Hello, It has nothing to do with Bacula having a problem, but is just math.
Having a PhD in math would help, but it really doesn't require that much schooling. It is simple math of averages. If you are driving 1000 miles and after 1 minute you stop for 10 minutes, your average speed drops to almost nothing, then gently climbs up to almost the average speed that you would have if you did not stop. > Date: Wed, 13 Jun 2007 09:23:18 +0200 > From: "Stephan Heine - [Genetic Interactive]" <[EMAIL PROTECTED]> > Subject: [Bacula-users] ClientRunBeforeJob Performance Query > To: <Bacula-users@lists.sourceforge.net> > Message-ID: <[EMAIL PROTECTED]> > Content-Type: text/plain; charset="us-ascii" > Hi all, > I am performing 2 Jobs that use the ClientRunBefore feature at a > specific client. > The first Job is a State Backup (Win32) of about 8GB. > The Second is a Exchange Backup of about 32GB. > The State and Exchange Backups are performed using > NTBackup on local an Bacula then grabs the completed BKF file. > Both of these Jobs execute without a problem, but > takes an incredibly log time to complete.
