InstanceName	For restore to another location. Specifies the name of a target instance. The cmdlet will restore a Microsoft SQL database to the specified target instance.	False	Named	False	False
Port	Specifies a port number. The cmdlet will use this port to connect to the target Microsoft SQL server.	False	Named	False	False
SqlCredentials	Specifies credentials to authenticate against a Microsoft SQL server. NOTE: If you do not specify SQL credentials, the cmdlet will use current account credentials. The cmdlet will use credentials, specified in the backup job in the following scenarios: If current account credentials do not work If you omit the Server parameter	False	Named	False	False
UseSQLAuthentication	Indicates that the cmdlet will use the SQL authentication to connect to the target Microsoft SQL server. NOTE: If you omit this parameter, the cmdlet will use credentials specified in the SqlCredentials parameter to connect to both the Microsoft SQL server and to the guest OS.	False	Named	False	False
GuestCredentials	Specifies credentials to authenticate against the target server. In case the specified credentials do not work, the cmdlet will use credentials, specified in the backup job. NOTE: If you omit this parameter, the cmdlet will use credentials specified in the SqlCredentials parameter or current account credentials to connect to both the Microsoft SQL server and to the guest OS.	False	Named	False	False
ToPointInTime	Specifies the point in time within a restore interval of a Microsoft SQL database. The cmdlet will restore the database to the state of the specified point in time.	False	Named	False	False
Availability GroupName	Specifies the name of the AlwaysOn availability group. The cmdlet will add a Microsoft SQL database to the specified group.	False	Named	False	False
TargetFolder	For restore Microsoft SQL database files to one location. Specifies the folder. The cmdlet will restore all database files to that folder. NOTE: This parameter is not available if you use the TargetPath parameter.	False	Named	False	False
File	Specifies an array of filenames for Microsoft SQL databases. Accepts the VESQLDatabaseFile[] type.	False	Named	False	False
TargetPath	Specifies a target path array. The cmdlet will restore Microsoft SQL database files to locations, specified in the target path array. NOTE: For every Microsoft SQL database file, you must assign the specific file path. This parameter is not available if you use the TargetFolder parameter.	False	Named	False	False
Force	Indicates that the cmdlet will overwrite an existing Microsoft SQL database with a Microsoft SQL database from a backup. NOTE: The cmdlet will show no prompt before executing the command.	False	Named	False	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 not to roll back uncommitted transactions. Use this option to restore transaction logs that are backed up with the third-party tool. StandBy - use this option to leave a 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.	False	Named	False	False
StandbyFilePath	For the StandBy parameter. Specifies a location for the standby file with the uncommitted transactions.	False	Named	False	False

This cmdlet supports Microsoft PowerShell common parameters. For more information about common parameters, see http://go.microsoft.com/fwlink/p/?LinkID=113216.

Return Type

Example 1

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

The cmdlet will use credentials of the user that is running the PowerShell session.
In case these credentials do not work, the cmdlet will use the backup job credentials to connect to Windows OS and to a Microsoft SQL server.

You must perform the following steps:

Run Get-VESQLRestoreSession to get a restore session for a Microsoft SQL database. Save the result to the $session variable.
Run Get-VESQLDatabase with the $session variable to get the Microsoft SQL database that you want to restore. Save the result to the $database variable.
Run Restore-VESQLDatabase with the $database variable.

PS C:\PS> $session = Get-VESQLRestoreSession

PS C:\PS> $database = Get-VESQLDatabase -Session $session[0] -Name "SQLDatabase"

PS C:\PS> Restore-VESQLDatabase -Database $database

Example 2

This example shows how to restore a Microsoft SQL database to the specific folder. To authenticate against a Microsoft SQL server and Windows OS, the cmdlet will use the same type of credentials.

Run Get-VESQLRestoreSession to get a restore session for a Microsoft SQL database. Save the result to the $session variable.
Run Get-VESQLDatabase with the $session variable to get the Microsoft SQL database that you want to restore. Save the result to the $database variable.
Run Get-Credential to create a credential object that you want to use for authenticating with the Microsoft SQL server and Windows OS. Save the result to the $creds variable.
Run Restore-VESQLDatabase with the $database variable. Use the TargetFolder parameter to specify the restore location.

PS C:\PS> $session = Get-VESQLRestoreSession

PS C:\PS> $database = Get-VESQLDatabase -Session $session[0] -Name "SQLDatabase"

PS C:\PS> $creds = Get-Credential

PS C:\PS> Restore-VESQLDatabase -Database $database -ServerName "SQLServer" -TargetFolder "C:\SQL\Restore" -SqlCredentials $creds

Example 3

This example shows how to restore Microsoft SQL database files to the specified array. The restore session will run with the following options:

The cmdlet will restore the File1.mdf file to the C:\SQLDBfile1\new_file.mdf location.
The cmdlet will restore the File2.ldf file to the C:\SQLDBfile2\new_file.ldf location.
The cmdlet will use different types of credentials to authenticate with a Microsoft SQL server and Windows OS.

You must perform the following steps:

Run Get-VESQLRestoreSession to get a restore session for a Microsoft SQL database. Save the result to the $session variable.
Run Get-VESQLDatabase with the $session variable to get the Microsoft SQL database that you want to restore. Save the result to the $database variable.
Run Get-VESQLDatabaseFile to get an array of Microsoft SQL database files that you want to restore. Save the result to the $files variable.
Use the $files variable to get details about Microsoft SQL database files.
Specify an array of the paths for every database file that you want to restore. Save the result to the $path variable.
Run Get-Credential to create a credential object that you want to use for authenticating with the SQL server. Save the result to the $sqlcreds variable.
Run Get-Credential to create a credential object that you want to use for authenticating with Windows OS. Save the result to the $oscreds variable.
Run Restore-VESQLDatabase with the variables obtained beforehand.

PS C:\PS> $session = Get-VESQLRestoreSession

PS C:\PS> $database = Get-VESQLDatabase -Session $session[0] -Name "SQLDatabase"

PS C:\PS> $files = Get-VESQLDatabaseFile -Database $database

PS C:\PS> $files

Path Type

---- ----

C:\Program Files\File1.mdf Primary

C:\Program Files\File2.ldf Secondary

PS C:\PS> $path = @("C:\SQLDBfile1\new_file.mdf","C:\SQLDBfile2\new_file.ldf")

PS C:\PS> $sqlcreds = Get-Credential

PS C:\PS> $oscreds = Get-Credential

PS C:\PS> Restore-VESQLDatabase -Database $database -ServerName "SQLServer" -File $files -TargetPath $path -SqlCredentials $sqlcreds -GuestCredential $oscreds -UseSqlAuthentication

Example 4

This example shows how to restore Microsoft SQL database files to the latest restore point.

Run Get-VESQLRestoreSession to get a restore session for a Microsoft SQL database. Save the result to the $session variable.
Run Get-VESQLDatabase with the $session variable to get the Microsoft SQL database that you want to restore. Save the result to the $database variable.
Run Get-VESQLDatabaseRestoreInterval with the $database variable to get details about an available restore period of the Microsoft SQL database. Save the result to the $restoreinterval variable.
Run Restore-VESQLDatabase with the $database variable. Specify the following options:

Use the TargetFolder parameter to specify the restore location
Use the $restoreinterval variable with the ToUtc property for the ToPointInTime parameter to specify the latest restore point of the database.

PS C:\PS> $session = Get-VESQLRestoreSession
