Deployment Options
Veeam Backup & Replication can be deployed in various environments, including on-premises, private, public, and hybrid clouds. The prerequisites and functionality remain consistent across these environments.
Deployment Types
On-Premises Deployment - Scales from simple installations to complex infrastructures.
Service Provider Deployment - Used by providers offering Backup-as-a-Service (BaaS).
Cloud Workload Deployment - Protects workloads running on cloud VMs.
Simple Deployment
All components (server, proxy, repository) installed on a single machine.
Suitable for small-to-medium businesses (SMBs) needing local backup copies.
Can be deployed in public clouds like Azure, AWS, and others.
Backup data can be stored in disk-/file-based repositories or object storage.
Advanced Deployment
Business Considerations for Veeam Deployments
Understanding key business considerations ensures a successful Veeam Backup & Replication deployment. These principles help optimize backup strategies, security, and recovery objectives.
The 3-2-1-1-0 Rule
A best practice for data protection:
(3) Copies of Data - Maintain primary data and two backup copies.
(2) Different Media - Store backups on separate storage types (e.g., local disk + cloud).
(1) Offsite Copy - Ensure at least one backup is stored remotely.
(1) Offline/Air-Gapped Copy - Use immutable storage (e.g., Hardened Linux Repository, Object Lock).
(0) Errors - Automate testing and verification (SureBackup, SureReplica).
Key Backup Considerations
Backup Window - Schedule backups outside business hours to minimize impact.
Backup Type - Choose between incremental (efficient) or full (comprehensive) backups.
Storage Optimization - Enable compression and deduplication to reduce storage usage.
Data Encryption - Secure backups with encryption at rest and in transit.
Bandwidth Throttling - Limit network usage for WAN replication.
Repository Optimization - Match storage type to backup frequency (e.g., high-performance storage for frequent backups).
Backup Copy Jobs - Create offsite copies for disaster recovery.
Scale-out Backup Repository (SOBR) - Automate storage tiering and load balancing.
Retention Strategies
Short-Term Retention - Locally stored restore points for quick recovery.
Long-Term Retention - Weekly, monthly, yearly restore points (GFS policy).
Recovery Objectives
Recovery Point Objective (RPO) - Defines acceptable data loss period.
Recovery Time Objective (RTO) - Determines downtime tolerance.
Disaster Recovery Planning - Establish offsite backups, restore processes, and testing.
Security Considerations
Ransomware Readiness Checklist
Cyber resilience is critical in today's threat landscape. This checklist outlines key security measures to protect backup environments from ransomware attacks.
Secure Backup Components
Patch & Update Systems - Ensure all backup components are running the latest security updates.
Separate Backup Server from Production Domain - Prevent attackers from compromising backups via Active Directory.
Enable Multi-Factor Authentication (MFA) - Protect backup systems from credential theft.
Access & Permissions
Use Separate Admin & User Accounts - Limit administrative access to configuration tasks only.
Restrict Backup System Access - Ensure only authorized users can access repositories and databases.
Enforce Strong Password Policies - Require complex passwords (15+ characters, mixed case, numbers, symbols).
Backup Storage Security
Harden & Encrypt Backup Repositories - Use immutable storage to prevent unauthorized modifications.
Isolate Backup Storage - Ensure repositories are not directly accessible from production environments.
Follow the 3-2-1-1-0 Rule - Maintain multiple copies across different media and locations.
Encryption Best Practices
Secure Private Encryption Keys - Store keys in a protected environment to prevent unauthorized decryption.
Encrypt Backup Data - Prevent exfiltrated backups from being useful to attackers.
Encrypt Backup Network Traffic - Protect data in transit from interception.
Orchestrated Recovery
Identify Critical Applications - Define recovery priorities for business continuity.
Automate Disaster Recovery - Reduce manual errors and speed up recovery processes.
Regularly Test Recovery Plans - Validate backup integrity and ensure readiness for cyber incidents.

Zero-Trust Data Resilience
Zero Trust Data Resilience (ZTDR) extends Zero Trust principles to backup environments, ensuring data protection against cyber threats and unauthorized access.
Core Zero Trust Principles
Least-Privilege Access - Restrict access to only what is necessary, minimizing attack vectors.
Verify Explicitly - Authenticate and authorize every access request based on identity, location, and workload.
Assume Breach - Design security measures with the expectation that breaches will occur.
Key ZTDR Strategies
Separation of Backup Software and Storage - Prevent attackers from compromising both simultaneously.
Multiple Resilience Zones - Implement the 3-2-1 backup rule to ensure redundancy.
Immutable & Encrypted Backup Storage - Protect backups from unauthorized modifications or deletions.
Security Enhancements
Role-Based Access Control (RBAC) - Limit administrative privileges to essential personnel.
Network Segmentation - Isolate backup infrastructure from production environments.
Multi-Factor Authentication (MFA) - Strengthen access security for backup systems.
Automated Backup Verification - Use SureBackup and SureReplica to validate recoverability.
Scheduled Restores
A key pillar of Zero Trust resilience is regular restore testing — not just keeping backups, but actually restoring them into isolated environments to verify their integrity.
As the saying goes: “you don’t have backups until you restore them.”
In Zero Trust architectures, backups are often intentionally locked down and segregated, which improves security but can hinder accessibility. This makes routine, automated restore testing even more critical. By periodically spinning up test environments and validating backup data, teams can detect issues early and ensure recoverability under real-world conditions.
