Good morning,
We are planning to use the Scratch pool for automatically having avaible
tapes in the different pools of my different catalogues.
For this purpose, we planned to create let's say 100 volumes in scratch
and later, that volumes to to be requested by the different pooles AND
of different catalogues, needing new media for continuating backup jobs.
Is this possible or the scratch pool can only share volumes with pools
within the same catalogue?.
If you have multiple Catalogs, you would need to devise a way to
synchronize the state of the Scratch pool across all of them. This is
not functionality that is supported in Bacula. If you have multiple
Bacula directors running from different Catalogs, they need to be
separate, not sort-of-separate-but-with-overlaps. Trying to share
resources between Directors running from different Catalogs will get you
into trouble, because one director will have no way of knowing what
another is using or has used. This could lead to cases where, for
example, one Director performs a critical full backup on a certain set
of tapes, and then the next day another Director that doesn't know it
has done so recycles one of those tapes and uses it for something else,
and the first doesn't know the backup is no longer valid.
What are you trying to accomplish with this multiple-catalogs scheme?
When the answer doesn't make sense, sometimes it means you're asking the
wrong question.
