Storage : modify MediaType parameter without losing data

[Pierluigi Ruffo]

Hi everyone, I have a Storage Daemon server on which two  storage are defined, which point to two different folders.
Unfortunately it seems that Bareos sometimes cannot distinguish volumes from one storage to another because they are part of the same storage daemon.
The only way would be to define a different MediaType between the two.
This would also be easy if not for the fact that changing the MediaType forces you to lose the data present in the volumes.
Isn't there a way to change the media type without having to initialize the volumes involved and therefore losing the data they contain?

Thanks a lot to everyone
