Cross replicate the staging storage between db1 and storage1
The out of warranty servers used by bd1 and storage1 are enough for staging. It would be a waste to replace them for new servers so we will kept them for a while.
As they are out of warranty, we still need to secure the data on them in case of a hardware issue.
The data is stored on zfs dataset and can be cross replicated between db1 and storage1. The volume to replicate can be handled by the servers :
- db1 -> storage1 in normal usage: <20 Mo/mn, in a peak of activity like VACCUM ~ 1Go/mn
- storage1 -> db1 ~300Mo/mn
