Matthias,
Thanks for the help. Yes my boss DOES have large active .pst files, several
(2~3). Each are at or above 1.5 GB in size. Total capacity of the backup is
around 25GB. I've excluded many files and folders although I would like to
include the .pst files as she needs the history these represent. Any ideas on
how to increase the throughput? 100 MB connection on the LAN, when I get the
server from test mode to production the connection will be 1 GB after moving to
the server room. Will increased ethernet bandwidth decrease backup speed
significantly?
Thank you,
Brian

Maybee your boss had a lot of new (big) files?
Try to activate logging (add -vvv to the RsyncArgs) and check if always the
same file is the last before abort.
I have had a similiar problem with a very big outlook.pst in combination
with a network interruption.
