Our bottleneck is the network. For that I made a test with this compression tool while the servers where on their daily job. It seems the multi-threading bzip2 is compressing round about 50 percent more data at the same time than bacula shows for the average transferrate of the uncompressed data. But I think for a significant benchmark I have to measure the average transferrate of the whole nightly backup process including the compression step. -- Ralf Brinkmann ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
