Performing SAP restores of volumes and file systems using block-level restore (Unix/Linux) or Fast File Resync (Windows)
This method requires the original primary data file to be present at the time of restore. The brrestore command deletes database files before restores to avoid permission problems. You can suppress this action by setting an environment variable. For example, use: BR_NFD = 1 or brrestore command parameter -NFD.
