RE: Data Pump and compress on the fly in Unix

So how are you guys dealing with this problem then? The mknod allowed us to export huge databases without needing the space up-front. Is there anyone using DATA PUMP for real backups of large datababases? Or just experimenting with it?  

I realise that there's a COMPRESS=METADATA_ONLY option but this is just the METADATA, not the huge amounts of application data that we have in the database.  

Oracle has told us to use datapump in 10g rather than exports. Now I have a problem - BAM uses floating data types that is not supported with exp but is supported with expdp. However, expdp does not allow compression on the fly. I'm stuck. I can't possibly convert to data pump given the lack of space available to perform the expdp.

no, and it is not supported even in 10203, Larry knows that would happen in 11.

I think the question has been asked before but I'm hoping that 10.2.0.3 has changed things - can we do a compress on the fly with expdb now? Ie. using mknod. Has anyone managed to get this to work?
