2 Défis de la protection des données
Protection contre... Les responsables informatiques doivent apporter... Pannes physiques Perte d’équipement ou de site Corruption des données Virus, erreurs humaines Coûts croissants des interruptions de service Protection d’applications métier complexes Objectifs de temps de restauration (RTO) et de points de restauration (RPO) granulaires plus brefs Protection économique des données Customers need protection against data and application loss caused by Physical failures or data corruption failures. A. Physical failures include: Natural disasters that have larger regional impact or just site power outages. Natural disasters such as hurricane, tornado, earth quake, lightening storm, flood, or fire. Man made disasters such as 9/11, or fire, or other human errors that caused outages (Operational errors). Mahcine equipment failures such as disk failure, network failure, server failure etc. B. Data Corruption – application errors that cause data corruption, or virus attacks. C. Increasing business down time cost – business environment that is growing more complex, more critical data and applications to protect. So any downtime impact business in a much larger scale, more costly that the time it takes to recover from outage is ever more critical. IT management is faced with the challenges of 1. Protection for complex business application env. 2. Faster recovery – meaning shorter Recovery Time Objectives (RTO) & Recovery to any-point-in-time, not your last backup that is 12 or 24 hours ago – meaning Granular Recovery Point in Time (RPO) 3. Limited IT budget but want an affordable solution with enterprise class capabilities. Industry study showed: 75% reported serious or catastrophic events as drivers to improve Business Continuity(BC) /Disaster Recovery(DR) capabilities. So what solution is the ideal solution to address customers BC/DR challenges that is affordable and with enterprise class capabiltiies? Let’s discuss EMC RecoverPoint for what it is and what it can do for customers.

Key to determining which replication solution is best for a particular application is a thorough understanding of service levels. Specifically, you will need to balance your requirements for performance, functionality, availability, and economics against capacity needs, bandwidth requirements, and overall total cost of ownership. Every solution will have benefits and risks, and you must balance all of these factors in order to decide the best solution for a given problem.

4 RecoverPoint pour Oracle
Difficultés des clients Oracle Restauration trop longue des bases de données Multiples outils de protection Les boutiques Oracle exécutent davantage qu’Oracle RecoverPoint apporte : Restauration beaucoup plus rapide Outil unique pour protéger TOUTES vos applications Oracle customers struggle with the time to recover Oracle databases as well as the ability to recover the applications the databases support to any point-in-time. 90% of Oracle customers have more software to protect than just Oracle and can benefit from a single solution to protect their enterprise database and applications software at the lowest cost – both locally and remotely Oracle DataGuard has its benefits and some DB admins would never replace it. Assess the situation, then position RecoverPoint either as a single solution or as a complement to DataGuard

5 RecoverPoint : fonctionnement
Protection en local Protection à distance Hôte WAN/SAN RPA RPA (cluster) VPLEX / A / B Here is a quick introduction of RecoverPoint technology RecoverPoint is a SAN based replication solution. It sits between the host and the array by utilizing software embedded in the array which is called the Splitter [CLICK] The splitter copies incoming WRITE commands from the host and sends them to the RecoverPoint Appliance (RPA). The RPA updates a Journal which stores all the changes made to the data. This Journal is the RecoverPoint secret sauce that enables us to recover to ANY POINT IN TIME. When a physical RPA is used, it connect to the VNX via FC. When a virtual RPA is used, it connect to the VNX using iSCSI. The data in the journal is used populate a copy reflecting the selected point in time for recovery or testing. Normally the copy is hidden but acts as a mirror This configuration is known as LOCAL REPLICATION, or LOCAL PROTECTION In REMOTE REPLICATION, the data from the source RPA is sent to a remote target system : over IP or FC, in Sync or Async modes. Note that the virtual RPA has only IP connectivity A system can have local replication, remote replication or both Fichier log Copie locale d A d C d B Copie distante d A d C d B Fichier log

6 RecoverPoint assure la cohérence des données
Saisie des commandes Gestion de la chaîne logistique Gestion de la relation client BD Les applications sont liées entre elles (fédérées). Pour redémarrer des applications, vous devez disposer de toutes les données, pas seulement d’une partie La restauration nécessite la cohérence des écritures dépendantes sur tous les volumes et systèmes Here’s a scenario that illustrates the problem of data consistency among different database applications. A hypothetical organization has a set of applications deployed among several different servers and databases. An order-entry application may be deployed on a high-end server, for example, running UDB. That may feed a shipping application running on Oracle on a UNIX system. Information about orders and shipments might be fed by the SCM (supply chain management) system into the CRM (customer relationship management) system running on SQL Server on a Windows Server system. How does this organization assure consistency among these diverse databases, applications, and servers? One approach might be to create a single, monolithic database environment. This is not optimal for a variety of reasons. Another might be to write “handshake” logic to assure coordination and consistency among applications. This is difficult to do and maintain. Many organizations simply ignore the consistency issue and live with the consequences, which is not optimal if customer satisfaction is important. A RecoverPoint consistency group is a technology that groups together various volumes or LUNs, either on a single system or across systems, so that when they are protected and recovered, they are handled as a group. With RecoverPoint you either get all of the data or none of it—you will never get part of the data. An EMC networked storage infrastructure, meanwhile, can help ensure consistency among various distributed elements of the information infrastructure. EMC can provide a unique enterprise-consistent capability by creating consistency groups across multiple storage systems with a mix of open systems and mainframe, ensuring a consistent view of all your data.

Each approach and its corresponding technologies has its place depending on the business need and cost. Traditionally, businesses relied solely on once-a-day backup routines using traditional tape-based or disk-to-tape-based data protection solutions. But as business requirements are becoming more and more demanding the challenge of resolving corrupted and lost data becomes more and more vital to IT organizations. With the cause being fat fingers, viruses, corruption or data over-runs the IT organizations can no longer rely on backups alone and are complementing backup solutions with data replication technology. There are mainly two options when looking to improve recovery objectives for critical applications: Snapshots enable multiple application restore points – primarily for faster recoveries, but also for use cases such as test/dev, reporting, analysis, and repurposing. Snapshots are made by regularly “syncing” a production volume with a secondary copy and then breaking off the copy for later usage. RecoverPoint’s Continuous Replication enables any point in time recovery – for recovery to the millisecond, using a unique DVR-like rollback mechanism. Continuous replication provides the benefits of near RPO with any-point-in-time replication capabilities, meaning you can restart your application from a fraction of a second before the data corrupted. Continuous replication can significantly enhance your current business and technical operations by providing you with access points to production data; enabling parallel-processing activities like backups, as well as disk-based recovery after logical corruptions; and creating test environments for faster time to revenue for applications. RecoverPoint’s provides the broadest set of native replication capabilities in the market. 8h 12h 16h 20h Sauvegarde quotidienne 8h 20h NIVEAUX DE SERVICE PAR TECHNOLOGIE

8 Exemple d’utilisation de RecoverPoint pour un environnement Oracle
Protection contre les pannes physiques Perte d’équipement ou de site Protection contre la corruption des données Virus, erreur humaine Restauration à un point dans le temps Avec cohérence dans la pile d’application Solution unique protégeant toutes les applications Outils spécifiques aux applications inutiles Production Réplication Réplication Copie distante As Oracle environments scale, many Oracle customers we speak with today need to ensure the fastest and most complete recovery of not just their databases, but the applications themselves, and the middleware which supports them. Oracle software provides technologies for recovery today, such as Oracle DataGuard. However, even these technologies are limited in their ability to recovery not just the database, but the applications that run on them and the middleware connecting them. EMC RecoverPoint allows the use of application-aware recovery software which will simultaneously track every Oracle incoming write before it is written to disk and log this in what we call a recovery journal. This recovery journal is kept on local disk and can be replicated remotely being compressed and de-duplicated to reduce the cost of disaster recovery bandwidth up to 9x. From this technology we can now set more granular recovery points of your Oracle applications to roll them back to any point-in-time needed, and do so using just one tool, vs. combining backups, database replication and other tools.

11 Restauration d’Oracle 10 fois plus efficace
Washington Trust choisit RecoverPoint Défis Davantage de restauration de bases de données Oracle Protection des bases de données physiques et virtuelles Actions Déploiement d’une solution RecoverPoint pour la restauration des bases de données à un point dans le temps pour une protection continue They run a very small IT department with one IT person per 100 employees and keeping up with growth of the business was becoming a major challenge. To improve their IT efficiency the company built a private cloud environment on EMC VNX unified storage and Vmware. Their virtualized environments include Oracle as well as SQL Server, and Exchange, as well as test and development servers running Oracle core-banking applications. Washington trust also deployed RecoverPoint to replicate business critical applications such as Oracle core banking and Exchange between two EMC NX systems 50 miles apart. The result is far more efficient protection than using Oracle software features alone. They were only able to recover back to a point in time that at best was 45 minutes before the outage that occurred before moving to RecoverPoint. Now with RecoverPoint they can bring their Oracle databases back to any point in time at 2-4 minute intervals. This leads to 9X more efficient recovery being able to bring Oracle back to a closer point in time before a disaster for faster, more accurate recovery.

This allows users to connect to any of the hosts and have access to a single set of data. Oracle ASM is a volume manager and a file system for Oracle database files that supports single-instance Oracle database and Oracle RAC configurations. The ASM volume manager functionalty provides flexible host-based mirroring.

This is a powerful enhancement from an availability perspective, but very few people implement this option. The reasons that it is not popular centers on the substantial complexity of the configuration and ongoing management of all the nodes’ storage, as well as the fact that user SANs have to traverse the two sites, making for a much more complex and expensive networking infrastructure.
