The invention discloses a real-time online backup method and device for a distributed time sequence database, and the method comprises the steps: generating a target write-in identifier corresponding to a target write-in operation when the target write-in operation used for writing target business data into the distributed time sequence database is detected; determining one or more target data partitions corresponding to the target business data; generating a target data write-in record matched with the certain business data based on the target write-in operation and the target write-in identifier; and the target data writing record is stored in a data log of the distributed time sequence database. Visibly, when the business data is written into the plurality of data partitions, the same write-in operation can be associated by adopting the same write-in identifier, so that the association degree between the backup data of the same write-in operation is improved; therefore, when data recovery is carried out ac
