A hub may receive event data captured by a body-worn device and store the event data in a memory of the hub. The event data is then backed up from the hub to a memory of an additional hub communicatively connected to the hub. A copy of event data for a predetermined period of time as included in the event data is then transferred from the memory of the hub to a data store of a network operations center (NOC). In response to the transfer being complete, the hub may delete the event data for the predetermined period of time, send a first command to the additional hub directing the additional hub to delete a backup of the event data for the predetermined period of time, or send a second command to the body-worn device directing the body-worn device to delete the event data for the predetermined period of time.
