This procedure describes how to back up and restore an SAP system on Windows Server 2008 (R2) and higher.
On Windows, a lot of information created during the SAP system installation and operation is stored in databases like the Windows system registry, the user registry, or the Active Directory, when installing in a Windows domain.
Therefore, we recommend that you always back up and restore the complete computer, including the operating system to avoid data or system inconsistency. In addition, the overhead of a full backup of the computer (backup of operating system disk, non-operating system disks, database data files) compared to a database online backup is negligible. During backup, the SAP system can be online.
To be able to back up and restore your SAP system properly in case of emergency, we strongly recommend that you test the backup and restore procedure on a regular basis, to avoid system downtime and data loss.
