A computer-readable storage medium storing executable instructions which, when executed by at least one computer, cause the at least one computer to perform a method for creating a replica of a source database, the method comprising receiving a backup logical change number for the source database, the backup logical change number corresponding to a transaction committed to the source database; creating, while the source database operates with full data availability for read and write operations, a clone of the source database up to the backup logical change number by capturing transactions committed before the backup logical change number; transferring the clone of the source database to a replica database while the source database continues to operate with full data availability; and initiating an apply process to the replica database by updating the replica database with transactions committed after the backup logical change number |
