Tim,
Assuming the dsmsched.log extracts are not heavily edited, it looks like
you only back up C:? If so, then this kind of elapsed time is typically due
to the time it takes for the TSM server to send the current active backup
inventory back to the TSM client before the client starts traversing the
file system. The most likely cause is a large number of objects (tens of
millions) coupled with a busy TSM server or network. Another possibility is
a TSM client TCPWINDOWSIZE that is larger than the default value (which
happens to be 63), which can severely impact the time it takes for the
client to read data sent by the server if the client machine and network
are not enabled for large TCP window size support (e.g., RFC 1323).
