====== 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.
    * **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 Objectives =====
{{:rpo_rto.png?nolink|}}
  * **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 =====
  * **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.

====== 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. <WRAP center round important 60%>
As the saying goes: “you don’t have backups until you restore them.”
</WRAP>


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.
