Backup management
PBS jobs and retention monitored, restore tests by agreement.
Operations logs and documentation
Logs retained immutably, changes documented.
Response by service level
Incidents within the agreed response targets.
Personal point of contact
Knows your environment, coordinates with provider or hardware partner.
How Proxmox Management Starts
Assess the current state, confirm the scope, and transition into ongoing operations in a controlled manner.
- 01
Record the Current State

- 02
Define the Operating Scope
Confirm responsibilities, maintenance windows, and service level
- 03
Connect Monitoring
Set up checks, alert paths, logs, and documentation

What a Proxmox maintenance cycle actually includes
From update to report, the same in every cycle.
PVE updates in the cycle
Minor updates in the agreed maintenance window, patches for critical vulnerabilities brought forward.Major upgrades planned
Such as PVE 8 to 9: assessed in advance, confirmed as a separate scope, with a rollback path.Ceph version maintenance
Aligned with PVE version, cluster health and redundancy where Ceph is in scope.PBS and backup checks
Jobs, retention, prune, GC and verify checked; restore tests by agreement.Report per cycle
Applied updates, anomalies, backup status and recommendations at a glance.Cycle start24/7 proactive monitoringReport
After each cycle you receive a compact report. Major upgrades such as PVE 8 to 9 are planned as a separate scope, with dependencies and a rollback path.

Answers to the most important questions
- At WZ-IT, Proxmox maintenance forms part of Managed Proxmox. It includes 24/7 proactive monitoring, regular PVE, kernel, and package updates, CVE and advisory monitoring, backup management, immutable operations logs, documentation, and incident response according to the agreed service level. Restore tests, specific RTO/RPO, and major upgrades are explicitly agreed where required.
- At WZ-IT, Proxmox maintenance, Proxmox management, and Managed Proxmox lead to the same ongoing operations service. It starts at €179.90 net per node and month. The calculator on the Managed Proxmox page provides a non-binding guide price; clusters, Ceph, recovery objectives, and the condition of an existing environment are reviewed technically.
- Update frequency and maintenance windows are agreed for the environment. Regular PVE, kernel, and package updates follow that schedule. For critical vulnerabilities, we assess exposure, available mitigations, and operational risk, then prioritise a suitable patch or mitigation path.
- Major upgrades are technically assessed in advance and confirmed as a separate scope. We record dependencies, review the backup and rollback path, and check the compatibility of Ceph, PBS, and other components. The process and possible interruptions depend on architecture, capacity, and workloads.
- We assess the specific exposure, available patches or mitigations, and operational risk. Any required change is prioritised, coordinated, and documented through the agreed change and escalation path; the response target and further incident work follow the service level.
- Relevant incidents receive a technical initial response according to the agreed service level. We assess the alert, initiate the agreed actions, and coordinate other parties such as the hardware or infrastructure provider where required. The scope of subsequent remediation follows the contract.
- No. Proxmox VE is open source and can be operated without an enterprise subscription. A subscription adds the enterprise repository and, depending on tier, vendor support. Our managed operations cover ongoing operation. WZ-IT is an Authorized Reseller of Proxmox Server Solutions GmbH; subscriptions can be purchased through WZ-IT. We recommend a paid tier for production; we also operate environments without a subscription.
- We monitor CPU, RAM, disk I/O, network, RAID/ZFS status, Ceph health, VM status, and cluster quorum around the clock. We respond proactively to relevant anomalies according to the agreed service level.
- Maintenance mode supports planned work on HA cluster nodes. Whether guests can be live-migrated and continue without interruption depends on storage, networking, remaining capacity, and the individual workload. We assess these prerequisites when planning the maintenance window.
- Proxmox documents `apt update` followed by `apt full-upgrade`, or the web interface. We check repositories, backups and cluster health, plan the maintenance window and verify the environment after updating. Major upgrades are agreed separately. Proxmox documentation
- Costs depend on CPU sockets and tier. WZ-IT is an Authorized Reseller of Proxmox Server Solutions GmbH. The cost overview and subscription service explain prices and purchasing.
- A subscription covers the enterprise repository and, depending on tier, vendor software support. The maintenance contract governs monitoring, updates, backup management and incident response by WZ-IT. These services are agreed separately.

Reviews & projects
Proxmox proof from real projects
Customer feedback on virtualization, backup, VPN, security and ongoing cluster operations.
WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.
