.SH NAME
.LP
.B swift-object-replicator
\- OpenStack Swift object replicator

.SH SYNOPSIS
.LP
.B swift-object-replicator
[CONFIG] [-h|--help] [-v|--verbose] [-o|--once]

.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.
