Understanding key business considerations ensures a successful Veeam Backup & Replication deployment. These principles help optimize backup strategies, security, and recovery objectives.

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).

• 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.

• Short-Term Retention - Locally stored restore points for quick recovery.
  • Forever-forward incremental - Efficient but not compatible with SOBR move functionality.
  • Forward incremental - Includes periodic full backups for better chain management.
• Long-Term Retention - Weekly, monthly, yearly restore points (GFS policy).
  • GFS (Grandfather-Father-Son) - Assigns flags to full backups for archival.
  • Cloud Tiering - Moves older backups to object storage.

• 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.

• Physical Security - Restrict access to backup infrastructure.
• Infrastructure Hardening - Implement role-based access control (RBAC).
• Network Segmentation - Separate backup traffic from production networks.
• Immutability & Air-Gapped Storage - Protect against ransomware with offline backups.
• Backup Verification - Schedule SureBackup jobs to validate recoverability.

Cyber resilience is critical in today's threat landscape. This checklist outlines key security measures to protect backup environments from ransomware attacks.

• 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.

• 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).

• 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.

• 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.

• 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 (ZTDR) extends Zero Trust principles to backup environments, ensuring data protection against cyber threats and unauthorized access.

• 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.

• 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.

• 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.

A critical aspect of Zero Trust resilience is staged restores, where backups are tested in isolated environments before being reintroduced into production. This ensures data integrity and prevents reinfection from latent threats. Additionally, on-purpose destruction of test environments after validation reinforces security by eliminating potential attack surfaces. Engineers should automate these processes to maintain a clean and secure recovery workflow.
