  • Page 2: Executive Summary

    Executive Summary Protecting data across all corporate locations is critical for business, legal and regulatory compliance purposes in today’s information age. Too often, business critical data at remote locations is inadequately protected, exposing the business to the risk of lost data and lost productivity. A study conducted by industry analyst Enterprise Strategy Group found that the top three IT priorities for remote office / branch office (ROBO) locations were driven by business priorities: Improve information security, ensure regulatory compliance, and improve disaster recovery...
  • Page 3 The HP Vision for ROBO based data protection is that backup data should be accessible wherever it is required which in some cases requires it to be in 3 locations as well as on physical tape. This gives maximum flexibility in restore options or DR options. When managed through a single backup application this allows the personnel with relevant expertise to recover the data from multiple locations , be it recovering data at the ROBO site from the ROBO appliance but managing the recovery from the data centre or regional data centre, or even recovering at the ROBO site itself if the...

  • Page 4: Scenario Summary

    Scenario Summary Scenario 1 Scenario 2 Scenario 3 100+ ROBO’s with 200-500GB full backups 200+ ROBO’s with full 100+ ROBO’s with backup size of 100GB PLUS Typical sizing 200-500GB full & incremental backups Up to 4 regional data backups of 10% centres with 7.5TB to 300TB backups requiring DR solution...

  • Page 5: Introduction: Issues Associated With Remote Office/Branch Office Backup

    The key learnings from a study of these scenarios are:-  Using physical tape at ROBO’s and performing daily off-siting of physical media will become a thing of the past, physical tape will be replaced by WAN based backup or a HP virtual tape libraries so that the whole process is automated and managed from a regional centre or main data centre.
  • Page 6 Errors and failures not always accurately diagnosed. Low restore success rate at a local level was probably a major issue.  If the backups were large or slow and only a single backup device was available – the backup window could be large and extend into the normal business hours affecting critical business applications.

  • Page 7: Solution Scenarios

    Solution Scenarios The scenarios discussed below cover a wide range of implementations that are possible using HP Virtual Tape Libraries and HP Data Protector software, from a small business that has several outlets to a major corporation that has hundreds of remote/branch offices, several regional data centres and multiple main data centers.
  • Page 8 The key benefits to the customer of this solution are:- Object consolidation using synthetic full backups to minimize WAN traffic  Variable Retention policies. Short term on D2D, Long term on tape for archive.  Fast recovery from D2D4000 with NAS* emulation ...

    Scenario 2 –Low Bandwidth Replication using HP D2D and HP Data Protector for up to 24 remote sites Figure 3 : End to End Low Bandwidth replication solution with regional centre consolidation, all under HP Data Protector Control Key message: Backup Consolidation & Cost effective Disaster Recovery for larger ROBO’s In this next example the volumes of data on the remote sites are much larger;...
  • Page 10 The D2D4112 as well as acting as a replication target for the ROBO sites can also act as a source for backups from the regional centre servers as can be seen in Figure 3. This solution provides robust disaster recovery, should a total disaster occur at the source (ROBO), the data is safely already offsite at the target ( regional data centre).

  • Page 11: Scenario 3 -Low Bandwidth Replication Using Hp Vls And Hp Data Protector For Regional Data Centers

    Scenario 3 –Low Bandwidth Replication using HP VLS and HP Data Protector for Regional data centers. Figure 4: Regional data centre to Main data centre End to End replication with HP VLS all under HP Data Protector control Key Message: Scalability, Consolidation and Data Centre resilience In this scenario the volumes of data involved at the regional data centres are significantly high and the need for scalability paramount.
  • Page 12 Replicated cartridges from the regional centre arriving at the VLS target in the main data centre send an Email on an hourly basis to the Data Protector Cell manager at the main data centre. Data Protector scripts then import these newly replicated tapes into the backup catalog at the main data centre to allow easy access to replicated data in the event of disaster recovery being necessary for the regional data centre.

    Summary The three scenarios described above give an insight into the various ROBO & regional data centre DR deployments possible using HP storage components:- HP Data Protector product features ( synthetic full backup, Object copy, automated tape  importing etc) ...

  • Page 14: Glossary Of Terms

    Glossary of Terms HP StorageWorks Sizer Tool This freely available tool http://www.hp.com/go/storageworks/sizer allows users to specify backup capacities, retention schemes, data change rates, replication window, link speed etc and calculates likely backup storage capacity required, VTL model required, deduplication ratios, time to replicate ( if link speed specified), link bandwidth required ( if replication window specified).
  • Page 15 In-Line ( HP Dynamic deduplication) This is where the deduplication process takes place REAL TIME as the backup is actually taking place. This is the technology used on HP D2D devices. Post Process ( HP Accelerated Deduplication) This is where the deduplication process takes place AFTER the backup has landed on the device to ensure deduplication does not affect backup performance.
  • Page 16 HP Data Protector Cell Manager The Cell Manager is the main system in the cell. The Cell Manager: • Manages the cell from a central point • Contains the IDB ( Internal Data Base) The IDB contains information about backup details such as, backup durations, media IDs, and session •...
  • Page 17 A front-end script will handle the “notification” and feed a “incoming” queue. This frontend is depended on the device (VLS – email processing, D2D XML polling). The backend processes the incoming queue and distributes the media to import to the available devices.

    Appendix A – HP VTL Family with Deduplication and Low Bandwidth replication Figure 5: HP Virtual Tape Library portfolio with Deduplication and Low Bandwidth replication The above figure shows the complete range of HP Virtual Tape Solutions. The D2D2500 is best suited for the most remote offices, the D2D4112 offers major benefits in consolidation by being able to support up to 24 remote D2D2500’s.

  • Page 20 Figure 7: HP Data Protector Synthetic full backup explained HP Data Protector software offers an advanced backup solution called synthetic full backup. This solution enables you to create synthetic full backups and virtual full backups with an operation called object consolidation allowing implementing an incremental forever backup strategy. The incremental forever paradigm means that except for the first backup where a full backup is performed, only incremental backups are executed.

    Appendix C – Deduplication is the enabler for Low Bandwidth replication. Although HP D2D & VLS devices use a different implementation for deduplication both technologies detect unique data and pass that unique data to the replication engine.
