How to backup a raid array?


RAID is short for Redundant Arrays of Independent Disks and it works to automatically and instantaneously mirror or duplicate your data, allowing for real-time backup.

There are many levels of RAID, and they come with advantages and disadvantages but the most common are:

  • RAID 0 – For striping and comes with at least 2 hard disks
  • RAID 1 – Also known as mirroring disk, it is the most expensive disk array. RAID 1 needs at least two disks to work.
  • RAID 5 – Considered as disk striping with parity, it is the most common RAID level used. It delivers the right balance of performance and redundancy.
  • RAID 10 – This is for striping and mirroring. It is a fast and secure array and requires at least four hard disks.
  • RAID 50 – This array requires at least 6 drives. It’s a combination of RAID 0 and RAID 5.

To better understand the different levels of RAID, you can check this video:

Many users prefer RAID 0 because of how it improves performance and combines smaller disks into a larger one. However, unlike other RAID levels, RAID 0 does not come with a redundancy feature and it does not work as a backup. This means that if your RAID 0 is damaged, all your data will be lost totally. That is why it is important to backup your RAID array to another drive.

In this guide, we will discuss how to backup a RAID array, particularly RAID 0.

Backing up a RAID Array

The easiest way to backup a RAID array is by using third-party software. While there are different software available, the steps to backup a RAID array may be very similar across these applications.

The general steps include installing the third-party software on your computer and then opening its associated app. From there, go ahead with the disc backup commands that will be prompted on your screen.

At some point, you’ll be required to add the disk button and from there, you should select RAID 0 drive. This will tell your system to get data from RAID 0. After this, you also need to select a drive where you want to save the backup file.

Once you select the source and destination of your data, system backup should automatically start. But then again, these are just the general steps. Refer to your third-party software manual for the exact steps to initiate backup.

Q & A

What is RAID storage?

What is RAID storage? Redundant Array of Independent Disks (RAID) is a storage technology that creates a data loss fail-safe by merging two or more hard disk drives (HDDs) or solid-state drives (SSDs) into one cohesive storage unit, or array.

Why do you need to backup RAID 0?

RAID 0 does not work as a backup so when it gets damaged, all your day’s work will be gone totally.

How to backup a RAID array?

The most straightforward way to backup RAID is by using a third-party software. Simply refer to the application’s manual for the exact steps.

Can you back up on a RAID?

Is RAID a backup? While RAID arrays can provide enhanced data protection, their extra disks should not be considered as backups. If your main drive is a RAID array, you still need to back it up. If you have, say, 12 TB storage on a RAID array, you’ll want to back it up to another device.

What is a RAID backup?

RAID is a backup for a drive failing. Saying that it isn’t a hard drive would be like saying a hard drive which keeps a copy of all your data is not a backup because a hurricane could take both of them out at once. Before planning your backup solution you should first figure out what you are trying to defend against.

Is RAID the same as backup?

The main difference between RAID vs. backup is that, although backups help you recover from a data loss event, RAID exists as a tool for keeping data loss from happening in the first place.

What is the difference between redundancy and backup?

Backups are specifically about creating copies of data in the event that your business experiences an incident where data loss occurs. Redundancy, on the other hand, is much more than just data storage. Redundancy makes sure your business is able to provide continuity in its services no matter what happens.

Conclusion

It’s not that difficult to backup RAID. With the right software, the steps should be easy to follow and can be accomplished in just a few minutes.
