OK, it sounds like CPU is not the problem here. > > Did you try using spooling? > > > > Yes, it puts an enormous load on the backup server; I'm not sure why. > I do utilize spooling for incrementals, but I expect them to be > slower (which they are). Spooling splits the backup into phases of collecting from the client, writing to the tape (repeated) and then writing to the database. It could be worthwhile investigating the spooling slowness to see if it occurs in one particular phase (look at the console output for spooling messages). Without spooling it might be difficult to detect which phase is slow because they are interleaved for each file sent by the client. __Martin ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
