    Are your Proxmox backups truly safe?

    Your backups are on the same server as production

    Disaster = everything lost. The OVH SBG2 datacenter fire destroyed 30,000 servers in one night — production and backups together.

    Ransomware also encrypts your local backups

    Attackers target backups first. Without immutable backup, restoration is impossible.

    You manage your PBS manually

    No monitoring, no alerts, no automatic verification. You'll discover the backup failed... when you need to restore.

    Offsite managed Proxmox backup — automatic and immutable

    Native PBS

    Zero agent, zero client configuration. Your managed PBS in the cloud works with your existing Proxmox VE — simply add a remote datastore. For Linux servers outside Proxmox, the proxmox-backup-client writes to the same datastore, from RHEL, Alma, Arch or Alpine just as from Debian.

    Offsite

    Our datacenters in France and the EU, physically separated from your production. RDEM Systems private network (AS206014).

    Immutable

    Tamper-proof backups during the retention period. PBS snapshots allow restoring a point prior to an attack.

    Air-gapped (option)

    Disks physically disconnected from the network. Maximum ransomware protection, ANSSI calls an offline backup indispensable (R12).

    Sovereign

    Hosted in the EU (France on request). Helps with GDPR compliance and provides the building blocks NIS2 expects. No transfer outside EU by default. Optional client-side AES-256 encryption.

    1

    Add the datastore

    Add our PBS as a remote datastore in your Proxmox VE. We guide you step by step.

    2

    Configure your jobs

    Scheduling, retention, verification. Everything is done from the Proxmox VE interface you already know.

    3

    It's automatic

    Your VMs are backed up automatically. Monitoring and alerts included — we watch, you sleep.

    The first full backup depends on your volume and connection: calculate your window from your uplink before scheduling your jobs.

    Frequently asked questions about Proxmox backup

    Thanks to PBS native deduplication, only modified blocks are transferred after the first full backup. A 100 Mbps connection is sufficient for most infrastructures. For the initial backup of large volumes, we can provide a physical disk for direct import (seed).

    Duration depends on volume and bandwidth. For 1 TB on a 1 Gbps connection, expect about 3 hours. For another volume or another speed, use our download time calculator. Subsequent backups are block-level incremental and take only a few minutes.

    From the Proxmox VE interface, select the NimbusBackup datastore, choose the desired snapshot and start the restore. On disk-based plans the data is online, so the restore starts immediately; its duration depends on your volume and your bandwidth. We do not commit to it contractually, we measure it during accompanied tests. Our team can assist you in case of emergency.

    Yes, if you enable it: client-side AES-256 encryption is configured in Proxmox VE, and your data is then encrypted before it leaves your infrastructure, with a key only you hold; we then never have access to your data in clear text. In every case, it travels through an encrypted tunnel. We recommend enabling this option.

    In our own Equinix Paris racks (RDEM Systems private network, AS206014) or on servers rented from major French or European hosting companies (such as OVH). No transfer outside EU by default; hosting in France on request; a US datastore on express request: transfer outside the EU governed by the contract, exposed to US law (Cloud Act). Helps with GDPR compliance and provides the building blocks NIS2 expects.

    Yes, NimbusBackup is compatible with Proxmox VE 7.x, 8.x and 9.x. The PBS protocol is native — no agent to install. Simply add our PBS as a remote datastore.

    A local NAS is on the same site as your production: in case of fire, flood or ransomware, everything is lost together. NimbusBackup is offsite in a remote datacenter, with immutability and air-gapped options. That's the difference between a backup and real protection. If you actually have a NAS to offsite (Synology, QNAP…), the Gateway handles it; to weigh the ingestion methods, see the guide.

    An air-gapped backup is physically disconnected from the network. At NimbusBackup, 2 disks stay offline at all times, with a guaranteed monthly rotation: you always hold 2 months of backups disconnected from the network. Ransomware cannot reach a medium that is not connected to anything. Learn more: complete air-gapped guide.

    A managed PBS in the cloud eliminates the maintenance, monitoring, and updates you would have to manage yourself with a local PBS. Most importantly, it provides physical separation from your production: in case of disaster on your site (fire, ransomware), your backups are intact in a remote datacenter. That's real Disaster Recovery. Learn more: Managed Proxmox Backup.

    Yes, for small volumes we can assist you with a free setup. Contact us to get your PBS credentials and evaluate the service on your actual infrastructure.
