You may occasionally need to back up individual data files. For example, when troubleshooting issues with backups, it’s often helpful to attempt to successfully backup one data file. You can specify data files by file name or by file number, as follows:
RMAN> backup datafile '/u01/dbfile/O12C/system01.dbf';In this example, file numbers are specified:
RMAN> backup datafile 1,4;Here are some other examples of backing up data files, using various features:
RMAN> backup as copy datafile 4;
RMAN> backup incremental level 1 datafile 4;
Tip Use the RMAN REPORT SCHEMA command to list tablespace, data file name, and data file number information.
