¶ Backup and Recovery Policy for package−client
This document outlines the backup and recovery strategy for package−client. The purpose of this policy is to ensure the confidentiality, integrity, and availability of package−client's data through a multi-tiered backup strategy. This strategy is designed for rapid recovery and resilience against data loss, corruption, ransomware, and operational failures.
This policy applies to all production systems, data, and services managed by or on behalf of package−client. This includes but is not limited to customer data, application logs, configuration data, and infrastructure as code.
- Rolling Snapshots: Automated rolling snapshots are configured for all production MariaDB instances containing package−client data. Snapshots are retained according to defined Recovery Point Objectives (RPOs) and support point-in-time recovery.
- Immutability Controls: IAM policies are enforced to restrict deletion and modification of snapshots. Integration with AWS Backup and Object Lock ensures compliance-grade immutability for critical data.
- Snapshot Strategy: Backups of MongoDB databases holding package−client data are performed using logical dumps and filesystem-level snapshots. These backups are encrypted and stored in secure S3 buckets and on NAS volumes.
- Retention: Tiered retention policies are in place to ensure daily, weekly, and monthly restore points are available.
- Transport Security: All backup data is transmitted over TLS to internal Network Attached Storage (NAS) volumes to ensure confidentiality during transit.
- Storage Controls: NAS volumes are configured with write-once access policies. Filesystems such as ZFS or Btrfs are utilized to support immutability flags, preventing tampering or premature deletion of backup files.
- Restore Testing: Periodic restore tests are conducted to validate the integrity and bootability of Proxmox VMs and service containers from NAS backups.
- Encryption: All backups are encrypted at rest using AWS-managed keys or, where applicable, package−client-specific KMS keys for enhanced security.
- Object Lock: For high-compliance deployments, S3 Object Lock is enabled in compliance mode. This prevents any overwrite or deletion of backup data during the defined retention window.
- Local Backup Strategy: For any on-premise deployments, encrypted backups are stored on isolated volumes. package−client may optionally enable immutability using ZFS snapshots or other third-party backup tools.
- Security Hardening: On-premise systems are deployed with pre-configured firewall rules (UFW), a ModSecurity Web Application Firewall (WAF), and local MQTT telemetry for anomaly detection.
- Restore Workflow: Backup restoration is validated using checksum comparison and service-level smoke tests to ensure data integrity.
- Restore Testing: Restore workflows are tested on a quarterly basis across all environments. These tests include snapshot rehydration, service boot validation, and data integrity checks to ensure backups are viable for recovery.
- Telemetry Integration: All backup events (e.g., success, failure, anomalies) are published to an MQTT topic and stored in InfluxDB for auditing, and alerting.
- Alerting: Threshold-based alerts are configured to notify the operations team of missed backups, degraded snapshots, or restore failures, ensuring prompt investigation and remediation.
- Reporting: Dashboards are maintained to provide visibility into the status of backups and the overall health of the backup process.

This strategy ensures that all of package−client's backups are secure, recoverable, and resilient against ransomware, while supporting both cloud and on-premise deployments.
This policy will be reviewed annually, or in the event of significant changes to the infrastructure or business requirements of package−client, to ensure its continued effectiveness.
