RAID stands for Redundant Array of Independent Disks. A RAID-based storage array is a data storage system that uses multiple disks (or drives) to create a single logical unit. It provides greater performance, fault tolerance, and capacity than a single disk drive.
A RAID-based storage array is simply a storage device that uses RAID to combine multiple hard drives into one logical unit. This can be used to provide increased performance or fault tolerance, depending on how the array is configured.
Here we have mentioned some top suggestions to Prevent Data Loss in Your RAID-based Storage Array.
Don’t neglect the power of an updated backup
Regardless of whether you have a failure of the system or data loss, a data backup is a necessity. Some of the top organizations, SMBs in the world rely on the RAID-based storage array. Try not to trick yourself; RAID isn’t a backup. If you have a genuine RAID corruption/formatting/deletion, the data can vanish. An up-to-date backup, if put away accurately, is the best source to get your information back.

Get the suitable RAID configuration
Because various RAID configurations have various redundancies to forestall any data loss issue, it’s the right thing to make a design of your storage system that genuinely includes your provisions related to data loss. Single drives can fail eventually. At the point when this occurs, suppose if it’s RAID 1, the defective drive is replaceable and the data storage map can be remade without losing any information.
Never rebuild a system in cases of multiple disks failure
When you have a failure of two or more disks on a RAID 5 system, then you should never change the failed drives and do a rebuild of the system. It will definitely destroy your data forever. In cases of rebuilding, the process is too long because you are replacing the faulty drive with the new one.
In any case, assuming that something comes up short in the process, the rebuild activity will bring about extra risk. Always do a rebuild operation when you can depend on a backup.
Get ready for a failure of system or hardware
Assuming you have bought a RAID-based system from one producer, then every one of the hard drives utilized is from a similar group and creation date. Hence, it’s normal that they arrive at their end-of-life cycle at practically a similar time. Because of this reality, it’s totally important to check and screen the situation with the hard drives at the right time. On the off chance that one hard drive in a RAID 5 fails, don’t spare a moment to replace it right away. Holding up here too long can cause serious information loss.
Image and label the content inside the disks array before DIY rebuilding
In case, you have chosen to rebuild the RAID array on your own. Try to have an image of all drives so that you can do the RAID data recovery easily later (if the rebuilding operation fails).
If the rebuild process fails at say 10% then the content is overwritten and data is lost forever. That is why taking an image of hard disks inside the whole storage array before you start the rebuild is important. With these content images, RAID data recovery experts can help you with the process.

To sum up:
Checking to RAID health is important because the more intricate the storage system, the more convoluted it becomes to recuperate data in case of data loss.
RAID arrays have a mix of a few complex innovations in the systems, like virtualization and deduplication. These are advances that can cause failures that can’t be addressed easily. Solely after a profound examination from RAID data recovery experts, who can conclude the real issues and solve them.
