Abstract

A computer implemented method for replication includes registering a first database system with a second database system and performing a failback operation on the first database system. The failback operation includes opening a snapshot that includes data known to have existed on the first database system and the second database system at a first time. Transaction log information is requested from the second database system. The transaction log information corresponds to transactions performed on the second database system beginning with the first time. The transaction log information is applied to the snapshot data on the first database system. Related apparatus, systems, techniques and articles are also described.
