Copy-Item for copy files from local to remove server using credentials

问题

I am trying to copy some files and folder from my local machine to a remote server:

Copy-Item .\copy_test.txt -destination "\\serverip\c$\backups\"

but I'm getting an error:

Copy-Item : Logon failure: unknown user name or bad password.
At line:1 char:10
+ Copy-Item <<<<  .\copy_test.txt -destination "\\serverip\c$\backups\" -verbose
    + CategoryInfo          : NotSpecified: (:) [Copy-Item], IOException
    + FullyQualifiedErrorId : System.IO.IOException,Microsoft.PowerShell.Commands.CopyItemCommand

I was trying using credentials but this command does not allow -Credential argument. I was searching a lot and in every example the command is pretty easy just executing the Copy-Item $source -destination $destination and I wonder why is so hard in my workstation.

Creating New PSDrive

I tried to create a New-PSDrive but it didn't work.

$creds = New-Object -TypeName System.Management.Automation.PSCredential -argumentlist $username, $password

New-PSDrive -Name X -PSProvider FileSystem -Root '\\$serverip\c$' -Credential $creds -Persist
Copy-Item '.\copy_test.txt' -Destination 'X:\backups'
Remove-PSDrive -Name X

It is the error message:

PS C:\Users\Administrator\Desktop> .\copyfiles.ps1
New-PSDrive : The network path was not found

My servers

My server are windows instances in AWS. I have the right permission because I am able to run other command like Invoke-Command in order to inspect some services into the remote server.

If credentials are required for access to a remote share you need to map it to a (PS)drive before you can use it with other cmdlets.

$cred = Get-Credential
New-PSDrive -Name X -PSProvider FileSystem -Root "\\$serverip\c$" -Credential $cred -Persist
Copy-Item '.\copy_test.txt' -Destination 'X:\backups'
Remove-PSDrive -Name X

I found the solution. I was using PowerShell version 4.0 and then upgrade my version to 5.0

In previous version the Copy-Item doesn't allow credentials. Now is possible to copy files through the sessions between servers:

$deploy_dest = "C:\backup"
$username = "$server\Administrator"
$password =  Get-Content C:\mypassword.txt | ConvertTo-SecureString -AsPlainText -Force

$creds = new-object -typename System.Management.Automation.PSCredential -argumentlist $username, $password

$session = New-PSSession -ComputerName $server -Credential $creds

Copy-Item -Path .\copy_test.txt -Destination -ToSession $session
