Comprehensive Guide to Data Backup Solutions and Architectures

In the past I wrote a comprehensive series on data backup, covering everything from basics to advanced topics, and now I have compiled and updated the articles for easy reference.

1. Getting Started – An introductory article for newcomers to data backup, offering a clear yet thorough overview of backup concepts and practices.

2. Backup Software Architecture – Overview of various backup products such as Veeam, NetVault, eBackup, and generic solutions like Veritas NBU, Simpana, Data Protector, etc., describing their basic architecture.

3. Distributed Index Technology – Introduction to CV distributed (secondary) index technology used for managing large backup indexes.

4. Key Features – Discussion of essential backup features such as snapshots, replication, and deduplication.

5. Reliability and Availability – Examination of how the reliability and availability of backup software affect overall data reliability.

6. Virtualization Support – Description of backup support for major virtualization platforms (VMware, Hyper‑V, FusionSphere, Citrix) and specialized solutions like Veeam, eBackup, Avamar, NetVault vRanger.

7. Deduplication in Backup – Explanation of multi‑copy backup strategies and how deduplication optimizes storage.

8. Storage Capacity and Performance Planning – Guidance on calculating backup storage capacity and performance, including IOPS vs bandwidth considerations.
