A globally distributed scan list is determined. A determination is made whether the first data replica in the first plurality of data stored on a first device is in sync with a second data replica in the second plurality of data on a second device. In response to determining that the first data replica is not in sync with the second data replica, the first data replica is added to an unsynced queue. The neighbor data of the first plurality of data is added to a suspect queue. The priority to check the neighbor data is increased if the neighbor data is already in the suspect queue. Unsynced neighbor data is added to the unsynced queue. The priority for recovery of the data in the unsynced queue is determined. The priority is based on the vulnerability of the data. A data replica in the unsynced queue is recovered.
