Data recovery method and device of storage equipment, medium and equipment

Abstract

The invention relates to the technical field of data storage, in particular to a data recovery method and device of a storage device, a medium and a device.When a data storage instruction is received, a storage state corresponding to a first storage device is queried, and when a storage state result is normal, initial data and related data are stored in the first storage device, so that the data recovery efficiency is improved. The second storage device is backed up according to the preset backup rule, and the third storage device is backed up according to the preset compression algorithm, so that the storage form and the backup mode of the data are enriched; when the storage state result is abnormal, the initial data and the abnormal time point are stored in the second storage device, so that the integrity of data storage is ensured; and when the storage state result is that the storage state returns to normal, the data stored before the first storage device is abnormal is recovered according to the third storage device, and the new initial data during the abnormal period of the first storage device is recovered according to the second storage device, so that the integrity and the high efficiency of data recovery are improved.
