Multi platform data backup on two HDDs

[Don Bee]

Hi.

I use Windows and Linux on my PC for gaming and college. I have an SSD where I have both my OS and two hard drives. I want to use one HDD as the backup of the other. I've thought about using RAID-1, but I don't know if that would work with both OS. I haven't found any tool that allows me to make this backup multiplatform. Does something like this exist?

Thanks.

Firstly. RAID is not a backup. http://www.petemarovichimages.com/2013/11/24/never-use-a-raid-as-your-backup-system/
To make RAID 1 of two drives you need either a software or a hardware controller. Using MDADM, ZFS, etc. you can make a software RAID 1. The problem is that such a configuration can not be moved from the OS. It depends on the OS configuration. Connecting those drives to another system would not let you read data on that drives as the OS knows nothing about the configured RAID.

 

Meanwhile hardware RAID, in particular, external 2-disk USB enclosures allows set up RAID 1 with 2 disks and use it as external unmountable and portable storage. https://www.amazon.com/HornetTek-USB-Dual-Enclosure-RAID/dp/B019WWIRQU/ref=sr_1_48?dchild=1&keywords=usb+raid+enclosure&qid=1586733073&sr=8-48

 

With your hardware setup, I would use Veeam Endpoint to backup data to each drive in order to have at least 3 copies of the data. Consider adding another media such as cloud storage as a backup tier. This way you could have a bullet-proof backup. https://www.vmwareblog.org/3-2-1-backup-rule-data-will-always-survive/
