    • A method, a device and a computer for data operation are provided, wherein the method includes that: when a writing data operation to a sector of a storage device is performed, whether the sector belongs to an original storage block of a reduction point of the storage device is judged; if yes, then a new storage block is allotted and the data is written into the new storage block; a table is created, the table includes: an address of the original storage block, an address of the new storage block and a first ID, the first ID has the first ID elements that respectively correspond to the sectors in the original storage block and the new storage block, each first ID element has a first status which represents reading the data from the original storage block when the data of the corresponding sector is resumed, and a second status which represents reading the data from the new storage block when the data of the corresponding sector is resumed; and the address of the original storage block in an address index list of the reduction point is pointed to the table; if no, then a new storage block is allotted and the data is written into the new storage block; and an address of the original storage block in an address index list of the reduction point is modified to an address of the new storage block. The solution of the invention can save the time of operating the sector of the reduction point of the storage device, and can improve the capability of the computer.
    • 提供一种用于数据操作的方法,设备和计算机,其中该方法包括:当执行对存储设备的扇区的写入数据操作时,该扇区是否属于该存储设备的缩小点的原始存储块 判断存储设备; 如果是,则分配新的存储块并将数据写入新的存储块; 创建表,该表包括:原始存储块的地址,新存储块的地址和第一ID,第一ID具有分别对应于原始存储块中的扇区的第一ID元素和 新存储块,每个第一ID元素具有第一状态,其表示当恢复对应扇区的数据时从原始存储块读取数据,以及第二状态,其表示当新存储块的数据 相应部门恢复; 并且减少点的地址索引列表中的原始存储块的地址指向表格; 如果否,则分配新的存储块并将数据写入新的存储块; 并且还原点的地址索引列表中的原始存储块的地址被修改为新的存储块的地址。 本发明的解决方案可以节省存储设备的减少点的操作时间,并且可以提高计算机的能力。
