Aspects of the present disclosure relate to recovery of a target database system. The method comprises receiving multiple batches of database transactions to form the target database system. The method further comprises generating a single recovery bookmark before beginning processing of a current batch, wherein the single recover bookmark comprises: an earliest open entry for a previous batch, a latest commit entry for the previous batch, an earliest open entry for the current batch, a latest commit entry for the current batch, a transactional identifier, and list of tables to be processed; performing the sequence of database transactions; replacing the list of tables from the single recovery bookmark with a flag value upon completion; detecting a fault condition during the performance of the sequence of database transactions; recovering the target database system using the single recovery bookmark; and resuming the sequence of database transactions.
