Problems solved by technology
In traditional storage technology methods, data copying can often be completed between two servers. However, when an abnormality occurs on one end of the server or the network, the DRBD synchronization data will be disconnected directly, and the written data will be lost. Low security performance and poor disaster tolerance
Even, in some storage processes, if a server at one end has a single point of failure, it is likely to cause the system to be paralyzed, and it cannot provide external services all the time.

The invention discloses a storage method and device. The first main storage server continuously receives the to-be-stored data and sends the received to-be-stored data to a first distributed copying device to be stored as first storage data, and the first distributed copying device sends the first storage data to at least one first standby storage server or a second standby storage server to be stored; if the first main storage server breaks down, a second main storage server is started, the second main storage server receives the to-be-stored data, and the to-be-stored data is sent to the first distributed copying device to be stored as second storage data; and the first distributed copying device sends the first storage data and the second storage data to the first standby storage serveror the second standby storage server for storage. The storage device applies the method. Therefore, according to the storage method and device, data loss is well prevented, the safety performance ofthe data storage process is improved, and the data disaster recovery backup capacity is enhanced.
Description
technical field [0001] The present invention relates to the technical field of information storage, in particular to a storage method and device thereof. Background technique [0002] Distributed replicated block device, or DRBD, refers to a software-implemented, shared-nothing, storage replication method for mirroring block device content between servers. In traditional storage technology methods, data copying can often be completed between two servers. However, when an abnormality occurs on one end of the server or the network, the DRBD synchronization data will be disconnected directly, and the written data will be lost. The security performance is low, and the disaster recovery capability is poor. Even, in some storage processes, if a single point of failure occurs on one end of the server, it is likely to cause the system to be paralyzed, and it cannot provide external services all the time. Contents of the invention [0003] In view of this, the object of the prese...
