BLOG: 5 best practices for effective data recovery

Ang Chye Hin | Aug. 26, 2011
Organisations need best practices to optimise the backup process, avoid data loss and corruption, minimise the impact on bandwidth and storage, and enforce business-relevant policy to recover data in case of disaster.

For a backup solution to have any real value, data recovery must be reliable. An ideal solution should eliminate loss of data and history associated with collapsing and re-mastering backup points.

Minimise impact on bandwidth and storage

Data de-duplication can increase backup efficiency and performance by eliminating redundant data blocks at the source and sending only changed blocks across the network. This enables IT organisations to achieve smaller data volumes, faster backups, lower bandwidth usage and optimal storage consumption.

Establish policy by business relevance

An ideal backup policy should ensure only business-relevant data assets are automatically preserved and protected against common disasters that cause severe data loss. A backup solution should enable granular policy that can flexibly address the hierarchical backup needs of individual business roles and regulatory mandates. Moreover, regulatory and legal compliance, Recovery Point Objectives (RPOs) and recovery responsiveness mandate the preservation and recovery of chronological data versions. An ideal solution should capture, catalogue, and retain a wide range of chronological recovery points and enable immediate time- or version-based recovery.

Streamline global enforcement of backup policy

A backup solution should enable administrators to enforce backup policies globally, whether in single or multiple geographically dispersed networks, without requiring manual deployment and administration at the endpoint locations. This is especially important as organisations go increasingly global.

Given the ever-increasing amount of data generated by today's businesses, IT can no longer avoid re-evaluating traditional backup methodologies that require the management of complex full/log/differential backups and the storage of massive amounts of duplicate data. The ideal solution should enable IT to apply best practices that optimise the backup process, avoid data loss and corruption, minimise the impact on bandwidth and storage, and globally enforce business-relevant policy.
