Restoring a SAP HANA database backup includes initiating a connection session with the SnapCenter Server, listing the backups and retrieving backup information, and restoring a backup.

Before you begin

You must have prepared the PowerShell environment to execute the PowerShell cmdlets.

Steps

Initiate a connection session with the SnapCenter Server for a specified user by using the Open-SmConnection cmdlet.
```
Open-smconnection  -SMSbaseurl  https:\\snapctr.demo.fujitsu.com:8146/
```

Identify the backup that you want to restore by using the Get-SmBackup and Get-SmBackupReport cmdlets.

This example shows that there are two backups available for the restore:

 PS C:\> Get-SmBackup

        BackupId    BackupName                    BackupTime            BackupType
        --------    ----------                    ----------            ----------
         1          Payroll Dataset_vise-f6_08... 8/4/2015 11:02:32 AM  Full Backup
         2          Payroll Dataset_vise-f6_08... 8/4/2015 11:23:17 AM

This example displays detailed information about the backup from January 29th 2015 to February 3rd, 2015:

PS C:\> Get-SmBackupReport -FromDateTime "1/29/2015" -ToDateTime "2/3/2015"

SmBackupId           : 113
   SmJobId              : 2032
   StartDateTime        : 2/2/2015 6:57:03 AM
   EndDateTime          : 2/2/2015 6:57:11 AM
   Duration             : 00:00:07.3060000
   CreatedDateTime      : 2/2/2015 6:57:23 AM

   ProtectionGroupName  : Clone
   SmProtectionGroupId  : 34
   PolicyName           : Vault
   SmPolicyId           : 18
   BackupName           : Clone_SCSPR0019366001_02-02-2015_06.57.08
   VerificationStatus   : NotVerified

   SmBackupId           : 114
   SmJobId              : 2183
   StartDateTime        : 2/2/2015 1:02:41 PM
   EndDateTime          : 2/2/2015 1:02:38 PM
   Duration             : -00:00:03.2300000
   CreatedDateTime      : 2/2/2015 1:02:53 PM
   Status               : Completed
   ProtectionGroupName  : Clone
   SmProtectionGroupId  : 34
   PolicyName           : Vault
   SmPolicyId           : 18
   BackupName           : Clone_SCSPR0019366001_02-02-2015_13.02.45
   VerificationStatus   : NotVerified

Start the recovery process in the HANA studio.

The database is shut down.

Restore data from the backup by using the Restore-SmBackup cmdlet.

AppObjectId is "Host\Plugin\UID", where UID = SID is for single container type resource and UID = MDC\SID is for multiple containers resource. You can get the ResourceID from the Get-smResources cmdlet.

Get-smResources  -HostName cn24.sccore.test.com  -PluginCode HANA

This example shows how to restore the database from the primary storage:

Restore-SmBackup -PluginCode HANA -AppObjectId cn24.sccore.test.com\hana\H10 -BackupId 3

This example shows how to restore the database from the secondary storage:

Restore-SmBackup -PluginCode 'HANA' -AppObjectId cn24.sccore.test.com\hana\H10 -BackupId 399 -Confirm:$false  -Archive @( @{"Primary"="<Primary Vserver>:<PrimaryVolume>";"Secondary"="<Secondary Vserver>:<SecondaryVolume>"})

The backups will be available in HANA studio for recovery.

The information regarding the parameters that can be used with the cmdlet and their descriptions can be obtained by running Get-Help command_name.
