Hi@Rodrigo,

In the case of the Windows system, you need to use the SCP protocol. It will help to connect windows instance.

Hi@vijaykumar,

You can transfer file from ec2 instance to s3 bucket using lambda function.

Follow the below steps:

• Create an IAM role with s3FullAccess and Ec2FullAccess

• Create a s3 bucket

• create a lambda function and try to run the below code.

import json
import boto3
from pprint import pprint
def lambda_handler(event, context):
    client = boto3.client("ec2")
    s3 = boto3.client("s3")
    status = client.describe_instance_status(IncludeAllInstances = True)
    s3.upload_file("/home/test/sample.txt","bucket_name","testbk1122/testing/")
    return {
        'statusCode': 200,
        'body' : json.dumps('Hello from lambda')
    }

Make sure your EC2 instance is  in running status.

Hope it will help.

Thank You

my file is in ec2 under below path

/home/ubuntu/sk/amitt.txt  and while i am passing this path, getting error like path not found for this path.

Hi,

If it is showing path not found means you are sharing the wrong path. Check the path properly using the PWD command. If possible share your code here.

This path I have provided by checking pwd path only. if the same path I am passing in aws cli then it is working perfectly.

Hi,

You are able to access your files from AWS CLI. It means the files are present in your local system not in EC2 instance. I suggest you run your commands in the EC2 instance and paste the screenshot here.
