I am having issues backing up a large Linux server (client=5.2.3.0).

The TSM server is also on a RH Linux box (5.2.2.5).

This system has over 4.6M objects.

A standard incremental WILL NOT complete successfully. It usually
hangs/times-out/etc.

The troubles seem to be related to one particular directory with
40-subdirs, comprising 1.4M objects (from the box owner).

If I point to this directory as a whole (via the web ba-client), and try
to back it up in one shot, it displays the "inspecting objects" message
and then never comes back.

If I drill down further and select the subdirs in groups of 10, it seems
to back them up, with no problem.

So, one question I have is, anyone out there backing up large Linux
systems, similar to this ?

Any suggestions on what the problem could be.

Currently, I do not have access to the error-log files since this is a
protected/firewalled system and I don't have the id/pw.

We have noticed that TSM becomes very inefficient for filesystems with
over 1M files in them. We found that this seems to be a TSM server
database issue. The same server instance performs very well for smaller
filesystems.

Another issue could be the filesystem itself. Some filesystems (ext2)
are very bad at handeling very large directories.
