Master server: Solaris 8, NBU 4.5 fp8
Clients: Solaris 8, NBU 4.5 (various)

Does the master do the calculations to determine whether a file needs to be
part of the incremental backup (Differential Incremental) or does the client
do it?

What Logs on the Master or the client could I watch (and turn up the debug
level) to catch what is being "considered" for a backup?

I have some important files that are not getting backed up during
incrementals and now I have to "explain" why they are getting skipped.  I
know the files are not open and not in use by any process.

I can initiate a manual backup from the GUI pick the differential schedule
and watch the job in the activity monitor.  It will exit with a status of 0
(zero) and list no files as being backed up.  Bplist nor bpflist show any
files being backed up during the job.

I can also set the schedule to run very frequently (just to ensure that it
is not an issue with initiating a manual incremental) with the same results.

Thanks.
