Protecting NAS Devices from Data Loss

NAS (Network Attached Storage) as a storage option is unbeatable. It’s cost-effective, functional and flexible. However, as with all storage devices, data loss cannot be completely ruled out.  Each NAS device data loss has its own history, but there are frequently occurring scenarios that require a restoration of network storage. Human error: Human error is a common cause when NAS/ RAID (redundant array of independent disks) data is lost. Data …Read More

Recovery of a NAS Server is a Highly Complex Endeavor

So, you think recovering a NAS server is an easy task?  Well, think again.  NAS servers may be a lower-cost RAID based solution aimed at small to medium sized companies, but technically, they are as complex and difficult to recover from as some of the high-end storage systems.  Since most NAS systems manufactured today have advanced features similar to those of high-end SANs, like deduplication, virtualization support, and iSCSI targeting, …Read More

6 Tips to Prevent Data Loss in Your RAID Based Storage Array

Since the introduction of the concept of RAID, it has redefined how storage systems manage and store data. The basic concept of this technology is actually quite simple: A RAID array is a configuration of many different physical hard disks that together create the used RAID architecture (RAID level 0, 1, 5 etc.).  The RAID architecture then distributes data over all disks because the RAID is regarded as one single …Read More

Make it big! Recovery solutions for large storage systems (Part2)

In the first part of this article we covered the storage systems architectures, now we want do give some insights on how to cope with system failures and data loss: Avoiding storage system failures Though you may not be able to prevent a disaster from happening, you may be able to minimize your downtime. There are many ways to reduce or eliminate the impact of storage system failures. For example, you …Read More

Make it big! Recovery solutions for large storage systems (Part 1)

Storage systems have become their own unique and complex area of IT and the term “storage systems” can mean different things to different people. So how do we define these systems? In this article, Storage systems are the hardware that store data. For example, this may be a small business server supporting an office of ten users or less – the storage system would be the hard drives that are …Read More

How does RAID storage work? – Part 2

In part 1 of this article, we explained the basic idea of RAID, as well as the most commonly used terms when talking about this type of storage. In this second part, we’ll take a look at what RAID levels are and explore how some of the traditional level configurations work. We’ll also find out what challenges RAID storage can bring if data recovery services are required. Let’s take a …Read More

How does RAID storage work? Part 1

Redundant Array of Independent (originally Inexpensive) Disks (RAID) is a term used for computer data storage systems that spread and/or replicate data across multiple drives. RAID technology has revolutionized enterprise data storage and was designed with two key goals:  increase data reliability and increase I/O (input/output) performance. Unfortunately though, RAID storage isn’t a perfect technology and as a result data loss can still occur when using these systems. In this …Read More

Large Scale Solutions in Storage Systems

Storage systems have become their own unique and complex computer field and can mean different things to different people. So what is the definition of these systems? Storage systems are the hardware that store data. For example, this may be a small business server supporting an office of ten users or less—the storage system would be the hard drives that are inside of that server where user information is located. …Read More
