Please let me know where i am doing wrong. Both the source and destination folders are in same server

What I have tried:

$ComputerName = "ServerName"
$DriveLetter = "D"
$CreateFolderPath = "Log_Backup_$((Get-Date).ToString('yyyy-MM-dd'))"

$SrcPath = \\$ComputerName\$DriveLetter$\BMCSoftware\BMCPortalKit\webserver\tools\apache-openssl\logs
$DestPath = \\$ComputerName\$DriveLetter$\Log_Backup_$((Get-Date).ToString('yyyy-MM-dd'))
New-Item -Path \\$ComputerName\$DriveLetter$\$Path -type directory -Force // Creating folder
Copy-Item -Recurse -Filter *.* -path $SrcPath -destination $DestPath -Force
