Hello,
Bacula does its best not to prune the only good Full, but I am
not 100% sure it always works, so in general the bad situation
that you foresee should not happen. However, Bacula has a number
of techniques for resolving the problem. See below:
1. Use the Reschedule On Error directive.
2. Use the Max Full Interval to make sure your next
Incremental/Differential is upgraded to a Full.
There are probably other techniques that will work too ...
Best regards,
Kern

Assuming the specified schedule, volume retention, and job
retention... is there a possibility that you can have a failed
full backup on the 1st Sunday that leaves you without any backup
for 24 hours? (Previous full one has expired in terms of
retention, which kills all incremental and differentials for the
previous month. So, doesn't it mean that there is no backup
until the next one completes?)
Should retention periods be setup so that they are 1 month + 1
day?
Also, it seems that job and volume retention should be the same
in most cases. It appears to not be useful to have one without
the other. job without volume can tell you where the file used
to be, and volume without job makes it near impossible to find a
given file... correct?
