Re: [Bacula-users] cancelled duplicate job shows up as failed

OK, to indicate where the problem is..

I have these assumptions about backup-jobs (tell me if some of them are 
insensible):

1) Full and differential backups must always run on friday - otherwise jobs 
lasting more than 12 hours may disturb working.

2) If full or differential backup fails, it must be ran again - otherwise full 
backups may start aging and thus needed backup SLAs may not be met.

3) Duplicate jobs must not run - if a full job lasts more than 24 hours and 
there is another job starting in 24 hours, full backups will cycle forever.

Anyone else having these assumptions?

To my understanding it is currently not possible to configure this kind of job 
with options ("Rerun Failed Levels = yes" and "Allow Higher Duplicates = no") 
meant straight for that, because they do not work well together.

The best compromise seems to be throwing out assumption 2 and setting "Max 
Full Interval" to force full backups being up-to-date, but this setting may 
cause a full backup to start on a wrong week-day (that could be a serious 
problem in some cases).
