Oxidized Backup Tool: Complete Configuration Backup Guide for Modern Network Engineers (2026)

Introduction

Network infrastructure has undergone a significant transformation over the last decade. Modern enterprises operate highly distributed environments consisting of branch offices, campus networks, data centers, cloud platforms, SD-WAN deployments, wireless infrastructures, and security appliances from multiple vendors.

As networks become more complex, configuration management becomes increasingly critical.

A single unauthorized configuration change can introduce security vulnerabilities, trigger application outages, disrupt routing paths, create compliance violations, or impact business operations. While many organizations invest heavily in monitoring, observability, and cybersecurity, configuration backup is often overlooked until a major incident occurs.

Unfortunately, recovering a device without a recent backup can become a lengthy and costly process.

This is where Oxidized provides tremendous value.

Oxidized is an open-source network configuration backup and version-control platform that automatically connects to network devices, retrieves configurations, tracks changes, and stores backups in a centralized repository. By integrating with Git and supporting hundreds of network device models, Oxidized enables organizations to automate one of the most important operational tasks in network management.

Whether you manage ten devices or ten thousand, automated configuration backups are no longer optional. They are a fundamental requirement for operational resilience, compliance, change management, disaster recovery, and network automation.

In this guide, you will learn how Oxidized works, why it has become the preferred alternative to legacy solutions, how its architecture operates, and how to deploy it successfully in modern enterprise environments.

What Is Oxidized?

Oxidized Definition

Oxidized is an open-source network configuration backup and configuration management tool designed to automatically collect, store, and version-control network device configurations.

The platform connects to network devices using SSH or Telnet, retrieves configuration data using vendor-specific commands, processes the output, and stores backups in Git or other supported storage backends.

Unlike traditional backup solutions that simply save configuration snapshots, Oxidized provides complete configuration history through version control. This allows engineers to identify exactly what changed, when the change occurred, and how configurations evolved over time.

In practical terms, Oxidized transforms network configuration management into a modern Git-based workflow similar to the practices used by software development teams.

Key Functions of Oxidized

Oxidized performs several critical tasks automatically:

• Device discovery and inventory integration
• Secure SSH-based configuration collection
• Automated backup scheduling
• Multi-vendor configuration management
• Git-based version control
• Configuration change tracking
• Historical configuration storage
• Configuration drift detection
• Web-based configuration viewing
• API-driven integrations

These capabilities make Oxidized a foundational component of modern NetDevOps and network automation strategies.

Why Was Oxidized Created?

Before Oxidized became popular, many organizations relied on RANCID (Really Awesome New Cisco Configuration Differ) for automated configuration backups.

While RANCID was revolutionary during its time, modern networks demanded:

• Better scalability
• Cleaner architecture
• Git integration
• API capabilities
• Modern automation workflows
• Improved multi-vendor support

Oxidized was developed to address these limitations while maintaining the core functionality network engineers required.

Today, many organizations view Oxidized as the natural successor to traditional network backup platforms.

Key Features of Oxidized

Why Network Engineers Need Automated Configuration Backups

The Problem with Manual Configuration Management

Many network teams still rely on manual backup processes.

A typical workflow often looks like this:

1. Log into a device.
2. Run a configuration command.
3. Copy the output.
4. Save it to a local file.
5. Repeat for dozens or hundreds of devices.

This approach introduces multiple risks:

• Human error
• Inconsistent backups
• Missing configurations
• Lack of version history
• Poor auditability
• Increased operational overhead

As environments grow, manual processes become unsustainable.

Common Causes of Network Outages

Configuration changes remain one of the leading causes of network incidents.

Examples include:

• Incorrect VLAN assignments
• Routing policy mistakes
• BGP configuration errors
• Firewall rule changes
• ACL modifications
• Interface misconfigurations
• QoS policy issues

Without reliable backups, recovering from these incidents becomes significantly more difficult.

Real-World Recovery Scenario

Imagine a core switch fails unexpectedly.

The replacement hardware arrives, but no recent configuration backup exists.

The network team must reconstruct:

• VLAN databases
• Trunk configurations
• Routing protocols
• Access control lists
• Security policies
• Quality of Service configurations

This process may take hours or even days.

With Oxidized, engineers simply retrieve the latest configuration from Git and restore the device.

Recovery times are dramatically reduced.

Benefits of Automated Configuration Backups

Faster Disaster Recovery

Backup availability accelerates restoration efforts during outages and hardware failures.

Reduced Downtime

Organizations can restore services more quickly when configurations are readily available.

Improved Compliance

Many regulatory frameworks require configuration retention and change tracking.

Examples include:

• PCI DSS
• ISO 27001
• SOC 2
• HIPAA
• NIST Cybersecurity Framework

Version-controlled backups provide valuable audit evidence.

Better Change Management

Teams gain visibility into:

• Who made changes
• What changed
• When changes occurred
• Whether changes were approved

Enhanced Security

Unauthorized modifications become easier to detect through historical comparison.

Increased Operational Efficiency

Automation eliminates repetitive backup tasks, allowing engineers to focus on strategic initiatives.

Understanding Configuration Drift

Configuration drift occurs when devices gradually deviate from approved standards.

Common causes include:

• Emergency troubleshooting changes
• Temporary fixes
• Unauthorized modifications
• Incomplete rollback procedures
• Documentation gaps

Over time, configuration drift can introduce:

• Security risks
• Performance inconsistencies
• Compliance issues
• Operational instability

Automated configuration management helps maintain consistency across the network.

Why Configuration Backups Matter in 2026

Several industry trends have increased the importance of automated backups:

Industry Trend	Impact
Network Automation	Requires reliable source-of-truth data
Hybrid Infrastructure	More devices to manage
Multi-Vendor Networks	Increased complexity
Compliance Requirements	Stronger audit expectations
NetDevOps Adoption	Greater emphasis on version control
Cybersecurity Risks	Need for rapid recovery capabilities

As a result, automated configuration backups are now considered a foundational operational practice.

How Oxidized Works

Understanding the Oxidized workflow helps engineers design more effective deployments and troubleshoot issues when they arise.

At a high level, Oxidized follows a simple but highly scalable process.

Step 1: Device Inventory Collection

Oxidized begins by obtaining a list of managed devices.

Device information can come from multiple sources:

• CSV files
• SQLite databases
• SQL databases
• LibreNMS
• HTTP APIs
• Custom inventory systems

Each record typically contains:

• Hostname
• IP address
• Device model
• Group information

Example inventory entry:

core-sw01.example.com:cisco
edge-rtr01.example.com:cisco
fw-dc01.example.com:fortios

Step 2: Secure Device Connectivity

Oxidized establishes management sessions using:

• SSH
• Telnet (legacy environments)

SSH should always be preferred because it provides:

• Encryption
• Authentication
• Integrity protection

Step 3: Configuration Collection

The platform executes vendor-specific commands to retrieve running configurations.

Examples include:

Cisco IOS:

show running-config

Juniper Junos:

show configuration

Arista EOS:

show running-config

The appropriate command is determined automatically by the configured device model.

Step 4: Output Normalization

Network devices often include dynamic information such as:

• Timestamps
• Counters
• Runtime values

Oxidized can remove these elements to prevent unnecessary configuration changes from appearing in version control.

This significantly reduces false-positive alerts.

Step 5: Configuration Storage

Collected configurations are stored using configurable output backends.

Common options include:

• Git repositories
• Flat-file storage
• Remote repositories

Git remains the most popular choice due to its version-control capabilities.

Step 6: Change Tracking

Whenever a configuration changes:

• A new commit is generated
• Previous versions remain available
• Differences can be reviewed

This creates a complete audit trail.

Typical Backup Workflow

Stage	Action
Inventory	Device list imported
Connection	SSH session established
Collection	Configuration retrieved
Processing	Output normalized
Storage	Configuration saved
Versioning	Git commit created
Review	Engineers compare changes

This workflow enables continuous configuration visibility across the network.

oxidized

This generates the default configuration directory:

~/.config/oxidized/

Step 6: Review Generated Files

Common files include:

~/.config/oxidized/config
~/.config/oxidized/router.db

These files form the foundation of the Oxidized deployment and will be customized in the next section.

In Part 2, we will configure Oxidized for production use, deploy it with Docker, onboard network devices, integrate Git version control, enable the web interface, automate backups, and build a scalable multi-vendor configuration management platform.

Installing Oxidized with Docker

Containerization has become the preferred deployment method for many organizations because it simplifies upgrades, improves portability, and reduces dependency management challenges. Running Oxidized in Docker provides a consistent deployment model across development, testing, and production environments.

For organizations already using container platforms, Docker-based deployments often integrate naturally into existing operational workflows.

Why Use Docker for Oxidized?

Docker deployments offer several advantages:

Benefit	Description
Simplified Deployment	Eliminates manual dependency installation
Portability	Run consistently across environments
Easier Upgrades	Replace containers without rebuilding servers
Isolation	Reduces impact on host operating system
Scalability	Supports orchestration platforms
Disaster Recovery	Faster restoration of backup systems

Deploying Oxidized Using Docker

Create a dedicated directory for the deployment:

mkdir oxidized
cd oxidized

Create a Docker Compose file:

version: '3'

services:
  oxidized:
    image: oxidized/oxidized:latest
    container_name: oxidized
    restart: unless-stopped
    ports:
      - "8888:8888"
    volumes:
      - ./config:/home/oxidized/.config/oxidized
      - ./git-repos:/home/oxidized/.config/oxidized/repos

Start the container:

docker compose up -d

Verify the container status:

docker ps

A successful deployment should show the Oxidized container running and listening on the configured web interface port.

Production Docker Recommendations

For enterprise deployments:

• Use persistent volumes
• Store Git repositories on reliable storage
• Implement regular backups of the Oxidized configuration
• Monitor container health
• Integrate logs into centralized logging platforms
• Use image version pinning rather than latest tags

Creating the Oxidized Configuration File

The configuration file controls how Oxidized connects to devices, retrieves configurations, and stores backups.

Understanding the Configuration Structure

The primary configuration file is typically located at:

~/.config/oxidized/config

The file defines:

• Authentication settings
• Inventory sources
• Backup storage locations
• Logging preferences
• Polling intervals
• Web interface options

Example Production Configuration

---
username: oxidized
password: SecurePassword

model: cisco

interval: 3600

use_syslog: false

threads: 30

timeout: 20

rest: 0.0.0.0:8888

input:
  default: ssh
  debug: false

output:
  default: git
  git:
    user: Oxidized
    email: oxidized@example.com

source:
  default: csv
  csv:
    file: ~/.config/oxidized/router.db
    delimiter: !
    map:
      name: 0
      model: 1

This configuration establishes a foundation suitable for many production environments.

Important Configuration Parameters

Parameter	Purpose
username	Device login account
password	Device authentication password
interval	Backup frequency
threads	Concurrent device processing
timeout	Session timeout
rest	Web interface listener
source	Inventory source
output	Backup destination
input	Connection protocol

Selecting appropriate values depends on environment size and operational requirements.

Adding Network Devices

Before Oxidized can collect configurations, devices must be added to the inventory source.

Using a CSV Inventory

The simplest method uses a CSV-based inventory file.

Example:

core-sw01:cisco
edge-rtr01:cisco
dist-sw01:nxos
fw-dc01:fortios

Each entry typically includes:

• Hostname or IP address
• Device model

Additional fields can be added depending on requirements.

Multi-Vendor Inventory Example

Modern enterprises rarely operate a single-vendor network.

Example inventory:

core-rtr01:cisco
core-rtr02:cisco
agg-sw01:nxos
agg-sw02:nxos
edge-fw01:fortios
edge-fw02:fortios
dc-leaf01:eos
dc-leaf02:eos
branch-rtr01:junos
branch-rtr02:junos

This allows Oxidized to execute vendor-specific commands automatically.

Device Onboarding Workflow

A typical onboarding process follows these steps:

1. Verify SSH connectivity.
2. Confirm authentication credentials.
3. Identify device model.
4. Add device to inventory.
5. Test configuration retrieval.
6. Verify backup storage.
7. Review Git commits.

Following a standardized onboarding process reduces deployment errors.

Configuring Git Integration

One of the most powerful features of Oxidized is its ability to integrate directly with Git.

Git transforms configuration backups into a fully version-controlled system.

Why Git Matters

Traditional backup systems store snapshots.

Git stores history.

This distinction is critical because network engineers often need to answer questions such as:

• What changed?
• When did it change?
• Which device was modified?
• Can we restore a previous version?

Git provides all these capabilities.

Benefits of Git-Based Configuration Management

Capability	Operational Value
Version Control	Historical tracking
Rollback	Faster recovery
Auditing	Change accountability
Collaboration	Team visibility
Compliance	Change evidence
Integration	CI/CD compatibility

Configuring Git Output

Update the configuration file:

output:
  default: git
  git:
    user: Oxidized
    email: oxidized@example.com

Initialize the repository:

mkdir repos
cd repos
git init

Restart Oxidized:

systemctl restart oxidized

New backups should now appear as commits within the repository.

Understanding Git Commits

Each time a configuration changes:

1. Oxidized retrieves the new configuration.
2. Git compares the new version.
3. A commit is created automatically.
4. Historical versions remain accessible.

This process creates a complete audit trail.

Example Change Tracking Workflow

Step	Action
Initial Backup	Configuration stored
Device Change	Configuration modified
Polling Cycle	Oxidized detects change
Git Commit	New version created
Audit Review	Engineer reviews differences

This workflow is one of the primary reasons organizations adopt Oxidized.

Enabling the Web Interface

The Oxidized web interface provides visibility into collected configurations and historical changes.

Benefits of the Web Interface

The web interface allows engineers to:

• View device backups
• Review change history
• Compare configurations
• Verify backup status
• Troubleshoot collection issues

Configure REST Service

Add the following setting:

rest: 0.0.0.0:8888

Restart the service:

systemctl restart oxidized

Access the interface:

http://server-ip:8888

Security Considerations

The web interface should never be exposed directly to the internet.

Recommended controls include:

Security Control	Purpose
Reverse Proxy	Centralized access
HTTPS	Encryption
VPN Access	Restricted connectivity
Firewall Rules	Limit exposure
Authentication Layer	User validation

These controls improve overall security posture.

Scheduling and Automation

Automation is one of Oxidized’s primary strengths.

Instead of manually collecting backups, engineers can define automated schedules.

Understanding Polling Intervals

The interval parameter controls how frequently devices are checked.

Example:

interval: 3600

This instructs Oxidized to check devices every hour.

Recommended Polling Frequencies

Environment Type	Suggested Interval
Lab Networks	6–24 Hours
Small Business	4–12 Hours
Enterprise Campus	1–4 Hours
Data Center	30–60 Minutes
Critical Infrastructure	15–30 Minutes

Selecting the right interval depends on change frequency and operational requirements.

Backup Automation Best Practices

1. Use scheduled polling.
2. Enable Git version control.
3. Monitor backup failures.
4. Verify backup integrity regularly.
5. Test restoration procedures.
6. Review change history frequently.
7. Store repositories securely.

Automation only provides value when backups are consistently verified.

Multi-Vendor Backup Examples

One of Oxidized’s greatest strengths is its ability to manage heterogeneous environments.

This broad compatibility allows organizations to standardize configuration management across the entire network infrastructure regardless of vendor selection.

The next section will focus on LibreNMS integration, configuration drift detection, security hardening, troubleshooting common issues, Oxidized versus RANCID comparisons, enterprise scalability strategies, and configuration backup best practices for large-scale production deployments.

Oxidized with LibreNMS Integration

One of the most powerful deployment models combines Oxidized with LibreNMS. While LibreNMS provides network monitoring, alerting, and device discovery, Oxidized focuses on configuration backup and version control. Together, they create a highly efficient network operations platform.

Why Integrate Oxidized with LibreNMS?

Without integration, network engineers often maintain separate device inventories for monitoring and configuration management. This duplication increases administrative overhead and creates opportunities for inconsistencies.

By integrating LibreNMS and Oxidized, organizations gain:

Benefit	Description
Centralized Device Inventory	Devices discovered by LibreNMS become available to Oxidized
Reduced Administration	No duplicate inventory management
Improved Accuracy	Consistent device records
Faster Onboarding	New devices can be backed up automatically
Better Operational Visibility	Monitoring and configuration management work together

Integration Workflow

A typical LibreNMS and Oxidized integration process follows these steps:

1. LibreNMS discovers network devices.
2. Device information is stored in the LibreNMS database.
3. Oxidized retrieves inventory information from LibreNMS.
4. Oxidized connects to devices via SSH.
5. Configurations are collected automatically.
6. Backups are stored in Git.
7. Configuration history becomes accessible through both platforms.

Example LibreNMS Source Configuration

source:
  default: http
  http:
    url: http://librenms.example.com/api/v0/oxidized
    map:
      name: hostname
      model: os

The exact configuration may vary depending on the LibreNMS deployment and API configuration.

Benefits for Enterprise Operations

Organizations managing hundreds or thousands of devices often find that LibreNMS integration significantly reduces operational overhead while improving backup coverage and inventory accuracy.

Configuration Drift Detection

Configuration drift is one of the most common operational challenges in enterprise networks.

What Is Configuration Drift?

Configuration drift occurs when devices gradually deviate from approved standards or intended configurations.

Drift can result from:

• Emergency troubleshooting changes
• Temporary workarounds
• Unauthorized modifications
• Manual configuration updates
• Incomplete rollback procedures
• Poor change documentation

Over time, configuration drift creates inconsistencies across the network.

Risks Associated with Configuration Drift

Risk Area	Potential Impact
Security	Unauthorized access or weakened controls
Compliance	Regulatory violations
Operations	Inconsistent behavior
Troubleshooting	Increased complexity
Automation	Unpredictable outcomes
Disaster Recovery	Difficult restoration processes

How Oxidized Helps Detect Drift

Every time Oxidized retrieves a configuration, it compares the current version against historical records.

When differences are identified:

• New Git commits are generated
• Previous versions remain available
• Engineers can review changes immediately

This continuous visibility helps teams identify drift before it becomes a significant operational issue.

Example Drift Detection Workflow

1. Baseline configuration is backed up.
2. An engineer makes a configuration change.
3. Oxidized performs its next polling cycle.
4. The modified configuration is detected.
5. Git records the change.
6. Engineers review the differences.
7. Changes are validated or corrected.

This process creates an effective mechanism for maintaining configuration consistency.

Security Best Practices

Because Oxidized stores sensitive network configurations, security should be a primary design consideration.

Use Dedicated Service Accounts

Create dedicated accounts specifically for Oxidized.

Avoid using:

• Personal administrator accounts
• Shared credentials
• Root-level access

Instead, implement role-based access control whenever possible.

Implement SSH Key Authentication

SSH keys provide stronger security than passwords.

Benefits include:

• Reduced credential exposure
• Improved automation
• Better auditability
• Stronger authentication

Example key generation:

ssh-keygen -t rsa -b 4096

Deploy public keys to managed devices whenever supported.

Restrict Management Access

Limit Oxidized communication to management networks.

Recommended controls include:

Control	Purpose
Management VLANs	Isolate management traffic
ACLs	Restrict access paths
Firewalls	Limit connectivity
VPN Access	Secure remote administration
Network Segmentation	Reduce attack surface

Secure Git Repositories

Git repositories contain valuable information about the network.

Protect repositories through:

• Access controls
• Multi-factor authentication
• Encryption
• Backup policies
• Audit logging
