Replication of data objects from a source server to a target server
First Claim
1. A computer program product for replicating objects from a source storage managed by a source server to a target storage managed by a target server, the computer program product comprising a non-transitory computer readable storage medium having computer readable program code embodied therein that executes to cause the target server to perform operations, the operations comprising:
- receiving a query from the source server for a target list of objects at the target storage satisfying a replication criteria of a replication request, wherein the replication criteria allows for selection and filtering of objects to replicate at an object level;
sending to the source server the target list of the objects at the target storage satisfying the replication criteria;
receiving, from the source server, data for objects to store in the target storage;
receiving, from the source server, metadata for the data received for the objects to replicate not included in the target list;
adding an entry to a target server replication database for each object for which data is received including the metadata received for the object; and
receiving, from the source server, metadata for objects at the source server matching objects at the target server in the target list.

Abstract
Data objects are replicated from a source storage managed by a source server to a target storage managed by a target server. A source list is built of objects at the source server to replicate to the target server. The target server is queried to obtain a target list of objects at the target server. A replication list is built indicating objects on the source list not included on the target list to transfer to the target server. For each object in the replication list, data for the object not already at the target storage is sent to the target server and metadata on the object is sent to the target server to cause the target server to include the metadata in an entry for the object in a target server replication database. An entry for the object is added to a source server replication database.

8. A system for replicating objects from a source storage managed by a source server to a target storage, comprising:
-
a processor; and a computer readable storage medium having code executed by the processor to perform operations, the operations comprising; receiving a query from the source server for a target list of objects at the target storage satisfying a replication criteria of a replication request, wherein the replication criteria allows for selection and filtering of objects to replicate at an object level; sending to the source server the target list of the objects at the target storage satisfying the replication criteria; receiving, from the source server, data for objects to store in the target storage; receiving, from the source server, metadata for the data received for the objects to replicate not included in the target list; adding an entry to a target server replication database for each object for which data is received including the metadata received for the object; and receiving, from the source server, metadata for objects at the source storage matching objects at the target storage in the target list. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for replicating objects from a source storage managed by a source server to a target storage managed by a target server, comprising:
-
receiving a query from the source server for a target list of objects at the target storage satisfying a replication criteria of a replication request, wherein the replication criteria allows for selection and filtering of objects to replicate at an object level; sending to the source server the target list of the objects at the target storage satisfying the replication criteria; receiving, from the source server, data for objects to store in the target storage; receiving, from the source server, metadata for the data received for the objects to replicate not included in the target list; adding an entry to a target server replication database for each object for which data is received including the metadata received for the object; and receiving, from the source server, metadata for objects at the source server matching objects at the target server in the target list. - View Dependent Claims (16, 17, 18, 19, 20, 21)
