In the bad old days, the glacier class used to have different layers.

import boto.glacier.layer2l2 = boto.glacier.layer2.Layer2(aws_access_key_id='xxx', aws_secret_access_key='xxx')

import boto3gc = boto3.client("glacier",aws_access_key_id="xxx", aws_secret_access_key="xxx",)

shantanuo — Tue, 10 Sep 2019 13:03:59 GMT

lsblkNAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTxvda 202:0 0 8G 0 disk└─xvda1 202:1 0 8G 0 part /xvdf 202:80 0 90G 0 disk
