Step 9. Following the above steps, create a brand new Runbook for deleting outdated snapshots and replica the beneath code. The beneath code will test for older snapshots and delete them.

Join-AzAccount -Id

$resourceGroupName = "snapshottest"
$accountName = "snapshotnfstest"
$shareName = "testfileshare"

#$snapshotLifetimeInDays = "15"
$snapshotLifetimeInMinutes = "5"
$whatIf = $false

$CurrentDateTime = (Get-Date).ToUniversalTime()
#$DateTimeThreshold = $CurrentDateTime.AddDays(-$snapshotLifetimeInDays)
$DateTimeThreshold = $CurrentDateTime.AddMinutes(-$snapshotLifetimeInMinutes)

Write-Host "Querying all snapshots for share '$shareName'"

$snapshotList = (Get-AzRmStorageShare -ResourceGroupName $resourcegroupname -StorageAccountName $accountName -IncludeSnapshot) | The place-Object { $_.Identify -eq $shareName -and $_.snapshotTime -ne $null }

Write-Output $snapshotList

Write-Output "Present date/time is $CurrentDateTime. Eradicating share snapshots older than '$DateTimeThreshold'"

foreach ($snapshot in $snapshotList) {
    if ($snapshot.SnapshotTime -lt $DateTimeThreshold) {
        Write-Output "Eradicating snapshot '$($snapshot.snapshotTime)' of share '$($snapshot.Identify)'"
        if ($whatIf -ne $true) {
            Take away-AzRmStorageShare -ResourceGroupName $resourcegroupname -StorageAccountName $accountName -Identify $snapshot.Identify -snapshotTime $snapshot.snapshotTime -Drive
        }
        else {
            Write-Output "Retaining current snapshot '$($snapshot.snapshotTime)' of share '$($snapshot.Identify)'"
        }
    }    
}
