Thank you for your quick answer. If it is an option for you, i will help to test an new available agent. Pls let me know.

What do you think about NDMP protocoll? Does this protocoll enable a communication between arcserve and DSSV6? Is this something like a "standard" agent for backup, because there is also an optinal arcserve agent for this(!)

Or does this mean, arcserve can only backup DSS V6 content to a local attached tape?
