A recovery point objective, or “RPO”, is defined by business continuity planning. It is the maximum tolerable period in which data might be lost from an IT service due to a major incident. The RPO gives systems designers a limit to work to. For instance, if the RPO is set to four hours, then in practice, off-site mirrored backups must be continuously maintained – a daily off-site backup on tape will not suffice. Care must be taken to avoid two common mistakes around the use and definition of RPO. Firstly, BC staff use business impact analysis to determine RPO for each service – RPO is not determined by the existent backup regime. Secondly, when any level of preparation of off-site data is required, rather than at the time the backups are offsited, the period during which data is lost very often starts near the time of the beginning of the work to prepare backups which are eventually offsited.
System and method for management of recovery point objectives of business continuity/disaster recovery IT solutions
InactiveUS20060129562A1Digital data information retrievalError detection/correctionIndustrial engineeringRecovery point objective
The present invention provides a system and method for management of Recovery Point Objectives (RPO) of a business continuity or disaster recovery solution. The system comprises a management server logically coupled with at least a first computer, at least a second computer, and a network coupling the first and the second computers. The first and second computers host at least one continuously available application and at least one data protection scheme for replicating the application data; the application data being periodically replicated from the first computer to at least the second computer. The system manages RPO by inputting an RPO value for the solution, calculating a real time RPO value for the solution, and making the real time RPO value equal to the input RPO value.

Apparatus, system, and method for creating a backup schedule in a san environment based on a recovery plan
InactiveUS20080154979A1Minimal disruptionError detection/correctionSpecial data processing applicationsDatabase backupSystem recovery
An apparatus, system, and method for creating a database backup schedule in a SAN environment based on a recovery plan. A user provides a desired recovery point objective (RPO) from a system recovery plan and an identifier of a database for back up. The present invention determines a priority (w) for a recent recovery point and determines a number (N) of volumes for storing backup images and a number (n) of database volumes used by the database. The present invention generates a scheduling formula where RPO is divided by the priority (w) of the most recent recovery point raised to the power of the truncated integer value of the ratio of volumes for storing backup images (N) and the number of volumes in use by the database (n) minus a scheduling interval determinant (i). The scheduling formula is used to determine a backup interval and backup assurance points.

Quality of service for remote copy operations in storage systems
InactiveUS20060095696A1Memory loss protectionError detection/correctionQuality of servicePrimary sites
A system is provided for storage of journal data from a primary site to a secondary site with a predefined quality of service. In one implementation, the primary storage system stores information for updating data stored on the primary disk array in the form of a history of updates made to the data. The primary storage system is configured to transfer this journal information to the secondary storage system. The user can specify the quality of service desired using a variety of measures, for example, a recovery point objective or a recovery time objective. In response, a copy manager within one of the storage systems determines the capacity of the various primary and secondary volumes, and determines the copy rate available, typically dependent upon the bandwidth between the primary and secondary systems. The copy manager then copies journal data to the remote site where it is stored.

ActiveCN102142024AEfficient reductionEasy insertionDigital data information retrievalSpecial data processing applicationsRelational databaseDistributed database
Provided is an architecture that eliminates the need for on-disk full backups of data retaining only changes that have occurred, in a separate table. Thus, the architecture provides for incremental recovery of incremental changes in a relational database (e.g., SQL). The architecture provides improved recovery time and recovery point objectives. By using the incremental capture of changed data (e.g., in an XML format), the capability is provided to capture schema changes, query the incremental change data and efficiently restore user data to an earlier point-in-time state. Changes (e.g., insert, update and delete operations) are tracked (e.g., continuously) by a set of triggers and the incrementally captured changed rows are inserted in a data capture table (a differential change ''delta'' table) in a human-readable format (e.g., XML). Rollback is also provided.

A method and apparatus for scheduling backup tasks on a source system specified by a backup job to meet a recovery point objective (RPO) specified for the backup job is presented. A method generally includes estimating resource utilization at the source system expected during a plurality of time periods based on historical resource utilization by jobs executed on the source system. The backup system estimates a time required to complete the backup tasks during each time period on the source system based on the estimated resource utilization for each time period and historical backup performance data. Upon determining that the estimated time required to complete the backup tasks for one or more of the time periods meets the RPO, the backup system schedules the backup tasks to be executed during a time period of the one or more time periods with the lowest estimated resource utilization.

Embodiments for an approach to resource optimization during consistency group formation associated with a global mirror environment is provided. The approach detects when a primary volume associated with the consistency group has completed transmitting its out-of-sync (OOS) data towards its associated secondary volume. A command is sent to create a next consistency group sidefile so further writes can be sent to the sidefile rather than queueing at the primary volume. The approach repeats this process for each primary volume associated with the global mirror environment until all primary volumes are complete. Commands are sent to disable writes to the associated sidefiles and to merge the data stored in the sidefiles into normal cache as the next consistency group becomes the current consistency group.
