Get latest snapshot

seffysefix — Thu, 05 Jun 2025 05:38:57 GMT

Hi all,

I need help to create a PS script that runs on multiple filers and gets the latest snapshots on the volumes.

Then, email this information.

Can anyone help?

Thanks

Hey Seffy,

Can you try this

save the below to a .ps1 file, make sure that you enter your controller names in filernames.txt, the current script asks the user for credentials everytime it reads a new controller name in filernames.txt

$filerlist = Get-Content "c:\filernames.txt"
$volinfoarraysnap=@()
foreach ($filer in $filerlist)
{
Connect-NaController -Name $filer -Credential (Get-credential)
$voldetails = Get-NaVol
foreach ($vol in $voldetails)
{
$snapshotdetails = Get-Nasnapshot -TargetName $vol | Sort-Object -Descending created | select -First 1
        $volinformation = New-Object -TypeName psobject -Property @{
            'VolumeName'    = $vol.Name;
            'VolumeLatestSnapshotName' = $snapshotdetails.Name;
            'VolumeLatestSnapshotCreatedDate' = $snapshotdetails.created;
            'VolumeLatestSnapshotTotal(MB)' = ($snapshotdetails.Total)/1mb
            'VolumeLatestSnapshotCumulative(MB)' = ($snapshotdetails.CumulativeTotal)/1mb
           }
           $volinformation
            $volinfoarraysnap += $volinformation
            }
}
$volinfoarraysnap | Export-Csv "c:\volsnapinfo.csv"

If you have a same user name and password for all your controllers you can use the below scriptlet in your code.

$ControllerPassword = ConvertTo-SecureString -String 'netapp1!' -AsPlainText -force

$credential = New-Object System.Management.Automation.PsCredential("vsadmin",$ControllerPassword)

$test = Connect-NaController -Name $control -Credential $credential

Hi Vinith,

Thank you for your reply.

the script works great, but is it possible to have it run on the volumes and show only volumes that haven't been snapshots in the last 48 hours?

What i mean is: have it run on all filers then get all volumes snapshots and if a volume doesn't have a snapshot in the last 48 hours, show in CSV.

Thanks,

can you replace the variable $snapshotdetails with the below and see if it helps.

$snapshotdetails = Get-Nasnapshot -TargetName $vol | Sort-Object -Descending created | select name,created,total,cumulativetotal,@{Name="AccessTime"; Expression = {([datetime]"1/1/1970").AddSeconds($_.AccessTime).ToLocalTime()}} | where-object {$_.AccessTime -lt (Get-Date).Addhours(-48)} | select -First 1

you can also use (get-date).Adddays(-2) to find snapshots older than two days (48 hours)

Hi Vihith,

tried it and the report comes back empty.

What i want to achieve is the report to shows only volumes with snapshot older then 48 hours and not show volumes with newer snap shots.

What I mean is if the latest snap shot is older than 48 hours, show it on the CSV.

thanks
