Question about software RAID and recover senerio

post #1 of 4
Thread Starter 
Hey Linux heads! I've been rolling this around in my head for a bit and I'm not sure what the best solution would be for my scenario.

I want to install ubuntu on a new workstation down the road (waiting for zen) and I plan on having a single boot drive (intel 750 series pci e ssd) that I would like to run nightly backups to a software raid 1 +0 or 5 array. My question is if I go with software RAID and my boot drive tanks how would I go about accessing the backups on the software raid array ? I really don't want to add a dedicated controller do to the added cost (this build is adding up quick). Thanks for your input!

My meager understanding of it is that using pure software RAID is easily recoverable. If the OS drive has an issue, you could replace it with a fully functioning drive, or even use a live DVD/USB to access your data. You could also migrate the drives to another PC. Basically the same with hardware RAID. Using a cheap built-in motherboard controller adds the extra layer of failure that if the motherboard dies, you need to find the same type of controller to recover data. At least that is what was explained in the Linux RAID guide i read a few weeks ago.

Thanks for the reply, so say the OS tanks, I could theoretically load up a new os and mount the software RAID array ? I guess my other question is how a new OS would associate a software RAID configuration that was build by another OS? Doesn't the OS hold the configuration of the RAID since it was built on the OS ?

As long as it isn't encrypted it should be able to be read by any Linux OS without issue. I'm no expert at this, so it would be a good idea to read through the link I posted to get a proper understanding of how it all works. It seems like a lot of this stuff is controlled at the kernel level, so as long as you don't dig up some ancient OS based on a really old kernel then it should just work.
