Recovering from lost packets
There are several circumstances in which a replica-creation or update packet is generated but is never applied at one or more of its destinations.
For example:
- The packet is stored on media that is destroyed or is not readable at the destination host.
- A packet file is lost when a hard disk fails.
- The packet is intact, but cannot be applied because another packet has been lost. (See Packets accumulate in incoming storage bay.)
