Sending files to AWS S3 using Powershell

Amazon has a Powershell module to manage the the principal services available. I’ve been working with EC2, RDS and S3 and I wrote a tip to fast copy data to S3 and I created the function bellow to help to send files to S3.

I’m using the function bellow to send my backups to S3. It’s configured to send all files in the paths passed by parameter

Import-Module AWSPowerShell

function Send-S3Files {

 .SYNOPSIS
 Send the files from a local path to AWS S3
 .DESCRIPTION
 The function will copy all files from a specific path to AWS S3

        foreach($source in $sources) {
            Set-Location $source
            $files = Get-ChildItem '*.*' | Select-Object -Property Name #get all files in the folder

            try {
            if(Test-S3Bucket -BucketName $bucket) {
                foreach($file in $files) {
                    if(!(Get-S3Object -BucketName $bucket -Key $file.Name)) {

    }
}
