Replication Storage Pools - Oracle ZFS Storage Appliance Administration Manual

Continuous replication is still asynchronous. The Oracle ZFS Storage Appliance does not
currently support synchronous replication, which does not consider data committed to stable
storage until it is fully committed on both the primary and secondary storage systems.
Intermediate Replication Snapshots
When the "Include Snapshots" property is true, replication updates include the non-replication
snapshots created after the previous replication update (or since the share's creation, in the case
of the first full update). This includes automatic snapshots and administrator-created snapshots.
This property can be disabled to skip these snapshots and send only the changes between
replication snapshots with each update.
Replication Action and Package Relationship
A replication action and package are bound to each other. If the package is somehow corrupted
or destroyed, the action will not be able to send replication updates, even if the target still
has the data and snapshots associated with the action. Similarly, if the action is destroyed,
the package will be unable to receive new replication updates (even if the source still has the
same data and snapshots). A warning will occur, in both the BUI and CLI, if you attempt to
perform an operation that would destroy the action-package connection. If an error or explicit
administrative operation breaks the action-package connection such that an incremental update
is no longer possible, you must sever or destroy the package and action, then create a new
action on the source.
The appliance avoids destroying data on the target unless explicitly requested to do so by
Note -
the administrator. As a result, if the initial replication update for an action fails after replicating
some of the data and leaving incomplete data inside the package, subsequent replication updates
using the same action will fail because the appliance cannot overwrite the previously received
data. To resolve this, administrators should destroy the existing action and package, create a
new action, then restart replication.

Replication Storage Pools

When a replication action is initially configured, the administrator is given a choice of which
storage pool on the target should contain the replicated data. The storage pool containing an
action cannot be changed once the action has been created. Creating the action creates the
empty package on the target in the specified storage pool. After this operation the source has no
