Storage volume data recovery method and system, storage medium and equipment

The invention provides a storage volume data recovery method and system, a storage medium and equipment, and the method comprises the steps: creating a storage volume in a first storage pool, distributing a storage unit for the storage volume, and recording the distribution condition; in response to the storage volume being mistakenly deleted, determining whether the mistakenly deleted storage volume experiences overredistribution through the recorded content; in response to the fact that the storage volume deleted by mistake is not subjected to reallocation, creating a new storage volume from the second storage pool, and reading a metadata area corresponding to the storage volume from the storage unit; and reading corresponding data based on the metadata in the metadata area, and writing the corresponding data into the new storage volume. The data in the storage volume deleted by mistake can be recovered to the new storage volume, and data loss is effectively prevented. 本发明提供了一种存储卷数据恢复方法、系统、存储介质及设备，方法包括：在第一存
