Symptoms

Customer is running the following RMAN backup script, as shown here.

backup section size 2G incremental level 1 for recover of copy datafilecopy format '< backup_path>/%b' with tag 'img_copy' datafile 1,2,3,4,5;
backup section size 2G incremental level 1 for recover of copy datafilecopy
format '<backup_path>/%b' with tag 'img_copy' datafile
1,
...

However, RMAN ignores the SECTION SIZE clause and thus does not backup the datafiles in parallel.

Changes

 No changes, wanting to parallelize the datafile copy taken by RMAN's merged incremental backup strategy.
