I want to download million of files from S3 bucket which will take more than a week to be downloaded one by one - any way/ any command to download those files in parallel using shell script ?
Thanks,
AWS CLI
You can certainly issue GetObject requests in parallel. In fact, the AWS Command-Line Interface (CLI) does exactly that when transferring files, so that it can take advantage of available bandwidth. The aws s3 sync command will transfer the content in parallel.
See: AWS CLI S3 Configuration
If your bucket has a large number of objects, it can take a long time to list the contents of the bucket. Therefore, you might want to sync the bucket by prefix (folder) rather than trying it all at once.
AWS DataSync
You might instead want to use AWS DataSync:
AWS DataSync is an online data transfer service that simplifies, automates, and accelerates copying large amounts of data to and from AWS storage services over the internet or AWS Direct Connect... Move active datasets rapidly over the network into Amazon S3, Amazon EFS, or Amazon FSx for Windows File Server. DataSync includes automatic encryption and data integrity validation to help make sure that your data arrives securely, intact, and ready to use.
DataSync uses a protocol that takes full advantage of available bandwidth and will manage the parallel downloading of content. A fee of $0.0125 per GB applies.
AWS Snowball
Another option is to use AWS Snowcone (8TB) or AWS Snowball (50TB or 80TB), which are physical devices that you can pre-load with content from S3 and have it shipped to your location. You then connect it to your network and download the data. (It works in reverse too, for uploading bulk data to Amazon S3).

Im trying to have a replica of my s3 bucket in a local folder. it should be updated when a change occurs on the bucket.
You can use the aws cli s3 sync command to copy ('synchronize') files from an Amazon S3 bucket to a local drive.
To have it update frequently, you could schedule it as a Windows Scheduled Tasks. Please note that it will be making frequent calls to AWS, which will incur API charges ($0.005 per 1000 requests).
Alternatively, you could use utilities that 'mount' an Amazon S3 bucket as a drive (Tntdrive, Cloudberry, Mountain Duck, etc). I'm not sure how they detect changes -- they possibly create a 'virtual drive' where the data is not actually downloaded until it is accessed.
You can use rclone and Winfsp to mount S3 as a drive.
Though this might not be a 'mount' in traditional terms.
You will need to setup a task scheduler for a continuous sync.

I have a requirement where we need to move files from on-prem NAS storage to AWS S3.
Files keep coming on NAS storage when it arrives we have notification set up in AWS and then we need to pull files from AWS to S3.
Can I access NAS storage and pull files from AWS to S3?
Does it require any additional configuration or simple EC2 or Lambda function can work based on size of the file?
How about NAS --> SFTP --> S3 using AWS Transfer family solution.
Is there any better way to move files from NAS to S3?
We want to avoid writing code as much as we can.
You should take a look at AWS Datasync.
It is a data transfer service of AWS that allow to copy data to and from AWS storage services over the Internet or over AWS Direct Connect (protocols NFS, SMB).
You don't need EC2 or AWS lambda. You have to install an agent that will read from a source location, and sync your data to S3. The agent is deployed on-premise. Please find the supported Hypervisor here: https://docs.aws.amazon.com/datasync/latest/userguide/agent-requirements.html and the deployment guide here: https://docs.aws.amazon.com/datasync/latest/userguide/deploy-agents.html
I have a requirement to transfer data(one time) from on prem to AWS S3. The data size is around 1 TB. I was going through AWS Datasync, Snowball etc... But these managed services are better to migrate if the data is in petabytes. Can someone suggest me the best way to transfer the data in a secured way cost effectively
You can use the AWS Command-Line Interface (CLI). This command will copy data to Amazon S3:
aws s3 sync c:/MyDir s3://my-bucket/
If there is a network failure or timeout, simply run the command again. It only copies files that are not already present in the destination.
The time taken will depend upon the speed of your Internet connection.
You could also consider using AWS Snowball, which is a piece of hardware that is sent to your location. It can hold 50TB of data and costs $200.
If you have no specific requirements (apart from the fact that it needs to be encrypted and the file-size is 1TB) then I would suggest you stick to something plain and simple. S3 supports an object size of 5TB so you wouldn't run into trouble. I don't know if your data is made up of many smaller files or 1 big file (or zip) but in essence its all the same. Since the end-points or all encrypted you should be fine (if your worried, you can encrypt your files before and they will be encrypted while stored (if its backup of something). To get to the point, you can use API tools for transfer or just file-explorer type of tools which have also connectivity to S3 (e.g. https://www.cloudberrylab.com/explorer/amazon-s3.aspx). some other point: cost-effectiviness of storage/transfer all depends on how frequent you need the data, if just a backup or just in case. archiving to glacier is much cheaper.
1 TB is large but it's not so large that it'll take you weeks to get your data onto S3. However if you don't have a good upload speed, use Snowball.
https://aws.amazon.com/snowball/
Snowball is a device shipped to you which can hold up to 100TB. You load your data onto it and ship it back to AWS and they'll upload it to the S3 bucket you specify when loading the data.
This can be done in multiple ways.
Using AWS Cli, we can copy files from local to S3
AWS Transfer using FTP or SFTP (AWS SFTP)

There are tools like cloudberry clients which has a UI interface
You can use AWS DataSync Tool
I need to copy some buckets from one account to another. I got all permissions so I started transferring the data via cli (cp command). I am operating on a c4.large. The problem is that there is pretty much data (9tb) and it goes realy slow. In 20 minutes I transferred like 20gb...
I checked the internet speed and the download is 3000Mbit/s and the upload is 500 Mbit/s. How can I speed up it?
The AWS Command-Line Interface (CLI) aws s3 cp command simply sends the copy request to Amazon S3. The data is transferred between the Amazon S3 buckets without downloading to your computer. Therefore, the size and bandwidth of the computer issuing the command is not related to the speed of data transfer.
It is likely that the aws s3 cp command is only copying a small number of files simultaneously. You could increase the speed by setting the max_concurrent_requests parameter to a higher value:
aws configure set default.s3.max_concurrent_requests 20

My organization is evaluating options of Hybrid Data Warehouse using AWS Redshift and S3. Objective is to process the data on-premises and send processed copy to S3 and then load to Redshift for visualization.
As we are in initial stages, there is no file/storage gateway setup yet.
Initially we used Informatica Cloud tool to upload data from on-premises server to AWS S3, but was taking long time. Data volume is few hundred million records in history and few thousand records in daily incremental.
Now I have created custom UNIX scripts using AWS CLI and using CP command to transfer files between on-premises server and AWS S3 in gzip compressed format.
This option is working fine.
But would like to understand from experts, if this is the right way of doing it or if there are any other optimized approaches available to achieve this.
If the volume of your data is more than 100 mb then AWS suggest to use Multipart upload for better performance.
