Greetings -
I wrote below PS to upload my backup files from local machine to AWS S3 storage, and it works. However, the process time is about 3 hours to upload 430 GB of backup files. The code goes through the loop to read each file, upload it, and then load the next file and so on. Can you please guide me on how to handle parallel data upload in PowerShell? I did some search, but I could not find a good answer, thank you.
$s3Bucket = 'TESTBUCKET'
$backupPath = 'E:\BKUP\FULL\'
$region = 'us-east-1'
$accessKey = '123'
$secretKey = '123'
$results = Get-ChildItem -Path $backupPath -Recurse -Include "*.bak" -file
foreach ($path in $results)
{
Write-Host $path
$filename = [System.IO.Path]::GetFileName($path)
Write-S3Object -BucketName $s3Bucket -File $path -Key /DestPath/subfolder/$filename -Region $region -AccessKey $accessKey -SecretKey $secretKey
}

Presumably you did a Google search for 'multithreading in powershell' or similar? There are plenty of results ... what did you try?

Phil -
I indeed searched before asking the question since most of the times there are examples/articles out there, I only found others mentioning the use of Invoke-Command but couldn't find a clear example showing how to implement it.
I tested with using cloudberry tool which saved 2 hours of process time, however I rather to use PS script and that is why I posted the question hoping to get an answer. Thank you.

Phil - Thank you for the link, I will look into it. Meantime please let me know if there are any other known simple ways to do it.

Maybe I'm misreading that but it looks like the proverbial keys to the city are in that code I just love it when people store keys and passwords in clear text. It keeps hackers from damaging other things trying to hack out what they are and saves a whole lot of CPU in the process. :sick: :Whistling:

Use SSIS? Parallelism is easy to implement there ... if you know SSIS 😉

I have been wanting to update this post to include the script I wrote after I posted the question, so here I am to updating it:
First, Jeff - Thank you for your comment, I now use the profile for calling the key and secrete key, see below. Also Phil - I appreciate your guidance, I use script block and
Start-ThreadJob to run the Write-S3Object command for copying the files. With this script, I am able to upload 12 files a little over 500 GB total size in less than 2 hrs.
Script:
Set-AWSCredentials -ProfileName S3_BKUPUpload
$logPath="C:\S3_UploadLog\UploadFull_ScriptBlockMain.log";
if (!(Test-Path $logPath))
{Write-Verbose "Creating $logPath."
$NewLogFile = New-Item $logPath -Force -ItemType File
}
Write-Output "$(Get-Date -Format "yyyy-MM-dd HH:mm:ss") INFO: Script Started" | Out-File -FilePath $logPath -Append
$cmd = {
param($a, $b)
[string] $datestamp = $((Get-Date)).ToString("yyyyMMddHHmmss_fff")
$logPath="C:\S3_UploadLog\UploadFULL_Thread_"+ $datestamp + ".log";
try{ if (!(Test-Path $logPath))
{
Write-Verbose "Creating $logPath."
$NewLogFile = New-Item $logPath -Force -ItemType File
