[Duplicity-talk] Glacier, 2018 edition

[Oliver Cole]

Hi,

I see discussion about Glacier in the archives, but nothing recently.

What's the current state of Duplicity + Glacier? Is anyone doing this 
for real?

Can duplicity manage the migration to Glacier for me, or do I need to 
setup bucket policies myself?

I'm somewhat new to duplicity - would I be configuring it to do 
incremental backups, and then a full backup every 100 days or so? Would 
that then result in the previous full+incrementals being deleted 
automatically?

What if I wanted to go 100% incremental (after the initial full)? 
Obviously I would be at risk of one corrupt backup breaking all the 
subsequent incrementals, but would that be a possible route if I was 
happy with the risk?

I'm not quite up on the duplicity terminology - but what are the 
situations where duplicity would need to retrieve metadata from Glacier 
(and hence incur some significant costs or time delay)? Is there a way 
to keep the metadata in S3 and only migrate the raw data to Glacier?

I've read the warning: 
https://medium.com/@karppinen/how-i-ended-up-paying-150-for-a-single-60gb-download-from-amazon-glacier-6cb77b288c3e
It was updated to say that 'The “gotcha” pricing described herein is no 
longer in effect, replaced by simple per-GB retrieval fees.'
Are people generally happy with this now?
