Distributed snapshot process
First Claim
1. Systems for providing a partitioned storage service, comprisingat least two servers,a storage volume partitioned across the at least two servers, andat least two snapshot processes operating on respective ones of the at least two servers and capable of coordinating with other snapshot processes for generating state information representative of the state of the partitioned storage volume.

Abstract
Systems and methods for providing an efficient partitioned resource server. In one embodiment, the partitioned resource server comprises a plurality of individual servers, and the individual servers support a storage service. The systems and methods provide archiving processes for a partitioned storage service. To this end, the systems and process may include a snapshot process operating on a server and capable of coordinating with other snapshot processes for generating state information representative of the state of the partitioned storage volume.

10. A process for providing a partitioned storage service, comprising the steps of providing at least two servers and a storage volume partitioned across the at least two servers, and
operating at least two snapshot processes on respective ones of the at least two servers and capable of coordinating with other snapshot processes for generating state information representative of the state of the partitioned storage volume.

17. A process for generating a snapshot of a storage volume distributed across at least two servers, comprising
executing snapshot processes on respective ones of the at least two servers, providing an administration command to a first one of the snapshot processes directing the snapshot processes to generate state information representative of the state of the partitioned storage volume, having the first snapshot process hold pending requests and direct at least a second snapshot process to hold pending client requests, having the second snapshot process to indicate that requests have been held, and having the first snapshot process generate state information representative of the state of a storage partition maintained on its respective server and generate a snapshot command for the second server to generate information representative of the state of a storage partition maintained on its respective server.

21. A storage area network, comprising
a data network having at least two servers, a storage volume partitioned across the at least two servers, and at least two snapshot processes operating on respective ones of the at least two servers and capable of coordinating with other snapshot processes for generating state information representative of the state of the partitioned storage volume.
