ok, smaller DLEs is fine. we have been doing this. i just thought using span was the only way for amanda to intelligently change tapes when a tape got full. we use a changer script. is that all we need to ensure it will change tapes when a tape gets full? for instance, we just want to make sure amanda will look at the size of the next dump, and move onto a new tape if needed. right? we use a holding disk also, which im sure makes it easier for amanda to know when to change tapes. ultimately we want to setup the right DLEs, and archive a whole proejct, around 6tb at at time. no interaction in this process is key. +---------------------------------------------------------------------- |This was sent by [EMAIL PROTECTED] via Backup Central. |Forward SPAM to [EMAIL PROTECTED] +----------------------------------------------------------------------
