I have a Windows cluster that backs up some large flat file database backups. There are several files that are anywhere from 500GB to 1TB in size with the typical total size of the backup being 2 to 3TB. Is there any way that I could reduce the backup time for this cluster? The resourceutilization is set to 10 and the maxnummp is set to 8 but these don't come into play when there is a single 1TB file being backed up. Could I get better performance by playing with tcpwindowsize, txnbytelimit and/or tcpbuffsize parms on the client?
