This is a question that has been asked many times by users who are new to this term or do not clearly understand its benefits and whether they should use RAID or not on their dedicated servers.
Here I’ll try my best to answer this question and help you understand its importance as well. First we will try to understand:
What is RAID?
RAID stands for redundant array of independent disks where the data is mirrored to multiple disks for preserving data in case of disk failure.
In simple words, RAID is a backup system in which an additional hard drive is attached with the server which carries all the data on the disk. It is a data storage technology where multiple disks are used for data redundancy and improving server performance.
This is helpful when the drive has issues, if in case one of the HDD fails the other drives gets live and starts behaving as primary HDD So that you do not face any downtime in case of HDD fail.
Types of RAID
There different type RAID levels based on the number of disk drives used and the function it performs. We’ll briefly explain some of them here:
RAID 1 comes with Data Mirroring without parity and requires minimum two drives. It is useful when you need more reliability as compared to data storage capacity.
RAID 5 comes with Block Level striping with distributed parity and requires minimum three drives. It uses all drives except one to operate so when there is disk failure the data can read from the distributed parity and there is no data loss.
What if I use R1Soft Backup?
This actually depends on what you are using the backup solution for. If you are using backup solution only for disaster recovery to avoid downtime then you may not need a backup solution when you are using RAID. There would be no downtime in case of HDD failure but if in case whole server goes down or if you mistakenly delete a file, database etc. R1Soft would be useful in restoring the data as soon as possible.
However, you would not be able to access the data from the RAID disk as you can do from your backup solution. So if you want to be able to access your backup data for other purposes then it is suggested that you use a backup solution for your data separately.
