Note.png 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.

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 Restore.JPG. 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.
