You may have noticed countless testimonials all across the internet from people claiming to have lost important data. They aren't novices who just know the basics of operating a computer and surfing the net. These are computer-savvy individuals who themselves never thought it to be possible that one day they would face data loss. But, just like these people were afflicted by the dreaded curse of data loss, so could you. The thing is that none of us believe that we could ever be the victims of this technical accident until and unless it happens to us. However, there's no need to fret in these times of modernized technology and advanced systems. Multiple options are available, which can help backup your data, so that those vital documents or large media files aren't lost forever. The importance of our digital data has scaled such unprecedented heights that we can no longer rely solely on technology to bail us out of tricky situations amounting to loss of data. We need to curb our own negligence and laziness. We have to stop taking technology and the safety of our digital files for granted. So, just how do we go about creating conceivable and secured option to backup our data? The problem is that they are too many digital backup plans doing the rounds these days, which confuses us as to which could be the best option. Moreover, most of these backup plans are viable enough to implement, since they don't offer feasibly solutions based upon your situation. Many of these solutions come across as complex, disorganized, and difficult to sustain for a lengthy period. This is where the backup option known as RAID comes in. It might mistake this name for a bug spray product available on the internet, but rest assured, RAID is one of the best digital backup options currently being circulated. RAID: RAID (Redundant Array of Independent Disks) is a series of methods for dispensing your digital files via numerous hard-discs, so that they always remain protected and, at times, their performance may also be enhanced. There are various kinds of RAID arrays. Let's take a look at the most commonly used ones. RAID 0: This is the most elementary of RAID array. It dispenses data via two or more physical hard-discs. With the RAID 0, every file is written such that it can be accessed through diverse hard-disks. This enables sharing of bandwidth. It also improves the read/write duration for each additional hard-disk. Hence, the performance is vastly boosted with the help of the RAID 0. However, the drawback over here is that the entire backup system will crash, if a single hard-disk fails. RAID 1: This is the most widely-used form of RAID security. It utilizes two different hard-disks and copies all the data onto both the disks. This means that your computer employs two physical hard-disks to represent each virtual one, while maintaining the same data over both the physical disks. This is the safest form of RAID array, since your data remains intact in the event that one of your disks fail. RAID 1+0: This method takes the best features from the above two RAID arrays to deliver a single hybrid array with the best backup solution. RAID 1+0 is more commonly referred to as RAID 10. This technique requires a minimum of four hard-disks. It basically comprises of a RAID 0 array, where each branch of two separate hard-disks in a RAID 1 system. The most ideal method to adopt would be to implement either a RAID 1 or RAID 10 system for your local exterior backup. For this, you need to first purchase an exterior drive bay and stock it with two or four physical hard-disks, depending on which RAID array you employ. The RAID system ensures that your external digital backup plan consists of more than one physical hard-drive. This guarantees that your digital data is managed with redundant security, as opposed to a single drive, which is akin to failing just as easily as one of your internal hard-drives. We need to adopt the RAID method, because irrespective of how advanced technology becomes, it isn't technology's responsibility to maintain and protect our digital data. The responsibility lies solely on our shoulders.
