I am currently looking at BackupExpress as a backup solution for NetWare

I am confused with BEX because it has a GroupWise option - the reason that I
am confused is that all other backup software I have used talks natively
with GroupWise through the TSA - either GWTSA or TSAFS.

My question is will BEX backup GroupWise using the TSA without the GroupWise

What is the advantage of the BEX GroupWise option over using another product
that talks to the TSA's natively?
