NTT (1.4.0 & 1.5.0, Windows) - NSRDDRCHK: What does it need to detect a DD?

Hello,

although it is not explicitly mentioned in the book it makes sense to have at least some backup/backup cycles present that this utility will work. On a Linux NW server, it will take about 5 of them so that the DD will be recognized.

However, if you use the same DD from a Windows server, there is no DD recognized even if already 10 backups exist.

Anybody out there who knows the trick?

Thanks and best regards.
