Patent number: 8468128Abstract: Subsequent to a storage operation performed on the source instance by a source component, a synchronization message is sent to a replicated component for the replicated instance. The synchronization message is stored locally in a persistent storage location associated with the source component along with an indicator representative of a time the storage operation was performed. Pursuant to receipt of the synchronization message by the replicated component, the replicated component is updated to a dirty state to indicate a lack of full synchronization between the source and replicated instances. Receipt of the synchronization message is acknowledged by the replicated component by sending a dirty state acknowledgement. If, during a subsequent recovery process, the dirty state is not yet cleared, the replicated component is deemed ineligible for participation in a full restoration operation.Type: GrantFiled: May 4, 2012Date of Patent: June 18, 2013Assignee: International Business Machines CorporationInventors: Shay H. Akirav, Evgeny Budilovsky, Elena Drobchenko, Aharon Lazar, Ofer Leneman, Itay Maoz, Gil E. Paz

Patent number: 8423735Abstract: A calculated factoring ratio is determined as a weighted ratio of current nominal data to physical data based on at least one storage capacity threshold and a used storage space currently physically consumed by one of backup and replication data. A maximal nominal estimated space in the computing storage environment is calculated. A remaining space, defined as the maximal nominal estimated space minus a current nominal space in the computing storage environment, is calculated. If the remaining space is one of equal and less than a user-configured reservation space for backup operations, data replication operations are accepted and stored in the computing storage environment.Type: GrantFiled: May 21, 2010Date of Patent: April 16, 2013Assignee: International Business Machines CorporationInventors: Shay H.

Patent number: 8296536Abstract: A replication synchronization table (RST) is configured for the source instance. The RST is adapted for recording compacted information for at least one of a truncate and an erase operation applied on the source instance. The RST of the source instance is updated at a source component with the compacted information. The updated RST is transmitted from the source instance to the replicated instance. Based on the RST of the source instance and the RST of the replicated instance, data representative of a most recent position on the source component from which data should be transmitted to a replicated component to achieve a full synchronization is determined.Type: GrantFiled: August 11, 2009Date of Patent: October 23, 2012Assignee: International Business Machines CorporationInventors: Shay H.
