    RAID Recovery

    When you get to RAID levels 4 and 5, you are dealing with extremely sophisticated arrays that employ a number of techniques to increase read/write performance and redundancy in order to protect mission critical data. Let's take a look at these RAID levels, which offer performance benefits over RAID 2 and RAID 3 arrays, and redundancy benefits over a RAID 1 array.

    Level 4 RAID Arrays

    Level 4 RAID is one of the more sophisticated of the original 5 RAID levels originally devised by technology experts at Berkeley. Level 5 RAID, though, with distributed parity, has it beat in terms of write performance and data redundancy.

    Virtual Recovery

    Virtualization -- the creation of virtual servers to maximize data storage and improve efficiency -- has many benefits. But there are certain vulnerabilities inherent in a virtual operating system. Understanding these vulnerabilities, and following best practices when a virtual server is established, can minimize the chances that you'll need emergency data recovery services.

    Here are five ways to take good care of your virtual servers so that they will take good care of you.

    1 - Practice “good housekeeping” with your virtual servers.

    When your IT staff practices proper maintenance and care with virtual servers, this minimizes the chances of a failure requiring professional data recovery services.

    One example of good housekeeping is avoiding “server sprawl.” Every virtual server that has been created should have a specific purpose, reason for being, and a clear record of its creation.

    Data Loss

     a commercial making the rounds right now, where a groom is getting ready for his wedding and, rather than offering him the typical well wishes, people tell him, “You're going to lose it all today.” He hears this from his father, his best man, and even the limo driver.

    You begin to wonder what they mean as the look of trepidation on the groom's face begins to grow. The tagline bears the message that data loss occurs without warning; you never know when or where it may happen.

    This is absolutely true but, like other disasters, including natural disasters like hurricanes, floods or fires, there are ways you can be prepared for data loss caused by hard drive failure or other events.

    You can't tell exactly when data loss may occur, but here are three ways to make sure you're not caught completely blindsided when it does happen -- and can possibly prevent the complete loss of your mission critical data, whether it's important operating and financial files for your business or simply your family photos (including those wedding pictures!)

    RAID Recovery

    When RAID arrays were first proposed by the minds at Berkeley in the 1980s, there were five levels of RAID array. Today, researchers and manufacturers have devised other variations of RAID levels, but the original five are considered, by purists, “true” levels of RAID.

    Of course, there's also RAID “0,” which many experts don't consider to be a RAID array but it's worth discussing in this context. Read on to find out more about the five levels of RAID, plus one level that really isn't.

    RAID 0 - RAID stands for Redundant Array of Independent (or Inexpensive) Drives. Therefore, RAID 0, which contains no redundancy, isn't really a RAID level. RAID 0 stripes data across two or more drives, providing the best storage efficiency and fast performance, but no protection against data loss.

    Virtual recovery

    As VMware grows in popularity, so do replication processes and applications. Like a RAID server that relies on redundancy, replicating the data on your virtual machine is one form of on-site back-up. The ease with which you can replicate data from one virtual machine to another, creating an easy-to-access back-up, makes virtual machines more secure and less susceptible to the need for emergency data recovery. 

    However, to get the most out of your virtual server, you'll want to follow virtual machine replication best practices.

    1- Make sure a dedicated network connects your production and disaster recovery site so that you can access your data in the event of virtual machine failure and data recovery emergency. 

    2 - Make sure replication is completed frequently, so you'll always have up to date back-ups available in the event of an emergency. VmWare vSphere's new vStorage APIs for Data Protection offer nearly continuous data protection (CDP).

    Flash Recovery

    Storage media leaders Toshiba and Sandisk, operating under the funding of a joint venture called Flash Forward, have announced the opening of a new factory in Mie Prefecture, Japan, devoted to the manufacture of NAND flash memory. Fab 5 is located at Toshiba's Yokkaichi Operations and is the third 300mm wafer NAND fabrication facility under the corporate umbrella.

    Meanwhile, hard disk drive, flash memory, laptop, and smartphone (among other things) manufacturer Samsung announced plans to build a new, $4 billion flash memory plant in China to support the growth of the industry, as well.

    As the prevalence of flash memory grows, fueled by the popularity of smartphones, tablets and other mobile devices, these factories will help industry leaders keep pace with developments and production. 

    24 Hour Data Keeps Up with Flash, Too

    At 24 Hour Data, our data recovery specialists are working 24/7 to stay up to date on developments in flash memory and the latest data recovery methods to recover lost data from these sensitive chips.

    RAID Recovery

    As the costs of RAID drives drop even lower and storage capacities for hard disk drives exceed 1 TB, more and more small businesses and home users are incorporating RAID arrays into their data storage methods. RAID arrays can be used as home media servers, to expand storage capabilities across a home or a small business network, and to boost performance while enhancing the security of data stored on the server.

    The top choice for many home and professional users is a RAID 5 array, which typically employs a controller for even better performance.

    While most RAID levels provide either greater storage capacity, or enhanced security and better performance, a RAID 5 array offers greater storage capacity with storage striped across four or more disk drives, along with decent speed and data protection. 

    RAID 5 is not as secure as RAID 1, which employs mirroring for redundancy, or as fast as RAID 0, but it offers enough of each that it is one of the most popular levels of RAID.
