>> Is cloud disaster recovery a good choice for DR storage?

In this podcast, we interviewed Pierre Dorion, senior consultant with Long View Systems Inc., about the basics of disaster recovery storage, particularly whether it’s better to outsource disaster recovery, or keep it in-house. In this podcast, you will learn about data storage best practices for disaster recovery, whether or not tape backup is still a good choice for your organization, and about the pros and cons of cloud disaster recovery.

>> Remote data replication FAQ
Some organizations with more than one location choose remote data replication for disaster recovery. There are a lot of factors to consider when deciding if this approach is right for your needs. David Chapa, senior analyst with the Enterprise Strategy Group, outlines the pros and cons, what you need in place to facilitate this approach, how virtualization fits in, and the major vendors in this space.

>> Data security issues and DR planning
Kevin Beaver, independent information security consultant at Principle Logic LLC, takes a closer look at disaster recovery security in this Q&A. Find out the most important steps to take in order to best protect yourself against security vulnerabilities, what technologies are best suited for disaster recovery security and how to perform tests to see if your environment is secure.

>> Colocation data centers: The pros and cons
Colocation data centers are an alternative to setting up your own disaster recovery site in a remote location or outsourcing your disaster recovery to to a disaster recovery service. Colocation facilities offer a data center in which organizations can set up their own network, servers and storage. Although there are several benefits of using colocation centers for DR, users should make sure their colocation data center is secure and in the right location. In this Q&A, Harvey Betan, an independent business continuity planning consultant, describes the benefits of a "colo data center" for DR, what criteria you should follow when choosing a colocation facility and what you can expect to pay for a colocation facility.

>> Disaster recovery monitoring tools boost data protection and simplify DR
Disaster recovery monitoring tools are put in place to help monitor changes that occur in data storage environments, and can notify users of these changes before a disaster occurs. Because they monitor changes, DR monitoring tools can often boost data protection and simplify disaster recovery processes. Jon Toigo, CEO and Managing Principal of Toigo Partners International, discusses DR monitoring tools and how they work in this Q&A.

>> Factoring VoIP into your disaster recovery plan
Voice over IP (VoIP) has been adopted by many organizations for its operational benefits, but what do you need to consider about VoIP from a disaster recovery (DR) standpoint?

Which one is better for disaster recovery? If you are backing up your data to tape and disk, are there other issues to keep in mind? W. Curtis Preston, independent backup expert and executive editor, discusses source and target deduplication, how these approaches differ, what that means from a disaster recovery perspective and more in this Q&A.

>> Hosted PBX systems offer cost-effective telephone disaster recovery with caveats
Hosted private branch exchange (PBX) systems can be attractive for companies looking to cut back on voice communications costs. However, hosted PBX systems are not a good fit for everyone. Paul Kirvan, an independent disaster recovery (DR) and business continuity (BC) consultant, outlines what you should consider before adopting a hosted PBX system in this Q&A.

>> WAN optimization continues to evolve; integration with data deduplication products on the horizon
The adoption of cloud storage and virtualization are driving wide-area network (WAN) optimization implementation and it is becoming clear that WAN optimization is more flexible than we've thought about it in the past. Jeff Boles, senior analyst with The Taneja Group, discusses WAN optimization in this Q&A.

>> WAN clustering emerges to provide transparent failover between physical sites
