How to Backup RAID 0 to A Single Hard Drive?

“ I'm wondering if it's possible to set up two drives in a RAID 0 array and then back them up to a single drive (twice the size obviously) in case of failure of either drive. What should i do? Any input would be greatly appreciated.”

Before backup RAID 0 drive, please get a glance at the RAID 0.

What is RAID 0?

RAID (Redundant Arrays of Independent Disks) 0 is also called Stripe or Striping and it represents the highest level of storage performance. RAID 0 disperses data across two or more hard disks uniformly.

For example, if the RAID 0 owns two drives, the first striped data will be saved to the first disk, the second will be saved on the second disk, the third striped data will be stored on the first disk, the fourth will be written to the second disk, so and forth.

In most cases, people use RAID 0 to improve disk performance or to combine two small physical disks into a larger logical one.


By the way, you could make a RAID 0 striped with two or more disks with different sizes. The total storage space of RAID 0 is determined by the size of the smallest disk. For instance, when a 300 GB disk is striped together with a 500 GB disk, the total size of the RAID 0 array will be 600 GB (300×2).

Does RAID 0 Safe?

As a matter of fact, It’s not safe to use RAID 0. Unlike other levels of RAID arrays, Raid 0 provides no data redundancy due to the data storage method mentioned above. RAID 0 is not a backup, if any one of the RAID 0 be damaged, and the whole data on the RAID 0 will be gone totally. It means that you cannot recover data from RAID 0. The best situation is that you can just recover a little data from the other disk that is working well in RAID 0.

Therefore, please backup RAID 0 drive to a single drive to get everything protected.

Best Free RAID 0 Drive Backup Software

Considering no data redundancy of RAID 0, it’s urgent for you to backup RAID 0 drives. Hence, It’s strongly recommended that try the best free RAID backup software - AOMEI Backupper Standard to protect everything on your RAID 0 hard drives.

It is not only a backup and restore software but also the disk cloning software, which allows you clone hard drive without losing data, clone data partition to another partition, automatically sync files to destination as you want.

AOMEI Backupper supports the following storage devices, like IDE, NVMe, SATA, SCSI, SSD, USB external disks, hardware RAID, Network Attached Storage (NAS) and so on, including MBR and GPT disk.

How to Backup Data Safely in RAID 0 Drives?

Please download the free backup software and have it a try:

Download Freeware Win 10/8.1/8/7/XP
Secure Download

Here are the steps to backup data on your RAID 0 in Windows 7/8/10: 

1. Perform the RAID backup software - AOMEI Backupper Standard, select Backup > Disk Backup in turn.

Disk Backup

2. Click + Add Disk button > choose the RAID 0 drive and hit Add to select the RAID 0 as source disk.

Add Disk

Select RAID 0

3. Select a destination for the RAID 0 drive backup image file.

Select Backup Destination

4. Press Start Backup >> to backup RAID 0 disk safely.

Start Backup RAID 0

There are some settings you could specify before starting backup (Optional):
✍Options: It allows you to comment, compress, split, encrypt(paid) the disk backup image, enable email notification, etc.
✍Schedule: This option offers you five modes to automatically backup data on RAID 0 on a regular basis, like daily, weekly, monthly, event triggers, USB plug in. It’s especially useful if you are too busy to do the RAID 0 drive backup manually. Please upgrade to enjoy the last two modes.
✍Scheme setting is capable of deleting old backup images automatically if the destination is run out of storage space.

All the data on the RAID 0 will be backed up safely. If any of the RAID 0 drives failed, you could replace the corrupted one with the new one, and restore data to the new hard disk at once.

And most importantly, AOMEI Backupper Standard allows you to create incremental and differential backup to backup the changed or modified files since the last (full) backup.

Besides, you could sync files to another safe location on a regular basis to protect your crucial data (no compression). Or you could sync the data on the RAID 0 drive with the Real Time Sync feature, which is available in AOMEI Backupper Professional. After the first full synchronization, it will sync the changed or newly added part to the location.

RAID 0 Drive Recovery

If you encounter a hardware failure in RAID 0, you could do the following to perform RAID 0 drive recovery.

1. Select Restore tab, and then choose Select Image File.

Select Backup Image

2. Find the RAID 0 drive backup image file, tick Restore the entire disk, and click the entire disk listed below to restore, and hit Next >>.

3. Choose the RAID 0 drive as destination.

4. Press Start Restore >> to do RAID 0 drive recovery.

Further Reading: The Common RAID Levels

There are some common RAID levels that you may want to try:

  • RAID 0, striping, at least 2 hard disks.

  • RAID 1, also called disk mirroring, the most expensive disk array. It requires at least two disks.

  • RAID 5, named disk striping with parity, the most common RAID level which achieves a good balance both on performance and redundancy.

  • RAID 10, striping and mirroring. At least four hard disks. It’s fast and secure.

  • RAID 50, requires at least 6 drives. It’s the combination of RAID 5 and RAID 0.

In the End

RAID 0 drive backup is not difficult for you as long as you find the right RAID backup software - AOMEI Backupper Standard. Besides, The premium edition - AOMEI Backupper Professional allows you to clone HDD to SSD to speed up your computer performance, migrate Windows 10 to SSD without reinstalling, clone MBR to GPT disk or vice versa, etc.
