A method for detecting replication lag is described. In an embodiment, a local timestamp is generated at a first computer. The local timestamp is stored in an electronic folder. If a replication triggering event occurs, the electronic folder is replicated at one or more target computers. If an update triggering event occurs, the local timestamp in the electronic folder is updated. If a detection triggering event occurs, a request for at least a portion of the electronic folder representing the local timestamp is sent to at least one target computer of the one or more target computers. At least the portion of the electronic folder representing the local timestamp is received from the at least one target computer. If the time difference between one or more of the received timestamps and the local timestamp exceeds a threshold amount, a system event is generated. |
