To add a bit of detail:

All modern Windows versions (except possibly Vista) have a hard-set
limit of total memory that can be dedicated to a single process thread.
(I believe it's 192MB, but don't quote me on that.) It is a hard limit
that cannot be gotten around.

Steve's workaround is an option. The other option is to use two
nodenames for the same machine, with two option files/sets of TSM
services/etc. One node backs up half the machine (by using
include/exclude lines in the option files), and the other node backs up
the other half.

The real fix? Use a real server OS.
