.SH SYNOPSIS
.LP
.B swift-account-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. Account replication uses a combination of hashes and shared high
water marks to quickly compare subsections of each partition.
.PP
Replication updates are push based. Account replication push missing records over
HTTP or rsync whole database files. The replicator also ensures that data is removed
from the system. When an account 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.
