What is the difference between rmt2.1 and rmt2.4 ?
When I can use the first one or the another one?

My question is because my hypertape provider told me that there is a question about the rewind of the tape by the OS.

The tape library make all the process load and unload the tape, make the backup but doesnt make the rewind.

That´s why I ask about the different devices found in the devices directory.

I hope you get the idea about this.



Thanks everyone for your comments and tips.

the second digit has a special meaning, see

2.1: rewind on close: no
2.4: rewind on close: yes

Thanks funksen
