Why do Windows users, especially server users need to backup RAID drive? This is easy to answer, but to RAID users, there are two questions they may ask, "Does the software compatible with RAID?" "Is it easy, safe and fast to clone RAID drive?" They have to find and compare with the candidates.
Is it possible to backup RAID in a safe and easy way? The answer is yes and this article will introduce a great solution to backup RAID with a RAID backup software.
What Is RAID
RAID stands for Redundant Array of Independent Disks, which is a technology that employs the simultaneous use of two or more hard disk drives to achieve greater levels of performance, reliability, and/or larger data volume sizes. When several physical disks are set up to use RAID technology, they are said to be in a RAID array which distributes data among several disks. Meanwhile, the array is seen as one single disk by the users and Operating System.
RAID makes use of two or more hard drives in order to improve performance, reliability or create larger data volumes. The former is achieved through striping, whereby data is split and written across multiple drives to increase throughput, and reliability can be improved by introducing redundancy. An example of this is a mirrored RAID array, whereby data is written to more than one disk so that in the event of a single disk failure, an exact copy of the original data still remains.
Usually, there are 3 most commonly used RAID levels as follows:
| Level | Description | Minimum No. of Disks | Image |
|---|---|---|---|
| RAID 0 | Striped set without parity/ [Non-Redundant Array]. | 2 |  |
| RAID 1 | Mirrored set without parity. | 2 |  |
| RAID 5 | Striped set with distributed parity. | 3 |  |
RAID is really used to its full potential in emergency services and business where data reliability and performance are essential. Meanwhile, backing up the operating system and RAID by the RAID backup software is important to avoid downtime.

Frequently Asked Questions
- What is the difference between Clone and Backup? In what cases should I use Clone?
-
Clone will copy one disk to another or one partition to another (unallocated space is also supported). Usually, this option is used to upgrade the current disk by creating an identical copy. Backup will generate a .PBD image file containing the selected files or system that can be restored from the .PBD image if needed.
- What is the difference between System Backup and Disk Backup?
-
System Backup will auto-select the system boot related partition(s) as the backup source to make sure the system image can be restored properly. Disk/Partition Backup will allow you to manually select a whole disk or speficy a certain partition as the backup source. You will get the same backup result as System Backup if you manually select the system and boot partitions with the Disk/Partition Backup option.
- As a computer newbie, what features should I use to protect my computer?
-
You can use System Backup to back up the system and boot partitions, use Disk/Partition backup to back up the data partition and add plans to run an automatic backup. If you use the computer frequently or have software that may cause boot failure of the computer, we would suggest you back up the computer every 1 to 2 days. For other situations, you can backup the computer once a week. In addition, you can schedule File Backup to back up the files which are changed frequently.
- What kind of storage service should I use to save my backup images?
-
EaseUS Todo Backup can save backup images to internal disks, external disks, network drives, or free cloud(Google Drive, Dropbox, and OneDrive) and CD/DVD. It is suggested to save the images to the internal/external/network drives to save time as those kinds of disks have a better read-write speed. It is suggested NOT to save the image on the source disk, because once the disk is damaged, all the files on the disk will become unavailable and you will be unable to restore the image.
- As a company network administrator, what features should I use to protect our internal computers?
-
It is recommended that you use the SQL Backup feature to back up your company's SQL server and Exchange Backup feature to back up the Exchange server. In addition, you can execute System Backup to back up the system and boot partitions on every computer and set a plan to execute the backup once a day or twice a week to ensure that the computer can be restored timely when it has boot issues. File Backup feature can be used to back up important user data. If there are a large quantity of computers, you can purchase EaseUS Backup Center to manage the backups on the client computers centrally.
