© 2006 IBM Corporation IBM Tivoli Storage Management 2 TSM for Copy Services Content  Extended snapshot support to applications on Windows –Add VSS snapshot support for MS Exchange Server  Support snapshot providers for MS Exchange VSS –Software snapshots through VSS –Support devices that implement VSS provider interface  It is a new product –Driven by (and also prerequisite) IBM TSM for Mail (DP for MS EX)  MS-SQL Support planned for TSM V5.5  IMR for Exchange planned for TSM V5.5  FS-Backup planned for TSM V6.01

© 2006 IBM Corporation IBM Tivoli Storage Management 3 What is VSS ?  The Volume Shadow Copy Service (VSS) provided with Microsoft Windows Server 2003 is an enhanced Storage Management feature that provides a framework and an API that enables the creation of consistent point-in-time copies of data known as shadow copies.  The VSS service enables the interoperability of third-party storage management programs, business programs, and hardware providers in order to create and manage shadow copies.  Several features in Windows Server 2003 already use the Volume Shadow Copy Service, such as Shadow Copies for Shared Folders and Backup.

© 2006 IBM Corporation IBM Tivoli Storage Management 6 Functional Objectives  Fast Backups - Perform on-line backups of the Exchange Server at snapshot speeds.  Off-loaded Backups - Off-load the backup of data to the TSM Server storage pools to another machine.  Fast Recovery - Perform very fast restores from Exchange Server backups. –Restore from local disk avoiding media mounts –Restore through volume snapshot  TSM Management of Snapshot Backups – Apply TSM policy to control number of snapshot versions and automatically release/reuse disk space when version limit exceeded  Integrated User Interface - Integrate the snapshot operations and legacy backup API operations into the same user interface.

© 2006 IBM Corporation IBM Tivoli Storage Management 12 Exchange VSS Support Characteristics  Single command-line interface (CLI) for performing legacy and VSS snapshot backup, restore, and query operations  Single graphical-user interface (GUI) for performing legacy and VSS snapshot backup, restore, and query operations  Support for both Hardware & Software VSS providers –Those that strictly adhere to Microsoft VSS provider requirements  Operate in a clustered Exchange environment

© 2006 IBM Corporation IBM Tivoli Storage Management 13 VSS Backup Functionality  Backup types: FULL, COPY  Backup granularity is at the "Storage Group" level.  Backups are managed through TSM Server policy.  Backups can be stored on local disk, the TSM Server, or both –specify different policy settings for each storage location –specify different policy settings for different backup types (Full, Copy)  Data movement to TSM Storage can be off-loaded to a secondary machine –requires a VSS hardware provider that supports transportable shadow copy volumes

© 2006 IBM Corporation IBM Tivoli Storage Management 14 VSS Restore Functionality  Restore granularity is at the storage group or individual database level  Standard Restore paths for VSS backups –VSS Restore - Restore from TSM Server storage –VSS Fast Restore - Restore via file copy from mounted shadow copy image  Additional special Restore paths developed by IBM for SVC –VSS Instant Restore – FlashCopy shadow copy image to production volume –Specifically for IBM SAN Volume Controller (version 2.1 or later) –Competitive Advantage

© 2006 IBM Corporation IBM Tivoli Storage Management 15 Supported Providers  All Providers (including DS4000, DS6000, DS8000, SVC, other vendors, …) on the Microsoft website are supported  IBM’s lab testing included: System provider IBM SVC IBM DS4000 IBM DS6000 IBM DS8000 IBM N-series / NetApp

© 2006 IBM Corporation IBM Tivoli Storage Management 16 Benefits of TSM for CS  Fast non-disruptive Backups –Perform on-line backups of database applications at snapshot speed with virtually zero impact to the application. –Transfer data to the TSM Server storage pools from a secondary machine.  Fast / Instant Recovery –Restore from local disk avoiding media mounts –Restore through volume snapshot  Integrated Management of Backups –Support multiple persistent snapshots –Integrate snapshot operations and legacy backup API operations –Manage both through TSM server policy
