This sync module leverages the versioning feature of the S3 objects in RGW to
|
|
|
|
|
have an archive zone that captures the different versions of the S3 objects
|
|
|
|
|
as they occur over time in the other zones.
|
|
|
|
|
|
|
|
|
|
An archive zone allows to have a history of versions of S3 objects that can
|
|
|
|
|
only be eliminated through the gateways associated with the archive zone.
|
|
|
|
|
|
|
|
|
|
This functionality is useful to have a configuration where several
|
|
|
|
|
non-versioned zones replicate their data and metadata through their zone
|
|
|
|
|
gateways (mirror configuration) providing high availability to the end users,
|
|
|
|
|
while the archive zone captures all the data updates and metadata for
|
|
|
|
|
consolidate them as versions of S3 objects.
|
|
|
|
|
|
|
|
|
|
Including an archive zone in a multizone configuration allows you to have the
|
|
|
|
|
flexibility of an S3 object history in one only zone while saving the space
|
|
|
|
|
that the replicas of the versioned S3 objects would consume in the rest of the
|
|
|
|
|
zones.

How to Configure
|
|
|
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
See `Multisite Configuration`_ for how to multisite config instructions. The
|
|
|
|
|
archive sync module requires a creation of a new zone. The zone tier type needs
|
|
|
|
|
to be defined as ``archive``:
|
|
|
|
|
|
|
|
|
|
::
|
|
|
|
|
|
|
|
|
|
# radosgw-admin zone create --rgw-zonegroup={zone-group-name} \
|
|
|
|
|
--rgw-zone={zone-name} \
|
|
|
|
|
--endpoints={http://fqdn}[,{http://fqdn}]
|
|
|
|
|
--tier-type=archive
