CDP is good enough to replace traditional backups

Posted by: Mkellett
continuous data protection, data backup,

Continuous data protection (CDP) has been gaining popularity in IT data storage environments for a while now. Both near-CDP and real-CDP systems continuously back up data and allow users to back up data to a significant point in time.

I recently sat down with W. Curtis Preston, an independent data backup expert and Executive Editor at TechTarget, to talk about CDP in more detail. He explained the differences between near-CDP and real-CDP, who should use CDP products in their enterprises and what CDP products are available today. But most importantly, Preston noted that CDP technology has evolved to be just as good as traditional backups, and expressed hope that continuous data protection would eventually replace traditional backup systems.

Will vStorage APIs for Data Protection take the place of VCB?

Posted by: Mkellett, server virtualization, vSphere, vStorage APIs

VMware’s latest release, vSphere 4, comes with a new feature, vStorage APIs for Data Protection. vStorage APIs for Data Protection was added to vSphere 4 to make all VMware backups more efficient by offering direct API-based integration for backups. However, many people currently use VMware Consolidated Backup (VCB) for their virtual server environments. So how is vStorage API for Data Protection different from VCB? Is it better? Will it eventually outrun VCB? And what are the pros and cons of vStorage APIs?

I sat down with Eric Siebert, an IT industry expert on virtualization and author of, to speak about this issue. His answers are available in the MP3 below.

The pros and cons of disaster recovery monitoring tools

Posted by: Mkellett
disaster recovery tools,

Disaster recovery monitoring tools are often used to monitor any major changes that have happened in a data storage environment. They also warn users of these changes to avoid any potential disasters because of them. But how do these DR monitoring tools work? Are there different types of tools you can use? If so, which ones are best for your environment? And what are the pros and cons associated with DR monitoring tools?

I sat down with Jon Toigo, CEO and Managing Principal of Toigo Partners International, to answer these questions. Listen to our conversation in the MP3 below, and as always, let us know your thoughts and experiences with disaster recovery monitoring tools.

disk-to-disk backup,, virtual tape library

Disk backup is popular for data backup and recovery. Companies can choose from a variety of strategies such as disk-to-disk (D2D), continuous data protection (CDP), and virtual tape libraries (VTLs). But what’s more popular for small- to medium-sized businesses (SMBs) to implement in their environment – VTLs or other types of disk backup? What are the pros and cons of each? And how does data deduplication differ between VTLs and other types of disk backup?

I sat down with Jeff Boles, senior analyst of Validation services at the Taneja Group to talk about VTLs vs. disk-to-disk backup in SMBs. Listen to the podcast below and let us know your thoughts too.

How continuous data protection can help with disaster recovery

Posted by: Mkellett
continuous data protection,

Continuous data protection (CDP) is a technology that’s implemented into data storage systems to capture changes made to data as they are made, making data backup and recovery processes easier for companies. But how can CDP help with disaster recovery efforts?

I sat down to talk with Kevin Beaver, an information security consultant, author, speaker and expert witness with Atlanta-based Principle, Logic about using CDP for DR purposes. Listen to the podcast below and let us know your thoughts on CDP for DR as well.

How virtualization can help in an SMB environment

Posted by: Mkellett
data migration,, storage virtualization

Data migration can be a frustrating data backup process for any storage environment, including small- to medium-sized businesses (SMBs). But storage virtualization can help ease the process of data migration for SMBs.

I sat down with Marc Staimer, president of Dragon Slayer Consulting, to talk about how virtualization can help an SMB environment. I asked him the following questions:

  • Is data migration a tedious process for SMBs? Why?
  • Can storage virtualization make data migration easier for SMBs? How?
  • What affordable storage virtualization products/vendors are available for SMBs?
  • What should users be wary of when deploying storage virtualization? For example, is it hard to back out of it if it’s not working?

Listen to the podcast below and let us know what your thoughts are on storage virtualization as well.
