Hi Andreas, thanks for your helpful answer!
Ok we know, that we know nothing quite right how its works. ;-) I will test especially this new Feature if a released Version is available in suse rpm format. I would also find statistically overviews of volume usage very helpful for proactive changing havyly used Tapes. ps: i should read more often the project page. ;-) On Wednesday 11 July 2007 writes Andreas Helmcke: > Falk Sauer wrote: > > I mean on any post in the last weeks i've read (only with one eye) over a > > option thats allows a volume after pruning, automatically moving to the > > scratch pool. > > > > That can be a very nice feature, in the moment i make this manually. > > > > From which version of bacula is this option usable and how is the syntax? > > > > > >From the chapter: "The Pool Resource" from the actual bacula manual: > > The Pool Resource > > RecyclePool = <pool-resource-name> > On versions 2.1.4 or greater, Bacula can recycle media in the pool of > your choice.
