Hello Dave, well, it depends. ;-) On a lot of things, actually. What DB backend are you using? Is the db optimized for bacula usage? How fast are your disks? Are you using attribute / job spooling? What's the hardware spec of the director / sd machine? What's your connection / max throughput to the clients? All the best, Uwe -- ------------------------------------------------------------------------------ _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
