Virtual Machine Snapshots Captures state and data of a virtual machine at aspecific point-in-timeVirtual disk files.vmdk Allows rapid return to VM state and data (at specificpoint-in-time)SnapshotHandle with Care! Sits in I/O path and causes I/O impactvSphere Consumes disk space: can impact other VMshosted on that storage device High risk of data loss: if you lose the VM, youlose the snapshot No item-level recovery or application-awareness without a backup application5
vSphere Data Protection Advanced 5.8Simple, Efficient Backup and Replication with Predictable RecoveryWhat is it? vSphere Data Protection is a backup andreplication solution for simplifying and optimizingdata protection in vSphere environmentsVDPAdvvSpherededuplicateddataKey Features Agent-less, disk-based virtual machine backups Application-aware, granular, agent-based dataprotection for physical and virtual applicationsVMFS, NFS, VSANstorage End-to-end integration with vSphere andmanaged through vSphere Web Client Single-step recovery Self-service File-Level Recovery Powered by EMC Avamar
Quick to setup, Easy to use Deploy as a virtual appliance Manage backup and replication throughvSphere Web Client Automatic VM discovery Wizard-driven Single-step recovery Self-service File-Level Recovery (FLR)
Application Awareness for Mission-Critical AppsBackup for Virtual and Physical ApplicationsIn VDP Advanced Only Agents for Exchange, SQL, SharePoint Database-level backup and recovery for Exchange, SQL,SharePoint Mailbox-level recovery for Exchange Backup for non-virtualized Exchange, SQL, SharePoint apps Support for MS Exchange DAGs, SQL Server ClustersvSphereVirtualKey BenefitsPhysical New in5.8Application consistencyClient-side deduplicationGranular backup and restoreLog management8

vSphere Replication – How it Works Full/initial Sync– Start fresh or with seed via physical media– Compares disk IDs– Calculates checksum of all blocks at source & target– Exchanges and compares checksums to determine delta– Replicates all changed blocks necessary to align virtualdisks Delta sync– Writes tracked by vSCSI filter driver, which is part of theESX host– Tracks new blocks as they are written– Bitmap of changed blocks is maintained betweenreplications– Each replica corresponds to a lightweight delta– During a sync changed blocks are read and sent to thetarget– No VM stun & very little IO penalty14
