Hello Henrik, what are you using? MySQL?

Not really. We have several 10+ million file jobs - all run without problem (backup and restore). I am aware of the fact that a lot of Bacula users run PG ( Bacula Systems also does recommend PG for larger setups ) but nevertheless MySQL has served us very well so far. > >Just curious as a fellow Solaris deployer... > >Thanks, >Shon > >On Fri, Oct 8, 2010 at 3:30 PM, Henrik Johansen ><hen...@scannet.dk<mailto:hen...@scannet.dk ><mailto:hen...@scannet.dk%3cmailto:hen...@scannet.dk>>> wrote: >'Mingus Dew' wrote: >All, >I am running Bacula 5.0.1 on Solaris 10 x86.
