False

GuestCredentials

Specifies credentials for authenticating to the target machine. If these credentials do not work, the cmdlet will use the credentials specified in the backup job.

Consider the following:

  • If you omit this parameter, the cmdlet will use the credentials specified in the SqlCredentials parameter to connect to both Microsoft SQL Server and to the guest OS.
  • If you do not specify SQL credentials, the cmdlet will use the current account credentials.

Accepts the PSCredential object. To get this object, run the Get-Credential cmdlet.

False

Named

Named

False

RecoveryState

Specifies the restore scenario.

  • Recovery — use this option to leave a Microsoft SQL database in the ready to use state. With this option, you will not be able to restore additional transaction logs.
  • NoRecovery — use this option to leave a Microsoft SQL database in the non-operational state and to avoid rolling back uncommitted transactions. Use this option to restore transaction logs that are backed up with a third-party tool.
  • StandBy — use this option to leave the Microsoft SQL database in the read-only mode. It allows you to undo uncommitted transactions. The undo actions are saved in a standby file so that the recovery effects can be reversed.

Default: Recovery

RestoreMode

False

Named

False

StandbyFilePath

For the StandBy parameter.

Specifies a location for the standby file with the uncommitted transactions.

String

False

Named

False

Examples

Restore-VESQLDatabaseExample 1. Restoring Microsoft SQL Server Database to Original Location

This example shows how to restore a Microsoft SQL database to the original location. The restore operation will run with the following settings:

  • The cmdlet will use the credentials of the user that is running the PowerShell session.
  • If these credentials do not work, the cmdlet will use the backup job credentials to connect to the guest OS and to Microsoft SQL Server.

 

$session = Get-VESQLRestoreSession

$database = Get-VESQLDatabase -Session $session[0] -Name "SQLDatabase"

Restore-VESQLDatabase -Database $database

Perform the following steps:

  1. Run the Get-VESQLRestoreSession cmdlet. Save the result to the $session variable.

The cmdlet will return an array of restore sessions. Note the ordinal number of the necessary restore session. In our example, it is the first restore session in the array.

  1. Run the Get-VESQLDatabase cmdlet. Set the $session variable as the Session parameter value and select the necessary restore session. Specify the Name parameter value. Save the result to the $database variable.
  2. Run the Restore-VESQLDatabase cmdlet. Set the $database variable as the Database parameter value.
