I need help with PowerShell command " Get-NcSnapshot -SnapName Veeam | Set-NcSnapshot -Snapmirror"

powershelbeginner — Tue, 04 Mar 2025 20:10:39 GMT

I have a powershell script that has been working well for the past 4 yrs., Recently I migrated the script to a new environment and it started giving errors

what the script does is to login the source filer A, change the snapshots' snapmirror labels to "daily" then snapvault these snapshots to the destination filer B

When i run it, it seems the script is able to login both filer A and filer B, and replicate the snapshots over. It failed on getting the snapshots, and gave me 400 errors are below

Hi there,

From my experience, PSTK throws error when it queries the controller
Get-NcSnapshot : The remote server returned an error: (400) Bad Request.

I can recreate the error on my laptop too.

PS C:\Users\user\Scripts> Read-NcDirectory -Path /vol/mystore1 |where-object {$_.Name -Notmatch "\."} |measure-object
Read-NcDirectory: The remote server returned an error: (400) Bad Request.

Tried again - it works

PS C:\Users\user\Scripts> Read-NcDirectory -Path /vol/mystore1 |where-object {$_.Name -Notmatch "\."} |measure-object

Count : 47
Average :
Sum :
Maximum :
Minimum :
StandardDeviation :
Property :

So, what you can do is, trap that "Bad Request" and retry until no "Bad Request" error then continue. I think it is flow in PSTK 9.15.1.2.xxxx

Hey Sanaman

Very appreciate your response.

I got your instructions, could you please tell the commands as I have no idea on how t trap the "Bad Request"

Thanks so much

Unfortunately, I can't teach you PowerShell to trap the error. Basic thing is your script is calling Get-NcSnapshot somewhere and you need to trap the output first time and try again. Something like this:

$Variable = Get-NcSnapshot <your_volume_name>
if ($Variable -Match "Bad Request") {
Write-Host "Trying again"
Get-NcSnapshot <your_volume_name>
}

It seems that you are using PowerShell Toolkit version 9.11.1 or higher. In these versions, the volume parameter is required, so you will need to specify the volume name as well.

Use the command as follows:

Get-NcSnapshot -SnapName <snapshot-name> -Volume <volume-name> | Set-NcSnapshot -Snapmirror ...
