CommVault SINPANA 企业数据保护.ppt

在数据管理中，那些问题最令人烦恼？ * 分析问题的原因，典型的IT系统含有：文件系统、邮件系统、数据库、消息系统和WEB。。。 * 在线生产数据的快速增长，导致备份、复制、归档等次级延伸数据更快的增长！会高达10到15倍！ * 传统的管理手段是分散、独立进行的，导致硬件、人员的费用迅速上升。 其他厂商的解决方案就是利用很独立的软件分别来处理不同问题，导致系统越来越复杂！ * * 这中传统的方案中，有很多东西是重复的，占用了大量的系统资源。 * * * The key benefits of our unified approach include lower costs, improved performance, greater scalability and faster and more advanced services and troubleshooting Best in class solutions combined with unification Look at all the common elements collapsed into one common engine: gives us a very unique advantage in the market Will tell you why this translates into more functionality, better performance and lower TCO than competitive offerings in the market * * * * * EMA Report can be found at /forms/EMACommVaultCustomerSurvey * * * CDR is a byte level, continuous capture replication solution. As data is written to the file system, CDR captures and duplicates the byte level changes and places them into a temporary cache. Once that cache reaches a default threshold of 5MB or 15 minutes or another threshold established by the administrator, the changes are sent to the destination. There, a duplicate, up to the moment sequence is replayed. A consistency point can be embedded to mark coherent data sets based on the application. * * 数据级容灾是仅将生产中心的数据完整地复制到容灾中心的容灾方式。数据级容灾是异地容灾的最低级形式，也是最基本的方式，是实现更高级容灾方式的基础。 在灾难发生时，数据级容灾无法保证业务的连续性，仅可以保证数据是可用的，若技术策略选择得当，可以保证业务数据的完整性。对于要求达到应用级容灾和业务级容灾，实现数据级容灾是一个十分关键的基础步骤，但仅通过数据容灾无法满足业务的及时恢复要求。 应用级容灾是指在数据级容灾实现数据可用的基础上，进一步实现了应用的可用性，确保业务可以快速恢复。BOSS容灾系统的应用一般不改变原有的业务处理逻辑，是对生产中心系统的基本复制。 业务级容灾是生产中心与容灾中心对业务请求同时进行处理的容灾方式，能够确保业务持续可用。 * Here we see another possible configuration for disaster recovery. The mail server and database server at the central site are both replicated over the WAN to a server hosting multiple virtual machines. This is a popular configuration where companies can leverage virtualization software such as VM ware to reduce TCO by eliminating costly duplicate hardware at DR site. * * With CommVault Cont
