Problems solved by technology

[0002] In the actual storage design test, it was found that the incremental remote replication relationship of the existing storage system is clumsy, and the security is insufficient. The incremental volume and the source volume are in the same Raids group or the same pool or the same external storage system.
With this design method, once the system or RAID group or Pool where the source volume is located is down, the incremental volume will be down at the same time, resulting in the remote incremental volume not receiving data in time and resulting in incomplete data, making the incremental volume Volume remote replication has obvious flaws in data protection

Embodiment Construction

[0016] The invention provides a new incremental asynchronous remote replication design method, which separates the incremental volume and the source volume on different local storage devices, so that the incremental volume and the source volume are physically isolated, and the incremental volume is transmitted through FC, IP or wireless. The network transmission mode automatically transmits data to the remote storage according to the asynchronous transmission time interval according to the saturation degree of the existing performance of the storage system.

[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments.

[0018] Using the method of the present invention, the incremental volume and the source volume are separated on different local storage devices, so that the incremental volume and the source volume are physicall...

Abstract

The invention discloses a novel increment asynchronous remote duplicating design method, and relates to the technical field of remote storage. An increment volume and a source volume are arranged on different local storage equipment separately, so that the increment volume and the source volume are physically separated, and the increment volume automatically transmits data into a far end storage through an FC or an IP or in a transmitting mode of wireless network according to an asynchronous transmitting time interval and the saturation of existing performance of a storage system. By means ofthe method, the increment volume and the source volume are separated in geographic position, and a protection mechanism of the increment volume and the source volume is improved, so that after a poolof the source volume breaks down, a pool of the increment volume can still normally transmit data of the increment to the opposite end; after the pool of the increment volume breaks down, the source volume can automatically generate a new increment volume without causing asynchronous relation losing or asynchronous data losing.

Description

technical field [0001] The invention discloses a novel incremental asynchronous remote replication design method, which relates to the technical field of remote storage. Background technique [0002] In the actual storage design test, it is found that the existing storage system incremental remote replication relationship is clumsy, and the security is insufficient. The incremental volume and the source volume are in the same Raids group or the same pool or the same external storage system. With this design method, once the system or RAID group or pool where the source volume is located goes down, the incremental volume will be down at the same time, resulting in the remote incremental volume not receiving the data in time, resulting in incomplete data, making the incremental volume unavailable. Large-scale remote replication has obvious shortcomings in data protection. The present invention provides a new incremental asynchronous remote replication design method, which iso...
