Abstract
The present invention provides a method and an apparatus for performing a full backup for a distributed database system, and a computer-readable storage medium. Said method comprises: acquiring full backup data of each data node in the distributed database system, with a full-backup time point corresponding to the full backup data being a time point; determining a trust divergence time point for the time point, where all transactions in prepared states prior to the trust divergence time point are enabled to be committed or rolled back before the time point; acquiring a first incremental log set of said each data node between the trust divergence time point and the time point; acquiring from the first incremental log set a pending transaction of said each data node; and replaying the pending transaction of said each data node on the full backup data of said each data node.
