Description
Technical Field
The invention relates to the technical field of data backup, in particular to a data parameter backup and recovery method.
Background
When data in a storage medium is damaged or lost, there is often a data recovery method used to recover or reconstruct the damaged data, whereas a general data recovery method not only recovers or reconstructs the damaged portion, but also recovers the entire volume from the backup disc. When a backup disc is placed at a remote location or an amount of data exceeding the damaged portion of data needs to be restored from the backup disc, for example, when a user only needs to restore 5 bytes of data and the system is restored to 500 megabytes of data, the performance of the system may be degraded.
One existing approach to higher recovery efficiency is to add additional redundancy resilience by copying or adding parity pairs to data stored in a local, relatively fast-speed storage medium. In redundancy mechanisms, corrupted data is typically recovered quickly and without delay from the metadata and redundancy coefficients in the system, meaning that the data reconstruction time by redundancy techniques is effectively reduced compared to recovery for the whole volume.
Another approach is to perform data backup, which is typically used in disaster recovery, when the data redundancy mechanism is unable to recover or reconstruct the corrupted data. Because the data backup is periodic, the newly written or updated data is not backed up in the backup disk, i.e., when the redundancy mechanism fails, the newly written data is the most vulnerable, as it cannot be restored by nor from the redundancy mechanism.
Retrieval of chinese patent No. CN106021029a discloses a device and method for recovering backup of NV parameters, said device comprising: the backup module is used for acquiring the NV parameter data from the NV storage area and uploading the NV parameter data to the server for backup; the request module is used for sending an NV parameter recovery request to the server when the NV parameter is abnormal; and the recovery module is used for receiving the backup NV parameter data sent by the server and writing the NV parameter data into the NV storage area. Therefore, the NV parameters are automatically backed up and restored directly on the mobile terminal, a computer and a high-pass software tool are not needed, the operation process is simplified, and the operation efficiency is improved. Meanwhile, the NV parameters are backed up in the server, so that the problem that the NV parameters of the backup are damaged due to the failure of the mobile terminal is avoided, and the reliability of the backup is improved. However, the upgrade is still improper, so that important data in the device is destroyed and cannot be recovered, and the device is seriously disabled.
