Glacier is about $1USD/TB/month just for storing data. If you need to retrieve it ends up being about $90USD/TB, most of that is bandwidth charges.

That means that if you store the data for much more than a half of year, Glacier becomes more expensive than storing on tapes.
Of course, tapes require a tape drive and its cost would require a lot of data to compensate the cost, but at a such high cost of retrieval it would not take much data to equal the cost of a tape drive.
Glacier is OK for a couple of TB, but for tens or hundreds it would not be suitable.

But the less you expect to use it, the less this matters.
So I'd put the break-even point a bit higher. Tape is good for 100TB or more but for tens it's hard to justify a tape drive.
Also it's important to remember to get those tapes offsite every week!
