How to set the retain period of Files Share snapshot with scheduler by Azure Automation? - azure

Question

I want to set the retention period of Files Share snapshot with scheduler by Azure Automation. 1, May I set the schedule of creating and deleting the snapshot at one runbook. (like create one snapshot at today and delete it after one month). 2, I want to get some snapshots by every day, week and month, can I decide the retain time. (Like keep the daily snapshot 15 days, the weekly snapshot 35days, and the Monthly snapshot 13months).
3, If it is so difficult, may I decide the snapshots that I want to delete, like the previous 10. If you know something about that, please write some comments below, thanks so much.

Answer 1

Some information for you to refer.
Try the command below to create snapshot, for its operating frequency, you could create a schedule for the runbook.
$connectionName = "AzureRunAsConnection"
try
{
# Get the connection "AzureRunAsConnection "
$servicePrincipalConnection=Get-AutomationConnection -Name $connectionName
"Logging in to Azure..."
Add-AzureRmAccount `
-ServicePrincipal `
-TenantId $servicePrincipalConnection.TenantId `
-ApplicationId $servicePrincipalConnection.ApplicationId `
-CertificateThumbprint $servicePrincipalConnection.CertificateThumbprint
}
catch {
if (!$servicePrincipalConnection)
{
$ErrorMessage = "Connection $connectionName not found."
throw $ErrorMessage
} else{
Write-Error -Message $_.Exception
throw $_.Exception
}
}
$SAResourceGroupName="joywebapp"
$StorageAccountName="joystoragev2"
$StorageAccountKey = (Get-AzureRmStorageAccountKey -ResourceGroupName $SAResourceGroupName -AccountName $StorageAccountName).Value[1]
$context=New-AzureStorageContext -StorageAccountName $StorageAccountName -StorageAccountKey $StorageAccountKey
$share = Get-AzureStorageShare -Context $context -Name "111"
$snapshot = $share.Snapshot()
Delete the snapshots created before one month:
$allsnapshots = Get-AzureStorageShare -Context $context | Where-Object { $_.Name -eq "111" -and $_.IsSnapshot -eq $true }
foreach($snapshot in $allsnapshots){
if($snapshot.SnapshotTime -lt (get-date).AddMonths(-1)){
$snapshot.Delete()
}
}
