Very easily!  The problem is not that you are only backing up 12,222 files, but 
unless you are using the Journaling service, TSM has to look at each one of 
those 4,000,000+ files to see if it needs to back it up or not.  The 10 hours 
is being spent doing this.  We have many clients in this situation, when we 
implement the Journaling service, we take this 10 - 12 hour back ups and make 
them 5 - 10 minutes!  I would be concerned with losing connection though, it 
could just be that the client is taking so long to process at its end that it 
will not talk to the TSM server often enough.  I would try out Journaling and 
see how that helps.

Does anyone think a computer that has this many files on it, that only
backed up 12,222 files, should take over 10 hours to complete? I'm having a
problem with this node dropping out a couple of times a night for being idle
for more than 60 minutes too.

We've double checked the NIC and switch port for the proper settings. When I
looked at it last night the CPU wasn't doing anything.
