We have recently been made aware of an issue that has existed in N-central since N-central 12.2, where the Asynchronous Restore method will not properly restore historical data. We are actively working on a fix for this, and anticipate this fix being included in a future release of N-central. Until this issue is fixed, we strongly recommend not using the Asynchronous Restore method in production environments or Disaster Recovery situations.
