• The Wrong And Right Technique To Recover RAID Arrays While Minimizing Loss


    Have a RAID server problem and need to recover that RAID system as quickly as possible? When looking for RAID data recovery, the choices are very simple. You can choose to go the smart, correct way, and you can choose the hassle and high expense of going in the wrong direction. The correct way seems like it would be the easy, clear choice, as it slashes general downtime and cuts expense. Still, many administrators choose the worst way when they need to recover raid systems, and it costs not only money, but data. This article may help you decide.

    How Important Is That Data?

    If you've had a case where you need to rebuild a RAID server (which often means more than a single hard drive in the array has broken down), remember that the number one assessment you have to make is one of data importance. Are you using the performance advantages of a RAID 0 to speed up your Halo games? If there isn't anything seriously important to your life, consider rebuilding the array by yourself. Professional restoration of a RAID array may get costly, as not all hard drive recovery shops actually do it. So if the files you may have lost isn't that key, purchase some hard drives and do your own rebuild.

    The other example case is that the broken down RAID you're using is running an Oracle database used by your company's sales people thousands of times per day. Or running a CRM system that is important when communicating with your customers. Situations similar to these are perfect for professional RAID recovery professionals because you simply shouldn't risk a "we'll see what happens" solution. If your company's very business operations are at risk because of a failed system, do not bother attempting to repair the server yourself. It is time to call in a professional.

    Timing Is Everything

    Each moment may seem like a century when a business-critical RAID server has gone kaput. And in fact, when you multiply the number of stationary workers by those minutes, it may actually be hours. It's never that difficult to find a data recovery shop on the internet, of course, but if your recovery is ultra-important, consider doing a search for "immediate RAID data recovery" or "overnight raid recovery". The industry does have a classic term for express-type delivery, which is often known as "expedited". However, only a handful of shops actually offer emergency repair services that can have your repaired server back in your hands within a single day or less. While the expense of these "ultra-expedited" deliveries are somewhat more expensive, it may be worth it if your lost server is killing productivity for the company as a whole.

    A List Of Do Not's For RAID Recovery

    In an emergency server breakdown situation, many IT administrators will do the best to repair or recover systems without help, which sometimes can help, and in others actually damage the process. Here are a few examples:

    Moving A RAID Drive Within The System - Whether you've had a total multiple hard drive crash, or if only a single drive has failed in your array, please remember to not try to move the drive in any way. Keeping your array as is is important to restoring any lost data, and if you mess with drive order, you are the prime suspect in the data loss.

    Are Your Connections Live? - Yes, it is a simple situation, one that even the most basic support technician will mention, but it is a necessary one. Snug cable connections throughout the system setup are necessary for correct function, and if one cable comes detached, a drive can "appear" to have been lost. Don't make the mistake of shipping out a server for a repair when it's actually is working!

    CHKDSK, The Enemy Within - Yes, Windows has an easy disk checker known as CHKDSK that is there to help you find errors. Issue here is that CHKDSK was NOT created for RAID servers or complex hard drive setups. Save yourself some hassle and bad overwrites by avoiding it altogether!

    Whatever your difficulty, if you're using a pricey, professional platform, you will need professional services when an emergency arrives. When you need to recover raid systems, don't try to penny-pinch!
