Though, RAID 1 has the ability to backup one disk to another, you are still under the risk of system crash or virus attack, as well as other disaster, so backing up your operating system is very important, whenever you need to reinstall the operating system, you can restore the system quickly.
RAID 1 - Disk mirroring. Optimized for Redundancy
RAID 1 uses mirroring to write data to multiple drives. This means that when you write a file, the file is actually written to two disks. If one of the disks fails, you can simply replace it and rebuild the mirror.
The tradeoff with RAID 1 is cost. With RAID 1, you must purchase double the amount of storage space that your data requires.
Minimum number of drives: 2
Strengths: high performance; high data protection; minimal penalty on write performance.
Weaknesses: High redundancy cost overhead; because all data is duplicated, twice the storage capacity is required.
Generally, RAID 1 is used to install operating system, whenever one disk failed, you can still use another disk of this RAID. To use RAID 1, you need to connect two disks to the RAID card and construct a RAID 1. After that, the RAID array is detected as a physical hard disk, and then you can install the operating system normally. BTW, this is different with software RAID 1 – Mirror Volume, to install operating system on Mirror Volume, you need to install the system on a basic disk firstly, after that convert to dynamic disk in Disk Management, at last add mirror with another free dynamic disk.
To free backup Windows Server RAID 1, you can work in Windows or by bootable disk. Choose "Backup" in the central place and follow the step by step instructions.
To restore the current system partition on RAID 1, you have to operate by bootable disk, but little product has RAID-compatible bootable disk, including the commercial products, but the free backup software - EAEUS Todo Backup provides the feature to free backup Windows Server RAID 1 and restore by WinPE bootable disk.
1. Put the WinPE bootable disk in to the CD-ROM, set CD-ROM as first boot device in BIOS and then boot from this disk.
2. Click "Restore" in central place or "Operation" -> "Restore" from menu bar
3. Select the backup archive you want to restore.
4. Select the partition of the image archive you want to recover. Click "Next".
5. Choose a target partition or unallocated space.
6. Select a partition type for the target partition.
7. After all these steps, you will successfully restore system partition. Take out the bootable CD from CD-ROM and reboot.
