VERITAS Confidential Agenda Disaster Recovery Concepts Backup – Last Line of Defence Enhancing Backup with Replication Remote Site Replication and Mirroring Clustering for Disaster Recovery Questions

VERITAS Confidential Recovery Point Objective (RPO) – Point in time to which applications data must be recovered to resume business transactions Recovery Time Objective (RTO) – Maximum elapsed time allowed before lack of business function severely impacts an organization Disaster Recovery Concepts DaysMinsHrsWksSecs Recovery Point MinsDaysHrsSecsWks Recovery Time

VERITAS Confidential “Far Enough” away –How far away from the main site? –What resources should it have? Site Strategies (Hot, Warm, Cold) Considerations –Fault zones –Flood plains –Power grids –Climate zones –Locality relative to other sites (e.g., airport) –Remote customers and employees Choosing a Recovery Site

VERITAS Confidential Backup – Your last line of Defense Redundant systems replicate user errors, viruses and data corruption System or component redundancy (RAID, mirroring) cannot replace backup Backup tapes may represent the last valid copy of data Backups are your last line of defense against total data loss

VERITAS Confidential Enhancing Backup with Replication

VERITAS Confidential Replicating the Backup Catalog server –Shave hours off a tape restore strategy –No need to re-catalog tapes –No need to rebuild the backup/restore server –Tape restores can begin immediately Backup Tape Copies Sent to Offsite Site ASite B Backup Clients Backup Master/Media Server Replicate Backup Catalogs Replication-enhanced Backup

VERITAS Confidential Remote Site Replication and Mirroring

VERITAS Confidential Replication and Mirroring Key Requirements… Must be “far enough” away No windows of data corruption at secondary Synchronous Asynchronous Recovery Point MinutesDays Hours SecondsWeeks

VERITAS Confidential Strengths Maximum data currency (RPO) Data available immediately at secondary (RTO) Weaknesses Potential to impact application performance Data writes lag by network latency Write commit latency across nodes Primary Site Secondary Site Synchronous Replication

VERITAS Confidential Strengths Maximum performance May have less application impact Data available immediately at secondary (RTO) Weaknesses Secondary may lag primary (RPO) Potential for data corruption (not a weakness for VERITAS) Primary Site Secondary Site Asynchronous Replication

VERITAS Confidential Secondary Site Application Volume Manager SAN Fabric Lower hardware costs –Groups physical disks into logical volumes –Hardware Independence, Greater IT productivity –Simplified administration of heterogeneous environments –Proactive management of applications Increased application ROI Can mirror over SAN distances Primary Site Logical Volume Management Remote Mirroring

VERITAS Confidential Clustering for Disaster Recovery
