Also, do not use the streaming compression any more - 'compress::....'. It has been deprecated.
Instead use the 'compress = <compression level>' syntax in your dump database command and investigate compression levels 100 and 101. These levels utilize all cores during the dump to improve performance, whereas the older compression levels 1-9 only used a single core.
In addition, these dumps contain detail about the compression level used internally, so can be used to restore using the 'Archive Database Access' feature for object-level recovery when needed.
