A unique connection ID is associated with each Double-Take Availability connection. The connection ID provides a reference point for each connection. The connection ID is determined by sequential numbers starting at one (1). Each time a connection is established, the ID counter is incremented. It is reset back to one each time the Double-Take service is restarted. For example, if the Double-Take service was started and the same replication set was connected to five target machines, each connection would have a unique connection ID from 1 to 5. The connection can be in various states as described in the following table.
| Connection Status | Description |
|---|---|
| Started |
The network connection exists and is available for data transmission. Replication and mirror data are transmitted to the target as soon as possible. This is the standard state that you will see most often. |
| Stopped | Double-Take Availability has linked the source and target, but the network connection does not exist. Replication and mirror data are not transmitted to the target but are held in queue on the source. |
| Paused |
The network connection exists and is available for data transmission, but the replication and mirror data is being held in a queue and is not being transmitted to the target. |
| Scheduled |
Double-Take Availability has linked the source and target, but the network connection is not established until event driven or scheduling criteria have been met. |
| Error |
A transmission error has occurred. Possible errors include a broken physical line or a failed target service. |
