This is something that I have on my personal list to implement, but probably
should be added to the projects file.

Item n: feature to prevent jobs from starting twice
Date: Date submitted
Origin: Martin Schmid [EMAIL PROTECTED]
Status: New
What: I have short term jobs that are run every 90 minutes and a first
full backup that takes significantly longer than the
following incremental jobs is started near midnight. I am
aware of the maximum wait parameters and I'm using them
extensively.
But by chance a following job is well in the allowed maximum
delay while the previous full backup job has
not finished yet . This will start the second job as full
backup even though the preceding job may terminate successfully.
In the end there are two subsequent full backup jobs that
have run. Wouldn't it be possible to forbid any
subsequent job at all? Maybe in the schedule resource..
Why: Space is limited on the drives and and unnecessary full backup
delays other jobs. It would also help recovery after a previous
full backup terminated with error or was canceled or
encountered a long delay
Notes: Example: between two 'Quickbackup' jobs there are 90 minutes.
There is a full backup at 00:30 and the first incremental
at 07:00, the next at 08:30, ...
The full backup job takes some 150 minutes
The full backup may be delayed and end at 07:10. By this
time the first incremental is already started as full backup.
Tuning the maximum start delay parameter or the schedule
just reduce the chance of subsequent full backups without
solving the problem
