SAP database objects supported by advanced backup methods
The brbackup command and Oracle RMAN control the kinds of database objects that can be backed up using Snapshot Client backup methods. Oracle allows proxy copy backups of databases, tablespaces, and data files.
For profile and configuration files, the NetBackup for SAP backint command performs standard backups directly to the configured storage unit. NetBackup for SAP uses advanced methods only when it moves Oracle data files.
The following is additional information on special file types for UNIX or Linux:
Symbolic links and raw data files. NetBackup for SAP with Snapshot Client backs up and restores the data files that consist of symbolic links and regular files. NetBackup for SAP backs up and restores both the symbolic link and the file. If you select , the symbolic link must reside on the same file system as the data file. When you use instant recovery, if the symbolic link resides on a different file system than the data file it points to, the restore fails.
NetBackup for SAP with Snapshot Client backs up and restores the data.
Files that are created on raw partitions:
Quick I/O data files. NetBackup for SAP with Snapshot Client backs up and restores Quick I/O Oracle data files. A Quick I/O file consists of two components: A hidden file with space allocated for it and a link that point to the Quick I/O interface of the hidden file.
On the backup, NetBackup for SAP with Snapshot Client follows the symbolic link and backs up both components of the Quick I/O file: The symbolic link and the hidden file.
On the restore, NetBackup for SAP with Snapshot Client restores both components from the backup image. If one or both of the components are missing, NetBackup for SAP with Snapshot Client creates the missing component(s).
