Hello all,
I am looking for a new strategy for our backups.

We use Bareos since 2 years and at first we were doing full backup every month. 
The company growing fast, we had to change the schedule to full backup every 
three months with differential every week. 

Now we are in another bottleneck. Actually two but they are related. The first 
one is that we have 3-4 jobs that needs to run for days for a full backup. 
Bareos is configured to cancel lower level jobs but now each three months, it 
takes about 15 days to backup everything. During that 15 days, we are missing 
quite a lot of daily backups and the situation is not going to get better with 
more and more data to backup.

The related issue is that the first differential backups done every week are 
going fine but the more we approach the new full backup, the more bigger and 
longer the differential backups. And as I said earlier, it's mostly because of 
3-4 jobs.

I have tried to add concurrent jobs but since Incr/Diff/Full backups are done 
on three different Pools, the lower level jobs get stucked anyway because the 
SD is mounted with a higher level Pool volume. 

My think-in-progress strategy would be to do those big jobs on another SD 
running in parallel but I would like to know if you guys have other ideas.

Thanks for helping,

O.
