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 This tool is exceptionally out of date.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.
