Copy Files on Same Directory using Powershell - powershell

Question

I am trying to write powershell Script which will create backupfolder on same Path where Application exist and need to copy the folders & files into backupfolder before deploying. Below are the command was using to perform but am getting error
$Source = "C:\XYZ"
$BackupFolder = New-Item -ItemType Directory -Force -Path $source_$(Get-Date)
Copy-Item -Path $Source\* $BackupFolder -Force
Error: Cannot copy item C:\XYZ\Backup_18-02-2017 on to itself

Answer 1

Try:
Copy-Item $Source\* $BackupFolder -Exclude $BackupFolder
That will eliminate the folder that you are copying into as a source that is being copied from.

Answer 2

Variables can contain underscores. The following works and displays the string "asdf"
$a_ = "adsf"; $a_
Your New-Item cmdlet call should have failed since $source_ is not a variable and would return null. This is default behavior for PowerShell. When I run your code as is I get the following:
New-Item : Cannot find drive. A drive with the name '02/18/2017 22' does not exist.At line:1 char:1
+ New-Item -ItemType Directory -Force -Path "$source_$(Get-Date)" -what ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (02/18/2017 22:String) [New-Item], DriveNotFoundException
+ FullyQualifiedErrorId : DriveNotFound,Microsoft.PowerShell.Commands.NewItemCommand
So I would have expected your folder variable to be null. wOxxOm brings this up in comment as well
Several options to address what I am sure is the partial source of your issue.
$BackupFolder = New-Item -ItemType Directory -Force -Path "$source`_$(Get-Date)"
$BackupFolder = New-Item -ItemType Directory -Force -Path "$($source)_$(Get-Date)"
$BackupFolder = New-Item -ItemType Directory -Force -Path ("{0}_{1} -f "$source, Get-Date)
You will still have to try and exclude this folder from the copy as well like Keith Hill's answer is telling you
Copy-Item $Source\* $BackupFolder -Exclude $BackupFolder

Answer 3

try Something like this
$Source = "C:\XYZ"
$Destination="{0}{1:yyyyMMdd}" -f $source, (Get-Date)
New-Item -ItemType Directory -Force -Path $Destination
Copy-Item -Path $Source\* $Destination -Recurse -Force

If I understand the question correctly. You want to take "C:\XYZ" and backup into the same directory called "C:\XYZ\backup_$DATE". What you will actually do is create a loop that will break once it reaches the max 248 characters. If we use the -exclude option then we can exclude the backup directory "C:\XYZ\backup_$DATE".
This function will do the trick and also gives you error handling.
Function Get-CopyDirectory{
#####################
# Dynamic Variables #
#####################
$Date = Get-Date -format ddMM-yyyy
$Exclude="Backup*"
####################
# Static Variables #
####################
$AppPath = "F:\Test\"
$BackupPath = "$AppPath\BACKUP_$Date\"
if (Test-Path $BackupPath) {
Write-Host "Backup Exist" -f Cyan
}
else
{
Copy-Item "$AppPath\*" $BackupPath -Exclude $Exclude -recurse -verbose
}
}
CLS
Get-CopyDirectory
