Headline
Tranzman UI provides a user friendly interface to browse the migrated images and restore data to the mounted NFS/CIFS share as per the Devices page. Click on Actions on sidebar and Select Restore. You should see the restore page with three sections.
- Images section for selecting the images to restore data from.
- Image Content section for browsing through the data in the selected images and select the contents you want to restore.
- Selection section for reviewing selected content for restore and run the restore for the selected.
So follow the below steps to perform the restore of SAP HANA Backups.
Step 1
Select the Policy, Client, Backup Time From, Backup Time To and hit on 
and you should see all the images in the time interval selected.
 |
Note: Our SAP HANA Server is saphana2.localdomain. We are restoring a full backup from 2020-09-29. |
Step 2
Select the image you want to restore the data from Images section.Browse through the data in that Image in Image Content section and select it to restore.
|
Note: The way SAP HANA does backups by default is it splits its data files during backup and create different images/sessions. Similarly when you will select an image for restore, all the images which should be part of the group will be selected automatically. |
Step 3
From the Selection section on the webpage , select the Destination for the restore. This refers to the NFS/CIFS share mounted for restoring data under Devices .Then enter the
path (name of folder) where you want the data to be restored and click on 
. This should trigger the restore and the Restore button should be greyed out.
Step 4
Once the Restore job is triggered successfully , you would see new jobs in Tasks under Views->Tasks on the sidebar. Additionaly there is another section under Views->Tasks named Restore logs (shown below) where user can check the restore status , and also re-run the restore with or without modifications for restore paths.
Step 5
When the restore is completed, copy the restored files from the share to the SAP HANA Server. Then login to the SAP HANA Studio.
|
Note: For this restore we have the below files restored by the Tranzman Appliance.Same has been copied to our SAP HANA
server under |

Step 6
Login to the SAP HANA Studio and connect to the SRL instance.
|
Note: SRL is the instance we are restoring the files to. It is quite evident from the restore Selected path too. Also if you prefer to restore the files using command line , you can always refer to the SAP Help Portal. However it is strongly recommended that you use SAP HANA studio. |
