Hello to all,
As many here I have a nas at home hosting documents, family photos, and more.
My important stuff being the documents and photos, standing currently at 800GB and growing at around 50GB a year.
Following the 3-2-1 backup strategy, i need an offsite backup. I currently swap an external HDD at my in laws once a year, which is suboptimal
Looking into cloud offering everything is crazy expensive (i.e costs as much as buying a new drive every 6 months). Even looking into cold storage services, the prices don't drop much.
I'm starting to think about some exotic solutions like storing my HDD in 1 sealed box buried in my garden. This is not technically off-site, but good enough (fire and lightning proof).
Any tips for a good price/convenience compromise?
