Hi,
my
use case for Ceph is serving a central backup storage.
This
means I will backup multiple databases in Ceph storage cluster.
This
is my question:
What
is the best practice for creating pools & images?
Should
I create multiple pools, means one pool per database?
Or
should I create a single pool "backup" and multiple rbd images,
means one rbd image per database?
Or
should I create a single pool "backup" and single rbd image "db"?
This
is the security demand that should be considered:
DB-owner
A can only modify the files that belong to A; other files (owned
by B, C or D) are accessible for A.
