Why not use mhtvl or quadstor https://quadstor.com/virtual-tape-library.html
http://www.mhvtl.com they are nice solutions and integrate well with Bacula Josh Fisher <jfis...@jaybus.com> escreveu em qui., 27/01/2022 às 18:50 : > > On 1/26/22 12:42, dmitri maziuk wrote: > > On 2022-01-26 11:06 AM, Peter Milesson via Bacula-users wrote: > >> > > ... > >> Your way of explaining the reasoning of why to use smaller file > >> volumes, is very appreciated. > > ... > > > >> The only thing I haven't found out is how to preallocate the number > >> of volumes needed.
