There's still a good two months until hurricane season officially begins on June 1 (it ends November 30), but it's never too early to begin thinking about your data recovery options if your mission critical data suffers damage or loss due to a flood or hurricane. Organizers of the National Hurricane Conference apparently agree, since they just held the 2012 National Hurricane Conference in Orlando, Florida, at the end of March. The event focuses on hurricane preparedness, response, recovery and mitigation to save lives and property in the continental U.S., and in the tropical islands of the Caribbean and the Pacific. Facts about Hurricanes and Data Recovery - The official Atlantic hurricane season spans from June 1 through November 30, when 97 % of all hurricanes occur,  but hurricanes have occurred outside of these months.   - The Pacific Southeast hurricane season stretches slightly longer, beginning officially on May 15.

VM Recovery Just as a conventional CPU has specific files that keep the machine running properly, there are files and collections of files on a virtual machine that do the same. The VMDK flat files store the content that is on the hard disk drives of a virtual machine. VMDK files (without the word “flat” preceding dot-vmdk) are the disk descriptor files, which contain all information regarding its associated flat file.  Meanwhile, VMDK Delta files, created during backups when a snapshot of a virtual machine hard drive is taken, store content from the time the snapshot was created until the time the snapshot is complete and operations return to normal. These files are then reconciled for an up-to-date snapshot, with all recent file changes reflected. These files also have corresponding disk descriptor files. Signs of VMDK File Corruption If any of these files on your virtual server or servers become corrupt, the machine may fail to power on. This may occur if: - a descriptor file is missing

Data Recovery Every year, Symantec, the makers of popular antivirus and security software for PCs, releases a Disaster Preparedness Survey. And, although the cost of lost data for small-to-mid-size businesses keeps going up, the study continues to show that businesses do not have the data protection they need.  According to the study, the median cost of downtime after a server crash, failure or other data recovery emergency is $12,500 per day. Even so, half of the survey respondents do not have a disaster preparedness plan in place. Even more startling, only 23 % of respondents report backing up their data daily; less than half back it up weekly or more frequently. That means about half of all SMBs don't back up their data at all.

VMware Recovery When a Virtual Machine File Server (VMFS), that is, one of the virtual servers within a machine, becomes corrupt, this can result in catastrophic data loss and the need for emergency vmware data recovery.  Knowing how to recognize the signs of VMFS corruption, and knowing how to handle the situation without doing further damage to your virtual environment, can mean the difference between preserving your data and being able to access your files or facing a data recovery emergency.  If one of your VMFS volumes becomes corrupt, it may be possible to migrate the files to one of the other, working, VMFS volumes. Caution: Do NOT power down your virtual machine before taking any other action. If you are facing a corrupt VMFS volume and you shut down the server, it may not be able to re-boot, leaving your mission critical files inaccessible.

RAID Data Recovery There are 10 standard RAID levels, 0 through 9. RAID levels describe the configuration of a RAID array, and relate to the patterns in which data is written to the RAID drive, the fault tolerance of the RAID array, and the space efficiency. To some degree, the RAID level can affect the number of drives in the array, but that doesn't mean that, for instance, RAID 9 uses nine hard drives. You can run any RAID level up to 9 with just two drives. Hybrid RAID Levels Beyond the standard RAID levels are Hybrid RAID levels, which means two different RAID levels are “nested” within one controller. (Rarely are more than two RAID levels nested.) Hybrid RAID array configurations include designations such as RAID 0+1, RAID 1+0, or RAID 5+0. Some people may eliminate the plus sign, resulting in RAID 10 or RAID 50, but that doesn't mean RAID “ten” or RAID “fifty.”

Server Recovery If your IT department has recently switched your company over to a  virtualization solution for your servers, it might be time to re-visit your choice of emergency data recovery service providers, too. You want to make sure that your data recovery service is well-versed in all forms of VMware and can recover your virtualized data as well as any data from a hard drive, RAID array or other storage medium. Here are some tips when it comes to choosing a new data recovery service for your virtualized server farm.

Virtual Recovery More than half of all companies today are using virtual servers to streamline their data storage and server use. However, virtual servers, as with any data storage method, are subject to fail for a variety of reasons, resulting in catastrophic data loss and the need for emergency data recovery. Let's look at five ways your virtual server may fail: 1. RAID failure - Remember, even a virtual server is based in real hardware, usually a RAID 5, RAID 6 or higher array. If two or more hard drives fail in a RAID 6 array, you could be looking at mission critical data loss. Additionally, a failed RAID drive, undetected, often leads to cascading failure of the entire array. And if the infrastructure on which your virtual server is built collapses, you'll need emergency data recovery.

Data Recovery Today's busy executives aren't always tied to their company's server. Often, rather than connecting to the network or NAS device, they work locally on their laptop. This is especially true during travel, when the security of WiFi networks may not be guaranteed. If you're a professional executive, business owner or CEO, your whole life may be stored on your laptop. Regular back-ups are critical. At CES 2012, Rebit, Inc. announced a new continuous, automatic back-up with built-in redundancy. The hybrid cloud back-up solution makes primary back-ups to a local NAS or USB drive, with redundancy backed up automatically to the cloud for access from anywhere with Internet capabilities. Cloud back-up protects data from: - Natural disasters like fires or floods, where a laptop, tablet or hard disk drive could be damaged beyond recognition, and even beyond the capabilities of the best data recovery service - Theft or loss, where there is no hard drive available to attempt data recovery  Data Recovery on the Road

RAID 6 Recovery RAID 6 is one of the newest RAID technologies to be employed, and is found on more and more servers and virtual servers from large companies like Microsoft. Experts predict that, within the next decade, RAID 6 will be the most popular RAID configuration available; it already offers the highest performance, the best fault tolerance, and the greatest stability of previous RAID levels. What's So Great About RAID 6? RAID 6 works in much the same way as RAID 5, with blocked data striping across any number of hard drives in the array, and distributed parity. However, parity is not only distributed across the disks in the array, it is also duplicated across the disks. This means that a RAID 6 array can suffer the failure of two hard drives and you'll still be able to recreate your RAID array from the existing drives. Erasure: Preventing Unrecoverable Read Errors
