S3 or Amazon Simple Storage Service provides a simple web-services interface that can be used to store and retrieve any amount of data, at any time, from anywhere on the web. It gives any developer access to the same highly scalable, reliable, secure, fast, inexpensive infrastructure that Amazon uses to run its own global network of web sites. The service aims to maximize benefits of scale and to pass those benefits on to developers.

INFO:

AWS Free Tier

Includes 5GB storage, 20,000 Get Requests, and 2,000 Put Requests with Amazon S3.

Optimising Costs

Optimise Your Amazon S3 Costs

How to analyze and reduce S3 storage usage

Costs Example

Monthly cost of storing in S3 Standard: 753.27 GB x $0.024/GB = $18.08

Monthly cost of storing in S3 Glacier: $3.67
  753.27 GB x $0.0045/GB = $3.39
  Glacier overhead: 855953 objects * 32 KB * $0.0045/GB = $0.12
  S3 overhead: 855953 objects * 8 KB * $0.024/GB = $0.16

s3cmd

S3cmd is a tool for managing objects in Amazon S3 storage. It allows for making and removing "buckets" and uploading, downloading and removing "objects" from these buckets. It runs on Linux and Mac.

HOWTO:

Static Web Site

Create an S3 Bucket from AWS CLI

Create an S3 bucket in the us-east-1 region, giving your bucket a globally unique name, using the S3 API:

aws s3api create-bucket --bucket <UNIQUE_BUCKET_NAME> --region=<REGION> --create-bucket-configuration LocationConstraint=<REGION> --acl public-read

Modify the Newly Created Bucket to Be an S3 Website Bucket

Issue the AWS S3 API CLI command to enable the "Static website hosting" property of your bucket. In this same command, you'll also provide the index.html page, which is what your bucket URL will serve:

aws s3 website s3://<UNIQUE_BUCKET_NAME> --index-document index.html

Modify Provided S3 Policy File and Use It to Modify Bucket Policy

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "PublicReadGetObject",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::mybucketname/*"
        }
    ]
}

Put in the name of your bucket.

Save and exit the file.

Use the S3 policy file to modify the bucket policy so your objects are publicly accessible, which is a requirement for S3 static websites:

aws s3api put-bucket-policy --bucket <UNIQUE_BUCKET_NAME> --policy file://policy_s3.json

Create a Basic index.html Page and Upload File

Create a basic HTML page:

echo "<html><center><h1>My Static Website on S3</h1></center></html>" > index.html

Upload the index.html file to your S3 website bucket using the AWS S3 API CLI:

aws s3 cp index.html s3://<UNIQUE_BUCKET_NAME>

Verify Your S3 Static Website Is Working

Enter the S3 website URL for your bucket in the browser to ensure it's working.

You can also test from the terminal using the curl command:

curl http://<UNIQUE_BUCKET_NAME>.s3-website.us-east-1.amazonaws.com

CLI_Examples

https://www.thegeekstuff.com/2019/04/aws-s3-cli-examples/

1. To backup photos in your Syncthing directory (dryrun option added for testing)...

aws s3 sync --dryrun --exclude "*" --include "*201701*" /home/user/Syncthing/User/phone/photos/ s3://user.name.bucket/Photos/2017/01/
#!/bin/bash
#
# script to backup photos (taken the day before) to aws s3
#
YEAR=$( date +'%Y' -d "yesterday" )
MONTH=$( date +'%m' -d "yesterday" )
/usr/local/bin/aws s3 sync --exclude "*" --include "*${YEAR}${MONTH}*" /home/user/Syncthing/User/phone/photos/ s3://user.name.bucket/Photos/${YEAR}/${MONTH}/
exit

2. To move objects from one bucket to another bucket, or same bucket but different folder...

aws s3 mv s3://source/file1.txt s3://destination/file2.txt

aws s3 mv s3://source/file1.txt s3://source/folder/file1.txt

aws --profile profile2 s3 mv --dryrun --recursive --exclude "*" --include "archive-nfs/201502*" s3://source/ s3://destination/archive-nfs/MailArchive/

3. To use a different profile (for different customers)...

nano ~/.aws/credentials

[default]
aws_access_key_id = XXXXXX
aws_secret_access_key = XXXXXXXXXXXXX

[customer2]
aws_access_key_id = XXXXXX
aws_secret_access_key = XXXXXXXXXXXXX
aws --profile customer2 s3 ls

Thanks - http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html#cli-multiple-profiles

CLI Backup and File Versioning

Make S3 bucket...

aws s3 mb s3://bucketname.archive-test

Create S3 bucket archiving policy...

Example 1 = move all objects to Infrequent Access after 30 days, and then to Glacier after 60 days ...

nano aws_lifecycle_30_IA_60_GLACIER.json

{
    "Rules": [
        {
            "Filter": {
                "Prefix": ""
            },
            "Status": "Enabled",
            "Transitions": [
                {
                    "Days": 30,
                    "StorageClass": "STANDARD_IA"
                },
                {
                    "Days": 60,
                    "StorageClass": "GLACIER"
                }
            ],
            "NoncurrentVersionTransitions": [
                {
                    "NoncurrentDays": 30,
                    "StorageClass": "STANDARD_IA"
                },
                {
                    "NoncurrentDays": 60,
                    "StorageClass": "GLACIER"
                }
            ],
            "ID": "30 Days Transfer to IA, 60 Days Transfer to Glacier"
        }
    ]
}

Example 2 = only keep 1 current version and 1 non-current version of a file after 1 day ...

{
    "Rules": [
        {
            "Expiration": {
                "ExpiredObjectDeleteMarker": true
            },
            "ID": "1 Days Versions",
            "Filter": {},
            "Status": "Enabled",
            "NoncurrentVersionExpiration": {
                "NoncurrentDays": 1,
                "NewerNoncurrentVersions": 1
            },
            "AbortIncompleteMultipartUpload": {
                "DaysAfterInitiation": 1
            }
        }
    ]
}

CLI s3 sync options

DESCRIPTION
      Syncs  directories  and S3 prefixes. Recursively copies new and updated
      files from the source directory to the destination. Only creates  fold-
      ers in the destination if they contain one or more files.
      See 'aws help' for descriptions of global parameters.

Create A Bucket

s3cmd mb s3://uniquename.subname.whatever

List Buckets

s3cmd ls

List Contents Of Buckets

s3cmd ls s3://uniquename.subname.whatever/

Create Directory

This is a bit strange but you have to upload a file to the whole folder tree that is not there. It will then create the folders and subfolders as part of the process.

s3cmd put /tmp/test.txt s3://uniquename.subname.whatever/folder/subfolder/test.txt

Upload Files (Test)

s3cmd put --recursive --dry-run ~/folder s3://uniquename.subname.whatever/

Upload Files

s3cmd put --recursive ~/folder s3://uniquename.subname.whatever/

Sync Files

s3cmd sync --verbose ~/folder s3://uniquename.subname.whatever/

Sync File WITH DELETE

This will delete files from S3 that do not exist on your local drive.

This will allow you to clear up your local drive and S3 bucket at the same time.

!! USE WITH CAUTION !!

s3cmd sync --verbose ~/folder --delete-removed s3://uniquename.subname.whatever/

Lifecycle Storage Management with Glacier

Because Amazon S3 maintains the mapping between your user-defined object name and Amazon Glacier’s system-defined identifier, Amazon S3 objects that are stored using the Amazon Glacier option are only accessible through the Amazon S3 APIs or the Amazon S3 Management Console.

To put this in slightly simpler terms, S3 doesn't create Glacier archives that you own or can manipulate. S3 creates Glacier archives that S3 owns and manages.

Your only interface to these objects is through S3, which makes requests to Glacier on your behalf. So, for your questions, the answer for each one is essentially the same:

It doesn't matter. The archives are managed by S3 and are not user-accessible via the Glacier API or console.
