AWS S3
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
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

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
4. Delete multiple files...
aws --profile customer2 s3 rm --dryrun --recursive --exclude "*" --include "messages" s3://mybucket/folder/ (dryrun) delete: s3://mybucket/folder/subfolder/messages
5. Make bucket...
aws s3 mb s3://mybucket --region eu-west-1
6. Create folder... (the key here is the forward slash / at the end)
aws s3api put-object --bucket mybucket --key dir-test/
7. Create folder and sub folders... (the key here is the forward slash / at the end)
aws s3api put-object --bucket mybucket --key dir-test/subfolder1/subfolder2/
8. Size and Number of Files...
aws s3api list-objects --bucket mybucket --output json --query "[sum(Contents[].Size), length(Contents[])]"
9. Copy files from remote storage to local...
aws s3 cp --recursive s3://mybucket/myFolder/ ./path/to/folder/
10. Restore file from Glacier storage...
aws --profile=default s3api restore-object --bucket mybucket --key foldername/file.zip --restore-request '{"Days":7,"GlacierJobParameters":{"Tier":"Standard"}}'
11. Upload folder to S3 as a tar.gz file without compressing locally first using pipes...
tar cvfz - /var/test | aws s3 cp - s3://mybucket/test1.tar.gz
12. Search for a filename...
aws --profile myprofile s3api list-objects --bucket files.mydomain.com --query "Contents[?contains(Key, '*S1255*')]" aws --profile myprofile s3 ls s3://files.mydomain.com/ --recursive |grep 'S1255'
13. Empty bucket but keep CPU usage low about 30% ...
sudo apt install cpulimit /usr/bin/cpulimit -q -b -c 1 -e aws -l 30 nice aws s3 rm --quiet s3://my.bucket.name --recursive
https://github.com/aws/aws-cli/issues/3163
A better way is to set a lifecycle policy and then let AWS do all the hard work rather than waiting on a command to finish :)
14. Find out if your buckets have versioning enabled...
#!/bin/bash
for bucket in $(aws s3api list-buckets --query "Buckets[].Name" --output text); do
result=$(aws s3api get-bucket-versioning --bucket ${bucket} --output text)
echo "${bucket}: ${result}"
done
exit;
15. List buckets (quickly using API)...
for bucket in $(aws s3api list-buckets --query "Buckets[].Name" --output text); do echo "${bucket}"; done;
16. List buckets and number each one...
(for bucket in $(aws s3api list-buckets --query "Buckets[].Name" --output text); do echo "${bucket}"; done;) >/tmp/buckets.txt; nl /tmp/buckets.txt

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.
