Embodiment Construction
[0042] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.
[0043] Such as figure 1 As shown, a data storage system in this embodiment includes a storage client, a storage agent, and a storage server. In the framework of storage client, storage agent and storage server, data communication between storage client and storage agent, storage agent and storage server is constrained by negotiation parameters, and data transmission and storage can only be performed after parameter negotiation is completed.
[0044]In this embodiment, the storage proxy is used to receive the service parameters reported by the storage server, and notify the storage client of the service parameters. The transfer of service parameters is realized through negotiation. The service parameter negotiation is divided into t...

The invention discloses a data storage system and a storage deletion-correction method thereof. The data storage system comprises a storage client, a storage service end and a storage agent, wherein the storage agent receives service parameters reported by the storage service end, notifies the service parameters to the storage client, receives the data transmitted from the storage client after performing deletion-correction calculation on raw data according to the service parameters, performs packet loss inspection and recovery treatment, and transmits the treated data to the storage service end to be preserved. According to the data storage system and the storage deletion-correction method thereof disclosed by the invention, through the storage agent, the purpose that under the condition of poor network quality, the storage agent can restore data through an anti-deletion-correction algorithm, and the storage client transmits the data in a discrete manner, so that the success rate of the data recovery through the anti-deletion-correction algorithm can be increased, and the data transmission efficiency is improved.
Description
technical field [0001] The invention belongs to the field of data disaster recovery storage, and in particular relates to a data storage system and a storage erasure correction method thereof. Background technique [0002] In many industries that require high data security and reliability, such as the financial industry, insurance industry, and telecommunications industry, in order to ensure high data reliability, data redundancy backup is usually used for disaster recovery. The traditional data disaster recovery method is to fully replicate and back up the original data, and store the backup data on a remote storage server. This method of disaster recovery brings very high costs. Erasure coding implements redundant backup and distributed storage of data by dividing data into fragments and generating redundant data through erasure correction algorithms. This storage erasure correction method not only realizes data disaster recovery, but also reduces costs. [0003] The exis...
