I do apologize, I should have first asked what OS the client was, and what 
version the client is.  Journaling is only available for Windows clients, TSM 
client level 4.2 or higher.  If this is a Windows client 4.2 or higher, run the 
setup wizard and it is one of the options available for setup.  If this client 
does meet this criteria, then Journaling is not available and the best you can 
do is try to fine tune this backup.  We do have Novell clients in similar 
situations, not quite that many files, that we just realize are going to take a 
very long time to backup.

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.
