Abstract
The invention relates to a backup method for key data in a hybrid SSD, which mainly comprises the following steps: judging whether the data need to be backed up, and for the read operation of the backup data, defaulting that the data of a fast medium is read and a slow medium is used for recovery; and for the write operation of the backup data, selecting a backup mode according to the request size; for a relatively small write request, using accumulative backup, firstly writing two parts of data to a fast medium, and migrating to a slow medium after a certain amount of data is accumulated; for a large write request, writing data into a fast medium and a slow medium at the same time in a traditional backup mode. The invention has the following advantages that by means of the method that the fast medium is written firstly to be accumulated and then migrated to the slow medium, the problems that delay and write amplification are greatly increased due to the fact that the fast medium and the slow medium are written at the same time are solved, and data backup performance and write amplification expenditure can be reduced.
