AWS Glacier: Delete vault

Follow these steps to remove all archives from an AWS vault. After this is finished, you will be able to delete the vault itself through the browser console.

Step 1 / Retrieve inventory

This will create a job that collects required information about the vault.

$ aws glacier initiate-job --job-parameters '{"Type": "inventory-retrieval"}' --account-id YOUR_ACCOUNT_ID --region YOUR_REGION --vault-name YOUR_VAULT_NAME

Squid

Squid is a HTTP(S) caching proxy to reduce bandwidth and improves response times.

data compression proxy

Data compression proxy is a http proxy by google aimming to reduce cellular data usage by gzip and webp (Yes, it will compress jpg, png and gif to webp).

Squid + data compression proxy

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
H: preserves hard-links
A: preserves ACLs

	#!/bin/bash

	# ssh-cipher-benchmark.sh - Assesses speed of SSH encryption between specific hosts.
	# Usage:
	# ssh-cipher-benchmark.sh <remotehost> [ciphers]
	# Default ciphers: all we can find...
	#
	# Note: In some cases, the first cipher tested runs faster than the others, regardless of order.
	# Cause of this is not known, but changing the order of testing shows it to be true. Run the
	# first one twice if you suspect this. Perhaps it is due to buffering?
