So I've been paying Backblaze to keep a backup of my HDD that stores all my important data. I recently switched my main OS to Linux, which is not supported by the consumer Backblaze product.
It got me thinking about how I could set up an off-site backup myself.
My idea is to set up a second HDD at my parents house, connected to their router via ethernet cable. I'm hoping there's a good way to configure my network drive with some kind of cron job that would mirror the contents of my network drive to the drive I'd set up at my parents house. That way if my house burned down or I got burgled, I'd still have an off-side duplicate of my lost HDD.
Is this a good idea? Are there considerations or pitfalls I should be aware of with a setup like this that might make me think twice? If it's a decent idea, I'd appreciate being pointed in the right direction as far as where to begin building a setup like this. Thanks!
