.SH DESCRIPTION
|
|
.PP
|
|
Replication is designed to keep the system in a consistent state in the face of
|
|
temporary error conditions like network outages or drive failures. The replication
|
|
processes compare local data with each remote copy to ensure they all contain the
|
|
latest version. Object replication uses a hash list to quickly compare subsections
|
|
of each partition.
|
|
.PP
|
|
Replication updates are push based. For object replication, updating is just a matter
|
|
of rsyncing files to the peer. The replicator also ensures that data is removed
|
|
from the system. When an object item is deleted a tombstone is set as the latest
|
|
version of the item. The replicator will see the tombstone and ensure that the item
|
|
is removed from the entire system.
