Abstract

Official abstract text for this publication.

An example file server manager updates a selected share of a destination distributed file server based on a snapshot of at least a portion of a selected share of a source distributed file server. The selected share of the destination distributed file server is updated while the source distributed file server serves client requests for storage items of the selected share of the source distributed file server. The file server manager receives a request to failover from the source distributed file server to the destination distributed file server and configures the destination distributed file server to service read and write requests for storage items of the selected share of the destination distributed file server. The file server manager further redirects client requests for storage items of the selected share of the source distributed file server to the destination distributed file server by updating active directory information.

First claim

Opening claim text (preview).

1 . At least one computer readable medium encoded with instructions which, when executed, cause a system to perform operations comprising: updating a selected share of a destination distributed file server based on a snapshot of at least a portion of a selected share of a source distributed file server, the selected share of the destination distributed file server corresponding to the selected share of the source distributed file server, wherein the selected share of the destination distributed file server is updated while the source distributed file server serves client requests for storage items of the selected share of the source distributed file server; receiving a request to failover from the source distributed file server to the destination distributed file server; configuring the destination distributed file server to service read and write requests for storage items of the selected share of the destination distributed file server, wherein the configuring is responsive to the request to failover from the source distributed file server to the destination distributed file server; and redirecting client requests for storage items of the selected share of the source distributed file server to the destination distributed file server by updating active directory information for the source distributed file server to reference the destination distributed file server.
