This module covers TimeFinder local replication benefits and TimeFinder usage as a point-intime business tool. It also provides an overview of TimeFinder’s application set, lists thearchitectural components, and describes the TimeFinder product family.Copyright 2013 EMC Corporation.

TimeFinder is a family of products that enable businesses to provide multiple point-in-timecopies of data to distribute business tasks. This allows for simultaneous action of previouslysequential business tasks. An example is the ability to back up a point-in-time copy of criticaldata while production operations continue on the source data.In today’s IT environments, it is critical to have choice and flexibility when building localreplication solutions in order to match the right product to your service-level requirements.The TimeFinder family of products offers the broadest choice of alternatives, from fullvolume mirrors and clone copies, to space saving snapshot copies. Understanding thefeatures and functions of each of the TimeFinder product family options is imperative foridentifying the appropriate solution.Copyright 2013 EMC Corporation.

Local replication can significantly enhance current business and technical operations byproviding access points to production data for parallel processing activities like backups, diskbased recovery after logical corruptions, and creating test environments for fasterapplication time-to-revenue.The Recovery Point Objective (RPO) is the point-in-time to which systems and data must berecovered after an outage; for example, the end of the previous day’s processing. RPOs areoften used as the basis for the development of replication and backup strategies and as adeterminant of the amount of data that may need to be recreated after the systems orfunctions are recovered.The Recovery Time Objective (RTO) is the period of time within which systems, applications,and functions must be recovered after an outage; for example, one business day. RTOs areoften used as the basis for the development of recovery strategies, and as a determinant asto whether or not to implement the recovery strategies during a disaster situation.Copyright 2013 EMC Corporation.

TimeFinder allows storage-based information users to make more effective use of their mostvaluable resources by enabling parallel information access. In contrast to traditionalsequential information access, TimeFinder eliminates the need to quiesce an application forbackup. This provides tangible benefits to businesses, including accelerated upgrades.TimeFinder enables application upgrades to quickly identify and remedy problems, minimizerisk, and reduce production downtime. TimeFinder eliminates the backup window to highavailability demand systems. TimeFinder can also shorten maintenance windows, minimizeinfrastructure costs, and improve service levels.Copyright 2013 EMC Corporation. Do not copy - All Rights Reserved.TimeFinder Fundamentals7

The TimeFinder family has several different solutions to help you meet your service-levelrequirements, while providing very powerful local replication capabilities.Let’s take a look at what the TimeFinder family delivers. First is its massively parallel highperformance and unsurpassed RPO and RTO with minimal server impact.TimeFinder easily integrates into industry-leading applications, such as Oracle, Microsoft,VMware, SAP, and IBM. This is a result of the integration efforts as well as EMC partnershipswith these major application vendors. TimeFinder is highly recommended with remotereplication solutions like SRDF (Symmetrix Remote Data Facility) to increase applicationavailability and improve test/development capabilities and disaster restart requirements.TimeFinder is the solution Symmetrix customers rely on for business continuity locally, in thearray, and in the data center.Copyright 2013 EMC Corporation.

Each TimeFinder product (TimeFinder/Clone, TimeFinder/Snap) has its own distinctarchitecture and operational characteristics. These attributes are essential when addressingthe wide scope of customer data replication requirements. The components that make upeach TimeFinder solution are listed here. TimeFinder architectural components arepresented at a high level within the next few slides.VP Snap leverages TimeFinder/Clone technology to create space-efficient snaps for thindevices by allowing multiple sessions to share allocations within a thin pool. VP Snapprovides the efficiency of snap technology with improved cache utilization and simplifiedpool management. With VP Snap, tracks can be stored in the same thin pool as the source,or in another pool of your choice.Copyright 2013 EMC Corporation. Do not copy - All Rights Reserved.TimeFinder Fundamentals9

Regardless of the replication technology that is being implemented, the Symmetrix storagearray uses “Track Table” technology that creates a record of the data that has been changed.Using this information is what drives the movement or resynchronization of data back andforth from the source and/or target devices.This technology is employed regardless of whether the data is located in a single array oracross multiple arrays. The Track Table is the underlying enabler for all Symmetrix storagearray-based data-mobility applications and technologies.Copyright 2013 EMC Corporation.

This slide describes the EMC TimeFinder family of products for the VMAX 20K/VMAX and VMAX 40Karrays. The TimeFinder family of products includes Symmetrix local replication solutions designed tonon-disruptively create point-in-time copies of critical data. You can configure backup sessions,initiate copies, and terminate TimeFinder operations from mainframe and open systems controllinghosts using EMC Symmetrix host-based control software.The TimeFinder local replication solutions include TimeFinder/Clone, TimeFinder/Snap, andTimeFinder VP Snap. TimeFinder/Clone creates full-device and extent-level point-in-time copies.TimeFinder/Snap creates pointer-based logical copies that consume less storage space on physicaldrives. TimeFinder VP Snap provides the efficiency of snap technology with improved cacheutilization and simplified pool management.Each solution guarantees high data availability. The source device is always available to productionapplications. The target device becomes read/write enabled as soon as you initiate the point-in-timecopy. Host applications can therefore immediately access the point-in-time image of critical datafrom the target device while TimeFinder copies data in the background.TimeFinder includes the following features: Supports RAID 1, RAID 5, RAID 6, and RAID 10 protection schemes, Provides restore capabilities, Provides incremental re-synchronization between the source and the target, Supports virtual provisioning, and is Tightly integrated with SRDFCopyright 2013 EMC Corporation.

With all the choice and flexibility in making TimeFinder family replicas, how do you knowwhich type to use and when? It is a matter of balancing customer needs and mapping themback to a few key areas: performance, availability, functionality and economics.Pointer-based images are not physical copies of your information; they are logical views ofthe original information based on the time the image was created. Snapshots and snaps arecreated in seconds and can be retired when no longer needed.In contrast to a full data copy, a snapshot uses only a fraction of the original space. Multiplesnapshots can be created to suit the needs of multiple business processes. Secondary serverssee the snapshot as an additional mountable disk volume. Servers mounting a snapshot havefull read/write capabilities with the snapshot data.TimeFinder/Snap multi-virtual sessions allow up to 128 virtual point-in-time copies.TimeFinder/Snap sessions on Symmetrix VMAX 40K systems always use multi-virtual mode.VP Snap leverages TimeFinder/Clone technology to create space-efficient snaps for thindevices by allowing multiple sessions to share allocations within a thin pool. VP Snapprovides the efficiency of snap technology with improved cache utilization and simplifiedpool management. With VP Snap, tracks can be stored in the same thin pool as the source,or in another pool of your choice.Copyright 2013 EMC Corporation. Do not copy - All Rights Reserved.TimeFinder Fundamentals 13
