Get most recent snapshot

stepheno — Thu, 05 Jun 2025 06:52:43 GMT

Hi All,

I need to set a variable name to that of the most recent snapshot name in a given volume (we're gonna vol clone it). This is likely really basic and easy but I'm just starting to work in powershell and need a hint. Thanks for your replies.

I found one way of doing this, based on their appearance in the snap list and not date/timestamp:

Get-NaSnapshot vol0 | select -expandproperty name -first 1

it works, but still interested in seeing anything anyone else is doing.

I use the following to get the SME snap name.

Get-NaSnapshot volume exchsnap__* | select-object Name -last 1

Just learning powershell myself but hope it helps

Your almost there... To get the last snapshot you just need to add a sort to your pipeline.

$SnapName = Get-NaSnapshot -name vol0 |             
    Sort-Object -Property Created -Descending |             
    Select-Object -ExpandProperty Name -First 1

I see this referenced all of the time...the "Created" property of a snapshot. I've got filers, with ONTAP 7.3.4 thru 8.0.2, and none of them return a "Created" property of a snapshot. I have resorted to sorting by AccessTimeDT. Am I missing something?

Example:

Get-NaVol | Get-NaSnapshot | Get-Member

Hi, Brad. You must be using an older version of the Toolkit. We often use a shortened field name in the tabular views to conserve space, and in a recent release we added a number of alias properties so that you can always refer to fields by the column headers. In your case, Created == AccessTimeDT.

Got it. Updated DataOntap toolkit to 1.5 and I now see the alias. I appreciate the quick response.

Thanks
