6.6 Intermediate Storage Requirements

The NFS or shared storage between the source and the target database should have sufficient storage to hold all the RMAN backups and Data Pump dump files. You can specify the compression for the RMAN backups which should result in space reduction, however, conservatively, ensure that the space should be at-least as large as the size of the source database. You can specify the RMAN compression using the RMANSETTINGS_COMPRESSIONALGORITHM parameter.
