18 使用 Live Recovery 還原虛擬機 1 Backup Copy exposed on MediaAgent as NFS Export and mounted to destination ESXi server. 3 Production ESXi Cluster 2 VM configuration and catalog files retrieved and modified to indicate that writes can be made to the NFS datastore Selected VM can be powered on during recovery phase: Running VM can be access during this time. Any changes made will be reconciled to production VM once recovery is complete 4 Mounted NFS DataStore is removed once recovery operation is completed.

19 使用 Live Mount 立即掛載 Production ESXi Cluster Create Live Mount Provisioning Policy: Defines the Live Mount operating parameters and limits within the production environment. Backup Copy is presented as NFS DataStore to ESXi production environment: This is a R/W non-persistent copy in native format. No changes are made to the backup copy. Selected VM powered on: On-demand power on operation, changes to the VM are not altering the Backup Copy data. Mounted NFS DataStore is removed once recovery operation is completed.

20 更多的還原 / 備援選擇 Live File Recovery Live Sync Streaming (Deduplication ) Storage Array IntelliSnap (HW Snapshots) DR Configuration Option Live File Restore allows indexing during protection operations to be turned off Job execution is significantly faster Restore granular objects directly to the VM with no agent required. Supported on Windows (NTFS), and Linux (ext3, ext4, etc.) Live Sync works in conjunction with agentless VMware protection to provide an automated incremental forever approach to recovery and replication of VMs. Works with global deduplication to offer numerous amounts of recovery points.
