The invention relates to the field of databases, in particular to a database disaster tolerance synchronization method based on packet replication and a database system. The invention provides a refined synchronization control mechanism based on a grouping strategy aiming at the problem that a unified global synchronization strategy cannot meet refined and differentiated requirements of distributed applications on data consistency, availability and performance in the existing database replication technology. Multiple groups of standby libraries adopt different synchronization levels to perform grouping copying in the same database; a logic abstraction layer of a synchronization group is introduced, a synchronization strategy and a physical standby library are decoupled, and multiple different synchronization mechanisms of a master-slave replication process are allowed in a database; a synchronous waiting mode of a traditional single path is broken through by utilizing a multi-waiting queue and a grouping ACK processing mechanism, so that state advancement of different groups does not interfere with each other; and checking is completed based on the consistency of the state mask, so that the transaction can be successfully returned only after all specified synchronization conditions are met, and the strong consistency of data is ensured.

Method, computer program product, and computer system are provided. A controller component verifies the state of all file sets. The controller component initiates a sub-controller component, based on successfully verifying the state of the file sets. The sub-controller component suspends write operations to all databases at the primary site computer. Based on the suspending completing without error, the sub-controller executes point-in-time copy processes for each of the databases and for application non-database files at the primary site computer. Applications using the databases and non-database files are not suspended. Based on all of the point-in-time copy processes completing without error, the sub-controller component resumes write operations to all databases at the primary site computer. The point-in-time copies are automatically sent to the secondary site computer so that the applications can operate at the secondary site computer if the primary site computer becomes unavailable.

A system and method for performing replication using mediums. A snapshot ‘S’ is selected for replication, and the anchor medium ‘M’ of S is identified. The replica storage array ‘R’ to which M is being replicated determines a list of medium extents which are available. R sends this list to an original storage array ‘O’ and O generates a list of medium extents which need to be sent to R. Only those medium extents corresponding to M which R does not already have will be sent from O to R. Also, R can obtain medium extents from other source storage arrays during the replication process.
