Hi,
for question #2:

Yes you have to create different pool, the firts reason is that usually incremental bck lives less than a Full backup, the duration is into the Pool information

So in my case I have
- p-daily  INCREMENTAL with 6 volumes (duration 7 days)
- p-weekly DIFFERENTIAL with 4 volumes (duration 1 month)
- p-monthly FULL with 6 volumes (duration 6 month)

In this way I'm able to cover 6 month


Hope to be usefull

I have recently started using Bacula and have a couple of questions
regarding volume pools.  I am using 7.2 version, and we have 4 Linux
servers with a total of about 100GB of data to backup.

1.  We have two different storage devices that are in different
locations (because of bandwidth limitations).  Should we be creating
different Volume Pools for each storage location?

I've tried testing using one pool, and two pools.  When I use one pool
and a backup job is run it displays an error "Marking Volume
"Vol-0001" in Error in Catalog." and then it continues to run.   When
I setup two different volume pools it doesn't display this error.

2.   I've noticed that some people recommend setting up different
volume pools for Full, Differential and Incremental jobs. Is this
still a recommended strategy for Bacula with backing up to disk, and
if so when would someone use this strategy?

The documentation here
http://blog.bacula.org/whitepapers/CommunityDiskBackup.pdf doesn't
mention this.  I don't want to set things up, and then our volumes
grow too large and have to re-do everything.


Thank you,
