Completely agree. Move the saveset off. Then, if you're really desperate to 
keep the tape, do a full end-to-end write of it before you use it to write more 
data to it.

Given the cost of tapes, just simply marking a tape as appendable after 
NetWorker has flagged it as full due to a write error is a risky decision in 
terms of long-term preservation of recoverability.
