I actually use Arq to send my Time Machine backups and the rest of my NAS to S3 Glacier, in case the house burns down or the drives fail (whichever comes first). It works great and is very cheap!
I can’t code. What good is it for me if the code is open source ? I can’t vouch for it and I don’t know anyone who vouches for open source code. Also, I have a Mac. Try to find open source software that runs for four years straight without a hitch on Mac. Arq has done that for me.
Expensive external backups if I ever need it is better than none at all. It's a bet, but hey so is insurance.
EDIT: I checked your tool. It's a 1000 bucks to restore 4 TB in 48 hours. If the house burns down, insurance will cover that. I guess now I know I gotta check those drives a bit more.
What? This tool is exceptionally out of date. Retrieval cost is $30/TB at the high end, and for glacier deep archive and a 48 hour window it only costs $2.50/TB. (Plus a few cents per thousand requests, so maybe don't use tiny objects.)
Glacier's percentage-rate-based retrieval pricing was only active from 2012-2016.
The bandwidth charge of $90/TB is still accurate. Though there are ways to reduce it.
Why use closed source crypto for money when free software that can be reviewed is available gratis? There are much better options.
