How to set PITR for all databases in a Azure Sql Database Elastic Pool?

问题

I think I'm running into version issues because the cmdlet I want seems to only be available in AzureRM.Sql module version 4.7.0-preview.

I want to set the PITR retention policy for many databases in an elastic pool to 35 days. By default my vCore pool has a retention policy of 7 days which is not enough. I have hundreds of databases so need to set them all with PowerShell.

If I get the list of databases to update with Get-AzureRmSqlElasticPoolDatabase and then try to run Set-AzureRmSqlDatabaseBackupShortTermRetentionPolicy I get this error when running the latter:

import-module : The following error occurred while loading the extended type data file: Error in TypeData "Microsoft.Azure.Commands.Sql.Replication.Model.AzureSqlDatabaseCopyModel": The member DefaultDisplayPropertySet is already present.
Error in TypeData "Microsoft.Azure.Commands.Sql.Replication.Model.AzureReplicationLinkModel": The member DefaultDisplayPropertySet is already present.

    + CategoryInfo          : InvalidOperation: (:) [Import-Module], RuntimeException
    + FullyQualifiedErrorId : FormatXmlUpdateException,Microsoft.PowerShell.Commands.ImportModuleCommand

Things I've tried

I've tried removing the module and re-importing it. Same error. I've tried importing the required version of the module and getting the database list with the first command but I then get this error:

Get-AzureRmSqlElasticPoolDatabase : The 'Get-AzureRmSqlElasticPoolDatabase' command was found in the module 'AzureRM.Sql', but the module could not be loaded. For more information, run 'Import-Module AzureRM.Sql'.

    + CategoryInfo          : ObjectNotFound: (Get-AzureRmSqlElasticPoolDatabase:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CouldNotAutoloadMatchingModule

If I import the AzureRm module with import-module azurerm.sql I get this error:

import-module : The following error occurred while loading the extended type data file: Error in TypeData "Microsoft.Azure.Commands.Sql.Replication.Model.AzureSqlDatabaseCopyModel": The member DefaultDisplayPropertySet is already present.

Any ideas on how to get this working?

回答1:

You could try to install 4.11.4-preview version of AzureRM.Sql module, refer to this link, use Install-Module -Name AzureRM.Sql -RequiredVersion 4.11.4-preview -AllowPrerelease in the powershell administrator environment.

After installing it, no need to import module, you could excute the command straightly. If you want to check the module if installs successfully, navigate to C:\Program Files\WindowsPowerShell\Modules\AzureRM.Sql, you will find a 4.11.4 folder.

Then try the sample command to set PITR for all databases in a Elastic Pool , it works fine on my side.(You could execute Get-Help Set-AzureRmSqlDatabaseBackupShortTermRetentionPolicy to get the usage of the command)

$dbs = Get-AzureRmSqlElasticPoolDatabase -ResourceGroupName "joywebapp" -ServerName "joydb" -ElasticPoolName "joyelastic"
foreach($db in $dbs){
    Set-AzureRmSqlDatabaseBackupShortTermRetentionPolicy -ResourceGroupName $db.ResourceGroupName -ServerName $db.ServerName -DatabaseName $db.DatabaseName -RetentionDays 35
}
