    I think you need to do some tests for yourself (with backup sets you do not care about to see the effects of the different settings. )

    A stand alone tape drive will never appear to work like a library - you get lots of extra choices with a libary because of the fact that there are more tapes online at the same time. That said the overwrite protection and media control do work the same - but have the ability to choose from more than just one tape, hence it looks like the functionility is different (when in reality the stand alone drive just limits all the decisions and rules to the single online tape. )

I will think that a single tape, have the possibility to work like a robotic library, append backups on the tape, like that I have here.

I read your explanation, to finally understand it, if I configure this single tape with allow append and 1 hour overwrite protection, It is possible to have many backups on that ok?
But if is not allow append, the tape are overwrite and data on a tape are destroyed ok?

    Ok, I will try to do some tests here, and combine some options, but I have a problem with the Dell Tape Drive, I Open a Topic about It, and start to see that: https://vox.veritas.com/t5/Backup-Exec/Tape-dissapear-from-the-Library/m-p/853334#M356024
