I know those three reasons: - simultaneously spooling and despooling increases the requirements of your spool space storage system even more - it's never been implemented - it's probably harder to implement than it looks at first. > Let's say if the spool is reaching a waterlevel mark, the storage daemon > will start to write the spool data to tape _and_ at the same time the > backup client still sends data to the spool directory. Isn't that possible? It's not possible now, but IIRC this has been discussed quite often, but, while many users thought it might be a nice feature, nobody started actually working on it. There's actually a feature request regarding that, though it isn't on the web site yet. It is, though still unnumbered, in the projects file of the git tree.
