CLIENT OBJECT REPLICATION BETWEEN A FIRST BACKUP SERVER AND A SECOND BACKUP SERVER

摘要

Provided are a computer program product, system, and method for client object replication between a first backup server and a second backup server. Objects are backed-up from a client to a first backup server. The first backup server generates metadata on the objects from the client and transmits the metadata to a second backup server, wherein the objects backed-up at the first backup server are not copied to the second backup server. A determination is made that the first backup server is unavailable after transmitting the metadata. The metadata at the second backup server is used to determine modifications to the objects at the client since the metadata was last generated in response to determining that the first backup server is unavailable. The client backs-up the determined modifications to the objects to the second backup server to backup.

1. A computer program product for backing up objects from a client to a first backup server and a second backup server, wherein the computer program product comprises a computer readable storage medium having computer readable program code embodied therein that executes to perform operations, the operations comprising:
backing-up objects from a client to the first backup server; generating, by the first backup server, metadata on the objects from the client; transmitting, by the first backup server, the metadata to the second backup server, wherein the objects backed-up at the first backup server are not copied to the second backup server; determining that the first backup server is unavailable after transmitting the metadata; using the metadata at the second backup server to determine modifications to the objects at the client since the metadata was last generated in response to determining that the first backup server is unavailable; and backing-up, by the client, the determined modifications to the objects to the second backup server to backup.
