Patent number: 10171580Abstract: Methods, systems, and computer program product embodiments for cataloging data in a backup storage environment, by a processor device, are provided. In a storage system using tape library data replication between an originating site and one or more backup sites, data catalog data is replicated between the originating site and the backup site such that replicated data moved from the originating site to the backup site is placed into a catalog duplicative of the originating site.Type: GrantFiled: April 27, 2015Date of Patent: January 1, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Oren Bar, Joseph W. Dain, Elena Drobchenko

Patent number: 9454591Abstract: 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.Type: GrantFiled: February 27, 2013Date of Patent: September 27, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shay H.

Patent number: 9442665Abstract: A calculated factoring ratio is determined as a weighted ratio of current nominal data to physical 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. Data replication operations are accepted and stored in the computing storage environment if the remaining space is below a predetermined threshold of space for backup operations.Type: GrantFiled: November 2, 2015Date of Patent: September 13, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shay H.

Patent number: 8806162Abstract: Visibility of a data storage entity on a first storage system is switched to a replicated data storage entity on a second storage system. Data from the data storage entity is replicated from the first storage system to the second storage system using a common serial number. The data storage entity is hidden from the first storage system by concealing the common serial number. An ejection of the data storage entity from the first storage system is automated, and the replicated data storage entity is introduced to the second storage system.Type: GrantFiled: May 8, 2012Date of Patent: August 12, 2014Assignee: International Business Machines CorporationInventors: Shay H.

Patent number: 8706994Abstract: Various embodiments for synchronization of source and replicated instances of sequential access storage components in a computing environment by a processor device are provided. A replication synchronization table (RST) of a source instance is updated at a source component with the compacted information. 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: January 17, 2013Date of Patent: April 22, 2014Assignee: International Business Machines CorporationInventors: Shay H.

Patent number: 8533412Abstract: 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: April 27, 2012Date of Patent: September 10, 2013Assignee: International Business Machines CorporationInventors: Shay H.
