DR & Backup


DR & Backup

Backup software is evolving in a number of different ways. In the past, it only had to do one thing -- make a copy of data that can be restored in the event of a storage or server failure. And while that is still its primary function, today's backup software platforms can do much more. For example, many organizations cannot tolerate long periods of downtime while data is being restored. To deal with that issue, backup software vendors are adding features that are aimed at reducing recovery time and point objectives.

We first look at two of these technologies -- snapshot and recovery-in-place. Backup and archive have traditionally been considered separate disciplines, but today that is changing. Many backup software products have added archiving functionality such as search and indexing, which allows users to create archives using their backup software instead of purchasing and managing a separate product. Next, we study archiving; how it is converging with backup, and how it helps ease backup issues. To conclude the series, we look at another area of backup convergence: disaster recovery (DR). Backup has always been a part of DR, but today, backup software products are offering specific functionality such as replication and cloud storage connectivity that can make DR easier to manage.

Disaster recovery (DR) is an area of security planning that aims to protect an organization from the effects of significant negative events.

A disaster can be anything that puts an organization's operations at risk, from a cyber-attack to equipment failures to natural disasters. The goal with DR is for a business to continue operating as close to normal as possible. The disaster recovery process includes planning and testing and may involve a separate physical site for restoring operations.
