I’ve had a Drobo running since 2015 up in my closet dutifully keeping data spinning on the five drives inside of it.
Yesterday, while I was dealing with all the crap from my accident, I looked at the Drobo and it had a red light on. One of the five drives had failed. I quickly ordered a replacement (I’ll warranty the failed one and just keep it as a spare).
I removed the failed one and popped in the new one. It rebooted… and it’s all good.
And I didn’t lose any data.
That’s why I like having the backup like this.
(well, I also have a backup in the cloud as well, but I like having multiple layers of redundancy… I’m weird like that)
