Powershell脚本在Windows 2008 R2上运行良好，但在Windows 2012 R2上不执行任何操作

Question

I am new to Powershell and I am not sure what to do in regards to the following issue that I am experiencing.

I have the following script that I use to copy the SQL BAK files from my server to my NAS. I consider this a safety measure to make sure that I have a copy of the SQL BAK file outside of my server. The way this script works is very simple. Simply create a SQL job and make sure that "Type:Powershell" is selected, schedule the job and presto change-o! Your BAK files will be copied remotely to your NAS. This script works perfectly fine with Windows 2008 R2 however it does not on Windows 2012.

When I run the SQL job on a Windows 2012 R2 server the job reports that it ran successfully. However when I check the NAS folder no files are copied. I check the logs and the logs reports that the job ran successfully as well.

param
(
[Parameter(Position=0, Mandatory=$true)] [string]$SrcFolder,
[Parameter(Position=1, Mandatory=$true)] [string]$TgtFolder
)

##copy

robocopy $SrcFolder i:\sqlbackups $TgtFolder \as2\sqlbackups\SERVERNAME /e /copy:dat /log+:i:aslog\log.txt

##set exit code
$exit = $lastexitcode -band 24

exit $exit

So I proceeded to put on my troubleshooting hat to determine why this script was failing to copy the files. I first checked to see if I could run the robocopy cmd without the powershell syntax. So I opened a command (admin) shell and I ran the following command like so.

robocopy i:\sqlbackups \as2\sqlbackups\SERVERNAME /e /copy:dat 

As I expected to see this command ran just fine with no issues.

So I then proceeded to the next step and copied the powershell script to my windows powershell ISE. I ran the script and it prompted me with the following.

cmdlet at command pipeline position 1 Supply values for the following parameters: SrcFolder:

I never seen this before and I suspect it has something to do with Windows 2012 R2. I want this script to run without any prompting as it does in Windows 2008 R2. Would anyone know how I can resolve this?

Answer 1

The reason it prompts in ISE is because you have mandatory parameters that you aren't supplying. It would do the same thing on 2008 R2 / PowerShell 2.0.

I don't think this has to do with why it's not working on 2012 R2 though. It sounds like you're trying to run this directly from SQL server, so I have to assume that the 2 different operating systems indicates that you have 2 different instances of SQL server running.

From that, I suspect that the job is being run as 2 different users, and one of them has access to the NAS and the other doesn't.

Some speculation here, but I will update the answer if you have more details.
