12. *Third-party marks and brands are the property of their respective owners. Copyright © Intel Corporation 2004 Volume 1 Snapshot -- a set of incremental pointers of a volume at a point in time. It allows the users to “roll back” the volume to its state at a certain point in time in the past. Features: Can be automated on a per volume basis with retention policies, etc. No limit on the number of Snapshots Can be mounted as Read-Only volumes for backup or single file restore purposes. Benefits: Near instantaneous retrieval of data compared to tape backup solutions. Facilitates recovery to pre-error state (compared to mirroring, which would mirror all errors) Minimal storage space required by incremental pointers to only delta (change) blocks. Some competitors require large “set aside” storage to be pre-allocated for snapshots. LeftHand allows Snapshots to start small and “Autogrow” as needed. 1:00 PM 2:00 PM Active File System Snapshot 1(preserves original file system volume) Snapshot 2 Rollback Volume: Volume reverts back to the point in time the snapshot was created Volume 1 Stores changed blocks only Configurable Snapshot Package

Copyright © Intel Corporation 2004 Remote Data Protection Package – “Killer App”  No distance limitations with IP protocol  Affordable due to Ethernet underpinnings  Can be managed from one location  Easy off-site backup management, either real-time or via snapshot  Remote Data Protection replicates at the block level – Efficient for whole volume replication  Remote Data Protection replicates incrementally – After the baseline level snapshot, future snapshot layers to be copied only contain incremental data.  Remote Data Protection is efficient in dealing with network glitches – Copy is done in10% increments. If the network failed in the middle of a large volume copy, the resumed copy will start at the closest 10% mark.  Remote Data Protection can be used to create “in Place” copies of volumes – Can be used to facilitate development, testing, or Data Mining efforts  Remote Data Protection supports multiple sites replicated to a central site – Can be used to facilitate centralized backup  Remote Data Protection can replicate bi-directionally between 2 sites. Allows for a company with multiple locations to provide Disaster Recovery for each site Site A Site B Remote Data Protection provides cost-efficient site diversity

Copyright © Intel Corporation 2004 Volume 1Snapshot 1 Secondary Snapshot 1 Secondary Volume 1 When a user manually chooses to create a Remote IP Copy or initiates a schedule to do so, the system goes through the following 4 step process… 1.System takes a snapshot of the Primary volume 2. System creates a secondary volume and an empty snapshot of the backup volume 3. System copies data from the primary snapshot to the Remote IP Copy snapshot Production Site cluster Remote or DR Site cluster Wan or Internet Link Snapshot 2 Secondary Snapshot 2 4. When a schedule is present, subsequent Snapshot layers are created and replicated to the remote site to “catch up” the Volume In the Case of a disaster, one of the Secondary Snapshots can be “rolled back into the Secondary Volume and then put into production Disaster!!!
