Not having an EDL or anything like it on my site, this discussion has me
curious. Correct me if I am wrong, but doesn't the CDI feature simply

NetWorker to do on demand tape drive cleanings? Right? Perhaps this is a
silly question, but why would a disk-based backup device care about tape
cleanings in the first place, or am I missing something?
