The only disadvantages we have come across so far are...

If the journaling service is stopped for any reason, the next time a backup is 
run, it will be a full incremental, meaning it will once again inspect all of 
the files on the client, because it can't determine which ones may have changed 
while the service was stopped.

You can however change a setting in the TSMJBDB.ini file that tells TSM to keep 
the journal database and reuse it if the journaling service is stopped and 
restarted, the option is 'PreserveDBOnExit=1', the disadvantage to this is that 
any file changed while the service is stopped will not get backed up then.

Otherwise, Journaling has been very useful for us.

what platform are you running(OS on client and server)?
code levels(client & server)?
is journaled backup in use?
how is the client connected to the server (what network)?

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.
