Ernie, your application creates logs from finance, these take up tons of
space. you should either create a separate tape of them and purge or create
a separate volume and not back them up every backup. can you send me a
report @."prodacct", also, if you are using a separate test environment on
the same system you should review the frequency of use. I am sure you purge
system logs as well. log####.pub.sys
