I'm the first one to admit that Glacier pricing is neither clear nor competetive regarding retreival fees. I do think that a lot of people use it the wrong way: as a cheap backup. I use:

1. My Time Machine backup (primary backup)

2. BackBlaze (secondary, offsite backup)

3. Amazon Glacier (tertiary, Amazon Ireland region)

I only store stuff that I can't afford to miss on Glacier: photos, family videos and some important documents. Glacier isn't my backup, it's the backup of my backup of my backup: it's my end-of-the-world-scenario backup. When my physical harddrive fails AND my backblaze account is compromised for some reason, only then will I need to retrieve files from Glacier. I chose the Ireland region so my most important files aren't even on the same physical contintent.

When things get so dire that I need to retrieve stuff from Glacier, I'd be happy to pony up 150 dollars. For the rest of it, the 90 cents a month fee is just a cheap insurance.
