KLM-AUA: PVE/PBS ERP Operations and Quarterly Reporting

Client background

• In 2024Q3, KLM engaged WalksCloud to maintain the ERP infrastructure used by its end customer KLM-AUA.
• Hardware was provided by KLM and hosted in leased IDC space. ERP vendor responsibility was limited to OS and applications inside VMs; PVE/PBS layers were managed by WalksCloud.
• KLM required stable virtualization, backup continuity, and quarterly reporting suitable for customer audit communication.

Needs and challenges

1. Twice-daily backups: notifications were required for both success and failure to support trend tracking.
2. Clear maintenance reporting: quarterly documentation of PVE/PBS update status and backup posture was required.
3. Boundary control: VM-internal issues remained ERP-vendor scope, while WalksCloud guaranteed virtualization and backup-layer operations.

WalksCloud approach

1. PVE and PBS lifecycle management

• Maintained package updates for both Proxmox VE and Proxmox Backup Server.
• Recorded each update with from-to version evidence and included it in quarterly reports.

2. Daily backup schedule

• Configured PVE backup at 04:30 and 20:30 each day for ERP VMs.
• PBS notification remained enabled for both success and failure outcomes.
• For repeated failures, WalksCloud produced anomaly analysis and mitigation recommendations.

3. Quarterly reporting package

• Delivered report sections including:
  • PVE/PBS update versions and change descriptions;
  • backup success/failure summaries;
  • PBS capacity status and per-VM backup inventory.
• Reports were delivered to KLM for downstream communication with KLM-AUA.

Outcomes

• ERP VMs retained traceable update and backup history suitable for quarterly review.
• Backup operations stayed stable, and exception handling could be triggered quickly from alert notifications.
• WalksCloud maintained low-touch but consistent infrastructure governance over virtualization and backup layers.
