S3Expressis a command line software utility for Windows. Easily upload, query, backup files and folders to Amazon S3 storage, based upon multiple flexible criteria. Create custom batch scripts, list Amazon S3 files or entire folders, filter them with conditions, query, change object metadata and ACLs. Content in the local windows folders can be synchronized with the AWS S3 buckets. This feature in AWS is helpful to ensure the files on the local computer are identical to those in Cloud storage (AWS S3). The synchronization steps are discussed here to familiarize and be reference guidelines for configuration of the AWS.

Introduction

S3Express is a command line software utility for Windows. Easily upload, query, backup files and folders to Amazon S3 storage, based upon multiple flexible criteria. Create custom batch scripts, list Amazon S3 files or entire folders, filter them with conditions, query, change object metadata and ACLs. Quickly upload only new or changed file using multipart uploads and concurrent threads.

S3Express Main Features

Windows Command Line Utility for Amazon Simple Storage Service S3.

Very compact, very small footprint: the entire program is less than 5MB. Self-contained in one executable, S3Express does not require any additional libraries or software to be installed to run.

List S3 objects with conditional filters - manage S3 objects' metadata and ACLs - upload files using multipart uploads and multiple concurrent threads - upload only new or changed files (incremental backup) - delete multiple S3 objects - copy S3 objects - server-side and local encryption supported - and much more...

S3Express is ideal for batch scripts, automated uploads and backups to Amazon S3, and for performing custom queries on Amazon S3 objects.

All S3Express operations are multithreaded (fast), automatically retryable (network-failure resistant) and interruptible (= all commands can be stopped and restarted at any time). Connections to Amazon S3 are made using secure http (https), which is an encrypted version of the HTTP protocol, to protect your files while they're in transit to and from Amazon S3.You will not find many S3 command line tools that can do that!

Works on all versions of Windows including all Windows Servers.

It can easily handle several million files and files as large as 100GB or more in multipart mode.

Sold, actively supported and maintained by TGRMN Software.

It's Easy and Quick to Install. Download the free 21-day trial and start using S3Express today.

Detailed Feature List

General

· All S3Express operations are multithreaded to achieve maximum speed.

Google Photos Uploader Windows 10

· All S3Express operations are automatically retried on error (after X seconds and for X times, customizable)

· All S3Express operations are interruptible and then restartable by simply pressing the key 'ESC'.

· All S3Express connections to Amazon S3 are made using secure http (https) to protect your files while they're in transit to and from Amazon S3 servers.

· Command line variables supported.

· Scripting via the command line supported.

· Unicode compatible, i.e. S3Express supports all alphabet characters in the world.

List S3 Objects

· List objects in one or more S3 buckets and optionally show metadata and ACL for each object.

· List objects only in a specified subfolder or recursively list all objects in all subfolders.

· Optionally include all versions of an object in the listing for buckets that have versioning enabled.

· Include / exclude objects from the listing based on name, size, metadata, ACL, storage-class, encryption status, etc.

· Filter listing using regular expressions or basic wildcards.

· Show listing summary only and group S3 objects by extension, date, subfolder and more.

· For example, list all objects with 'cache-control' header not set or 'cache-control' header not equal to a specified value.

· For example, list only all public objects or only all private objects or only objects with a specified ACL.

· For example, list all object whose size is larger than a specified value.

· More than 25 different options available for the ls (list) command.

Upload Files to S3

· Upload multiple files and whole directories to Amazon S3.

· Uploads are fully restartable in case of failure.

· Uploads can be automatically retried in case of an error (after X seconds and for X times, customizable).

· Optimized parallel file transfers (multiple threads) to speed-up uploads.

· Upload files using multipart uploads (with correct MD5 value) and multiple threads, so that large uploads can be restarted at any time from where they were left, if interrupted.

· Server-side and/or client-side file encryption supported.

· Keep the existing ACLs and/or metadata when overwriting existing S3 files.

· Throttle maximum bandwidth to use in Kilobytes per second.

· Select files to upload based on name, extension, size, subfolder, time, etc.

· Copy objects instead of re-uploading if a matching object is found on S3, so that renaming an object does not require re-uploading again.

· Move local files to Amazon S3 after successful upload, based on flexible criteria, e.g. file age, name, size etc.

· More than 24 different options available for the put (upload) command.

Incremental Backup to S3

· Upload only new and changed files. Using this type of upload you can perform fast, incremental backups to S3: only those files that are new or have changed, compared to the files that are already on S3, are uploaded. And if a file is renamed locally, the corresponding S3 file is copied not re-uploaded to save time and bandwidth.

· Optionally, if a file is deleted locally, the corresponding S3 file can be removed or archived.

Manage S3 Metadata

· Show all or just specific object metadata.

· Set, reset, replace one or multiple objects' metadata.

· Preview all operations before proceeding.

· For example, set multiple objects' 'cache-control' header to a certain value.

· See the setmeta and getmeta commands.

Manage S3 ACLs

· Show all or specific object ACLs

· Set, reset, replace one or multiple objects' ACLs.

· Preview all operations before proceeding.

· For example, set multiple objects to public access.

1. Open the IAM console.

S3 Uploader Windows

2. Choose Roles, and then choose Create role.

3. Select AWS Service, and then choose EC2.

Note: Creating an IAM role from the console with EC2 selected as the trusted entity automatically creates an IAM instance profile with the same name as the role name. However, if the role is created using the AWS Command Line Interface (AWS CLI) or from the API, an instance profile isn't automatically created. For more information, refer to I created an IAM role, but the role doesn't appear in the drop-down list when I launch an instance. What do I do?

4. Select Next: Permissions.

5. Create a custom policy that provides the minimum required permissions to access your S3 bucket. For instructions on creating custom policies, see Writing IAM policies: how to grant access to an Amazon S3 bucket and Managing access to S3 resources.

Note: Creating a policy with the minimum required permissions is a security best practice. However, to allow EC2 access to all your Amazon S3 buckets, you can use the AmazonS3ReadOnlyAccess or AmazonS3FullAccess managed IAM policy.

6. Select Next: Tags, and then select Next: Review.
