Many windows 2003 servers now days can scan one to two million files per hour. 
We don't use journaling until we get over five million files. I've seen the 
deeper the directory structure the longer it takes to scan Basically if all one 
million files are at the root of a drive it will scan much faster then if one 
million files were in hundres of subdirectories.

We currently run TSM 5.3 on an AIX platform and have
a subset group who administer the TSM Clients on the
windows servers. They have been hesitant to turn
Journal Based Backups on because of past issues.

>From what I have seen prior to TSM 5.3 there were a
number of issues with JBB, however, since 5.3 there
have been changes which have fixed prior issues, such
as sessions hanging, disconnects etc...

I just attended a class for TSM in which the
instructor said the only overhead on the client was
about 10MB, the size of the file which houses the
directory entries. 

So my question to this list is, those of you who
utilize JBB is what have you seen as being an
advantages and disadvantages of this feature?

I would like to put together a document which I can
present to the Windows Administrators to move them
towards Journal Based Backups on clients which have
more than 400,000 files.

Thank you,
Shawn Malone
