Ironcore Backup Solution Admin Guide

Overview

Ironcore Backup Solution (IBS) is the platform-wide service for backing up and restoring compute instances, system containers, and physical hosts. As an administrator you provision backup datastores, configure retention policies, define replication targets, integrate tape libraries and object storage backends, and govern access through roles and tokens. This guide covers the full administrative lifecycle — initial deployment, day-to-day operations, and tuning IBS for production workloads.

All operations in this guide require administrator privileges. Changes to retention policies, datastore configuration, and replication jobs affect data already protected. Validate every policy change against the Prune Simulator before applying.

Deployment Console
CLI

Open the Deployment Console

Enable Backup Solution

Select the Advanced Features tab. Toggle Enable Backup Solution to Yes.This provisions the backup server, default local datastore, and the integration with the Ironcore platform without any manual file editing.

Save and Deploy

Click Save Configuration, then go to Operations and run deploy or reconfigure.

The IBS service starts. The default datastore is registered and reachable via the Dashboard.

Enable IBS by setting the flags in the globals configuration and deploying.

Create IBS globals override

cat > /etc/ironcore/globals.d/_50_backup.yml << 'EOF'
enable_backup_solution: "yes"
backup_default_datastore: "ibs-primary"
EOF

Deploy the Backup Solution service

ironcore-ansible deploy -t backup

The IBS API, scheduler, GC worker, and verification worker are running on all backup nodes.

In This Guide

Architecture

Component diagram, data flow, change tracking, deduplication, and encryption layers.

Datastores

Create local, replicated, and S3-backed datastores. Organise data into namespaces.

Retention Policies

Configure daily, weekly, monthly, and yearly retention with the Prune Simulator.

Replication and Sync

Replicate backups between Primary DC and Backup sites with encryption in transit.

Tape and Object Storage

Integrate LTO tape libraries and S3-compatible object storage for long-term archival.

Access Control

Roles, API tokens, multi-factor authentication, and LDAP / Active Directory realms.

Security and Encryption

Client-side AES-256-GCM, master-key handling, ransomware protection, and hardening.

Verification and Validation

Schedule integrity checks and conduct bi-annual mock recovery drills.

Notifications

Send alerts via SMTP, webhooks, and external metric servers.

Infrastructure Sizing

Plan Primary and Backup site capacity for incremental, full, and archival retention.

Troubleshooting

Diagnose backup, restore, sync, and verification failures across the stack.

Architecture Summary

Service	Role
Backup API	REST API for backup, restore, datastore, and job management
Scheduler	Triggers backup, sync, and verification jobs based on configured schedule
Garbage Collector	Reclaims chunks that no snapshot still references
Verification Worker	Re-reads chunks and recomputes SHA-256 to detect bit rot
Replication Worker	Mirrors snapshots from Primary to Backup site over an encrypted channel
Tape Worker	Reads / writes LTO tapes; manages barcoded media catalog

Compliance Mapping

Requirement	IBS Capability	Configured In
Block-level change tracking (CBT)	Native block-level CBT for running VMs	Architecture
Full + incremental + file-level restore	Snapshot model with mountable archive	Restore Options
Daily Incremental retention (7 days)	Retention policy `keep-daily=7`	Retention Policies
Weekly Full retention (3 weeks)	Retention policy `keep-weekly=3`	Retention Policies
Weekly archival (52 weeks) at Backup site	Sync job + retention `keep-weekly=52`	Replication and Sync
Near real-time async replication	Push / pull sync jobs with throttling	Replication and Sync
Encryption in transit	TLS 1.3 between sites	Replication and Sync
Integrity verification of replicated data	SHA-256 verify after sync	Verification and Validation
Deduplication and compression	Content-defined chunking + Zstandard	Architecture
Encryption at rest	Client-side AES-256-GCM	Security and Encryption
Role-based access control	Roles, API tokens, restricted-by-default	Access Control
Immutability against modification	Append-only chunks, no chunk rewrite	Security and Encryption
Bi-annual mock drill	Restore-test job from Backup site	Verification and Validation
