If you are familiar with the technical ground, then you must have an idea of what disk mirroring is and how it’s useful. So, in other words, RAID 1 can be termed as the second copy of any data. But often, many people are concerned about a doubt, which is whether it serves as a backup.
However, RAID 1 has significance in many aspects. For example, systems that are under a lot of pressure for performance need heavy applications for transactions, need RAID 1.
However, if you are unaware of how RAID 1 works, then continue reading the rest of it below.
RAID 1: What is it, And How Does it Work?
To begin with, RAID also gets its name from Redundancy. A set of arrays that are independent in the disk and are redundant can form up into an ample space. This space is also known as an operational drive that is further called as RAID.
Now, you may wonder why it even exists. Well, when you are connected, the server is capable of connecting to many drives. This process of connection requires the server to impose read and write operations. Thus, it can increase the performance rate, whereas RAID can balance it out.
Now, RAID has many levels starting from 0 to 6 having different uses. However, only 0, 1, 5, and 6 are the most common levels of it. Based on these levels, a system’s performance is balanced out. This is because each level provides the server requirement for any application.
For example, if the server is looking into fast response speed on operations, RAID 0 is effective. Meanwhile, for reliability purposes, you can count on the RAID 1 level. And lastly, you get the best of both in RAID 5 level. However, there are notions that suggest RAID to be unlike any backup. Find out why.
RAID 1: Does it Work as an Alternative for Backup?
In case of data loss, you can refer to Data Recovery Dubai for assistance. Further, many already consider RAID to be a backup; there is a fine but distinctive change. From what we know, backup is the action of having copies of multiple data from the original one. So, when the original data sets become inaccessible, the copies can be retrieved. However, that is not the same as RAID. Here’s why
RAID 1 is Redundancy
As mentioned below, the set of arrays are also known for redundancy. In other words, Redundancy means that an action that will persistently continue, like a force, despite any problems. It can be related to both data or network and still have no hesitation in failure to keep running.
Unable to Stop Malware
There are many types of malware that are capable of structuring the system to the point of no return. One such malware is known as ransomware, which is capable of keeping your system under its control without you having access to it. These situations can be problematic because even high-end antiviruses fail to do anything. Now, RAID can minimize the destruction to a point, but it can not get rid of the source of infection. Meanwhile, any good back up can resolve the problem by eliminating any serious downtime.
RAID 1 Fails Recovery
As you know, RAID is an independent string of arrays that work in redundancy. Much to this knowledge, it can be easily concluded that required data is something that runs but is not copied somewhere. Hence, it can be helpful for any sustainable action, but when it comes to RAID 1 Data Recovery, it fails. This is one of the main reasons why the majority of people consider having their data backed up by different means so that for any accidental cause, they can rely on it more than RAID.
RAID Fails to Help during Disasters
Another similar reason why RAID is not considered as a backup is because of circumstantial proofs. Any natural calamity like a flood or hurricane can easily destroy data if the seriousness is grave. This implies that a company or any organization would consist of an ample amount of data, each worth a lot. That much amount of data is a lot in number, and RAID can often fail to mitigate it, which is why a secondary backup is also considered.
RAID can get Worse if Data is Corrupted
One of the biggest significance of RAID is its configuration. It is much capable of protecting data through its security layers and protocols. This implies that these configurations help minimize the probability of losing data. But, when it comes to data corruption, the same cannot be said. RAID is not helpful when a data or a set of data is corrupted. In fact, RAID makes it much worse. Since the data is corrupted, RAID can easily spread the overall damage. For such cases, the majority of companies switch to off-site backup plans.
As much as RAID is helpful in keeping your data secured with multiple security protocols, it has some limitations. For example, RAID can be useful up to a certain limit like system failure and other hardware issues that conflict with the data. But on the other hand, a backup solution is more likely effective. This is because a backup makes multiple copies of data, and these copies can be put anywhere like data centres or external hard drives. But, RAID can only be useful in times of any failure or system crash.
RAID 1 has many aspects that are useful to the system, but it does not pose as a backup option when it comes to RAID 1 Data Recovery. However, upon comparing it with other RAID levels, you can figure out how it differs and is beneficial in other forms. Keep updated on it for future references.
