing VPS infrastructure and adding PBS is incremental work
- You need to serve multiple PBS clients (homelabs, friends, small clients) from one instance
- You want to run additional services on the same VPS (monitoring, DNS, VPN)
- You enjoy the learning experience and treat it as a homelab project
- You have 10+ TB of data where per-TB pricing differences compound significantly
If you're comfortable with Linux server administration and already maintain VPS infrastructure, self-hosting PBS is straightforward.
Features You'd Have to Build Yourself
Self-hosting gives you a PBS instance. remote-backups.com gives you a PBS instance plus protection layers that take real effort to replicate on a VPS.
Immutable Backups
A read-only copy with credential separation that survives ransomware and compromised PBS credentials. On a self-hosted VPS, you'd need to set up a second datastore with separate user accounts, restricted permissions, and your own change-timeout logic. Most people skip this step.

Geo-Replication
Automatic replication to separate datacenters every 15 minutes. On a VPS, achieving this means renting a second VPS in a different region, setting up PBS there too, and managing sync jobs between them. Double the maintenance, double the cost.
€4/TB per copy/mo. Learn more
Autoscaling
Automatic storage scaling in 100 GB increments. On a VPS, you resize volumes manually, and most providers require a reboot. Miss a resize and your backups fail silently until you notice.

When Managed PBS Saves You Time
A managed target is the better fit when:
- Backup infrastructure isn't where you want to spend your sysadmin hours
- You want offsite backups working in minutes, not hours
- You don't want to worry about VPS security, updates, or certificate renewals
- Predictable monthly cost matters more than squeezing the lowest per-TB rate
- You need reliable offsite backups for production workloads, not a side project
- Your dataset is under 10 TB and the per-TB premium is small in absolute terms
Set up a sync job with client-side encryption and your offsite backup runs itself. Check our pricing page for current rates.
