Hello @Venkata satyanarayana Machari veera (CIS) ,
Welcome to Microsoft QnA.
You can use the below common Powershell cmdlet to identify all the snapshots in your subscription which are older than 30 days.
Get-AzSnapshot |
>> Where-Object {$_.TimeCreated -lt (Get-Date).AddDays(-30)} |
>> Select-Object name, TimeCreated, ResourceGroupName
Hope this helps. Please feel free to reach back if you have any questions. Thanks :)
