Backup software: Snapshot management, archiving and DR

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.

In this e-book, 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.

  • How backup is evolving to meet restore demands

    Recovery is all about having good backups; without a clean, consistent backup, there is nothing to recover. And today, recovery speed is also very important. Many organizations cannot tolerate long periods of downtime while data is being restored. So, data protection vendors are adding features that are aimed at reducing recovery time (RTO) and point objectives (RPO).

    Snapshot is one of the storage tools fueling a shift in how enterprises protect data. This is not a new technology, but advancements in backup software have made them more practical. Snapshots allow for quick restores of data, and many backup software vendors have integrated with storage arrays, so snapshots can be managed as part of the backup process. When used together with replication, snapshots can protect against primary storage failures. Another technology gaining steam in today's market? Recovery-in-place. This technology, which is enabled by server virtualization, allows users to run an application from a backup instance of a virtual machine while the primary VM is being restored. In some cases, this can be used in place of replication. In this e-book chapter, you'll learn how these technologies work -- as well as their pros and cons. You will also benefit from expert insight into what using these technologies can do for your business.
