This application discloses a data rollback method, a memory, an electronic device, and a storage medium. Relating to the field of storage, the method is applied to a memory and includes: in response to a snapshot creation instruction, generating snapshot data corresponding to the target data and a primary snapshot mapping table for orienting the snapshot data; constructing a secondary mapping table for orienting the location of the primary mapping table, where the primary mapping table is used to orient the target data; and in response to a data rollback instruction, switching the mapping update operation from the primary mapping table to the primary snapshot mapping table based on the secondary mapping table, and obtaining the snapshot data for data rollback. This application directly switches the mapping update operation from the primary mapping table, which requires data scanning to obtain the data to be recovered, to the primary snapshot mapping table, which can directly locate the snapshot data, for data rollback based on the secondary mapping table. This avoids lengthy data scanning and improves data rollback speed through a hierarchical mapping table.
