Why is the running time of DBS backup SQL statements different from that displayed in the ApsaraDB for RDS console

Last Updated: Mar 24, 2020

Question

Why is the running time of DBS backup SQL statements different from that displayed in the ApsaraDB for RDS console?

Answer

To guarantee backup data reliability, the UTC+0 time is used when you run a backup SQL statement during a DBS logical backup. However, the UTC+8 time is used in SQL audit logs of ApsaraDB for RDS for the same backup SQL statement. As a result, the running time of the backup SQL statement displayed in the ApsaraDB for RDS console is 8 hours different from the actual running time. The actual running time is subject to that displayed in the DBS console.
