Dear Morty

I use Bacula to backup laptops about 35 in total and assume they may 
connect to the network between 9:00 and 10:30 so I use

   Reschedule On Error = yes
   Reschedule Interval = 45 minutes
   Reschedule Times = 2

in jobdefs.conf

I also split the the laptops into 5 groups so that on one day of the 
week they are scheduled for a full backup. Due to disconnections the 
backups are to disc with only the Full backups migrated to tape. It 
seems the problem of a disconnection during a backup is not completely 
fixed.

The new version of Bacula 3.0 has a greatly improved migration with 
seeks in the disc volume for a clients data - my estimate it has halved 
the time taken for migrations.

Regards
Stephen Carr
