Why Snapshots Are Useful for Backup

� Faster backups without taking applications off-line

– Minimal impact to application performance

� Faster recovery time (RTO)

� Easier to realize more recovery points (RPO)

� Minimal downtime for applications

� What types of snapshots are there?

– Split-mirror

– Copy on Write

– Redirect on Write

– Others...



IBM FlashCopy® Technologies

FlashCopy (FC)Full Volume Copies

Incremental FCCopy Changed Blocks since last FlashCopy

Space-Efficient FCCopy to Space-Efficient Target Volumes

� Improved performance of online backups with incremental copies

� Space-efficient targets significantly reduce application storage needs

� Heterogeneous FlashCopy targets with SAN Volume Controller



� Volume Shadow Copy Service - A service that coordinates various components to create consistent shadow copies of one or more volumes.

� Requestor - An application that requests that volume shadow copy be taken. A backup application is an example

� Writer – A component of an application that stores persistent information on one or more volumes that participate in shadow copy synchronization. Typically this is a database application like SQL Server, Exchange Server, or a system service like Active Directory

� Provider – A component that creates and maintains the shadow copies. Examples are the system provider included with the operating system and the hardware providers included with storage Arrays.

� Source Volume – The volume that contains the data to be shadow copied.

� Storage/Target Volume – The volume that holds the shadow copy storage files for the system copy-on-write software provider.

Microsoft Volume Shadow Copy Services (VSS)



Introducing IBM Tivoli FlashCopy® Manager

� Perform and manage frequent, near instant non-disruptive, application-aware backups and restores

� Leverage advanced snapshot technologies within IBM storage systems

� Improve availability of IBM DB2, SAP, Oracle, Microsoft Exchange and Microsoft SQL application data

Key Functionality - Restore

Microsoft Exchange� Snapshot Restore* of Exchange storage

groups � File copy restore of a storage group or

database from a mounted snapshot image

– Restore into a Recovery Storage Group, alternate storage group, or relocated storage group

� Individual mailbox or mail item restore from a snapshot backup

Microsoft SQL � Snapshot Restore* of a full database

backup � File copy restore of a full database from

a mounted snapshot image – To an alternate database name– To an alternate location

IBM DB2 UDB� Snapshot Restore of a Full database � Snapshot restore of one or more database

partitions in the case of a multi-partition database

Oracle� Snapshot restore of a Full database

SAP� Snapshot Restore of a Full database

* As supported by Volume Shadow Copy Services (VSS) provider



Key Functionality – Item Level Restore for MS-Exchange

� Operate on single or multiple user mailboxes

� Select which backup to restore based on: – User name and date/time specification

� Perform recovery of the following mailbox items: – Inbox, deleted items, drafts, junk e-mail, outbox, sent items, journal,

calendar, contacts, notes, tasks, user folders

� Limit the scope of items to be restored based on th e following filters:

– Sender name, subject text, attachment name, folder name, messagedelivery date and time range, message body, all content (searches subject text, message body, and attachment names)

� Supports multiple restore destinations– Original location into original mailbox on original Exchange Server

– Alternate mailbox and folder

– Outlook data (.PST) file



Individual Mail Restore (IMR)

� Faster easier way to recovery

� Item level restore granularity

� Search and Filtering functions

� Restore to Exchange Server or .PST file



Key Functionality – Ease of Use

� Minimize Admin time required to provide highly reliable data protection and recovery

� Designed to install, configure and perform first backup in <= 4 hours

� Familiar, intuitive interface for database administrators

– Reduce learning time, increase speed of operation (productivity), decrease error rates

� Integrated with native administration tools

� Integrated dashboard and reporting tools



Seamless Integration with Tivoli Storage Manager

Additional Granularity

More Backup Options

Multiple Backup

Destinations

More Backup Types



Optional Tivoli Storage Manager Integration

� Tivoli Storage Manager (TSM) integrates seamlessly to provide a wide range of data lifecycle and recovery management capabilities, including:

– Backup/restore

– Hierarchical storage management

– Disaster recovery planning

– Long-term archival

� Scales easily to manage up to 1 billion data object s (including snapshot or FlashCopy images) on a single TSM server

� TSM is installed in more than 20,000 organizations, including 60% of the Fortune 500

� Tivoli Storage Manager version 6 adds greatly enhanced performance, management and data reduction functional ity

Benefits of IBM Tivoli Storage FlashCopy® Manager Support

� Fast, non-disruptive backup – On-line backups of database applications at snapshot speed

– Minimal impact to the application

� Fast/instant recovery– Restore from local disk to avoid media mounts

– Allows extremely fast restore directly from the snapshot using “snapback” to the original location

� Integrated management of backups– Support for multiple persistent local snapshots

– Automatic reuse of local snapshot storage as older snapshot versions expire

� Optional integration with TSM Server– Integrate snapshot operations and API backups with TSM

– Transfer data to the TSM server using a secondary machine for long-term retention and disaster recovery

– Retention policies may be different for local snapshots and copies on TSM server
