description The invention relates to a database backup and recovery method for a financial management system. Compared to the prior art, the method overcomes the defect that the consistency and real-time property of a database cannot be ensured under a condition of system crash. The method comprises the following steps of: database creation: establishing uniform format and specification of database backup; establishment of a log backup file buffer pool: establishing the backup file buffer pool based on a logic time axis B; database backup: carrying out a data backup operation by a database within a time period; and database restoration: restoring backup data by the database. According to the method, data files that are not stored in a cache are re-retrieved when the system crashes and is restarted, and rollback is stored in the database.
