-rpo Recovery point objective (RPO), which is the acceptable amount of data, measured in units of time, that may be lost in case of a failure. -remote_system_id Unique identifier of the remote system to which this rule will replicate the associated resources. -alert_threshold Acceptable delay in minutes between the expected and actual replication sync intervals. The system generates an alert if the delay between the expected and actual sync exceeds this threshold. -async Perform asynchronous operation. replication_session Use this resource type to manage replication sessions for storage resources in the system. Replication sessions operate on volume and volume_group resource types. Replication sessions are created and deleted through protection policies on the storage resources. In addition to copying data, the replication session synchronizes configuration changes on source resource and replicates user and scheduled snapshots to destination system. Replication sessions provide disaster recovery failover, reprotect and failback capabilities. As a result: • The downtime-associated cost of a system failure is minimized. • The recovery process from a disaster is facilitated. Replication sessions also provides pause and resume capabilities, to allow for production or disaster recovery-side maintenance requirements. Destination storage resources are in replication destination mode, which disables any write access to the destination resource. Any operations such as resizing the volume, restoring the snapshot, or changing membership for a volume group on the resource are not allowed. On the source end, volumes can be expanded, and volume group membership changes are allowed during any states of a replication session. A replication session. This resource type has queriable associations from remote_system, migration_session, replication_rule Attributes 176

-rpo
Recovery point objective (RPO), which is the acceptable amount of data, measured in units of
time, that may be lost in case of a failure.
-remote_system_id
Unique identifier of the remote system to which this rule will replicate the associated
resources.
-alert_threshold
Acceptable delay in minutes between the expected and actual replication sync intervals. The
system generates an alert if the delay between the expected and actual sync exceeds this
threshold.
-async
Perform asynchronous operation.
replication_session
Use this resource type to manage replication sessions for storage resources in the system.
Replication sessions operate on volume and volume_group resource types. Replication sessions are
created and deleted through protection policies on the storage resources.
In addition to copying data, the replication session synchronizes configuration changes on source
resource and replicates user and scheduled snapshots to destination system.
Replication sessions provide disaster recovery failover, reprotect and failback capabilities. As a
result:
The downtime-associated cost of a system failure is minimized.
The recovery process from a disaster is facilitated.
Replication sessions also provides pause and resume capabilities, to allow for production or
disaster recovery-side maintenance requirements.
Destination storage resources are in replication destination mode, which disables any write access
to the destination resource. Any operations such as resizing the volume, restoring the snapshot, or
changing membership for a volume group on the resource are not allowed.
On the source end, volumes can be expanded, and volume group membership changes are allowed
during any states of a replication session.
