2. 2 Backup and Restore Types Network backups for ESX – Direct to target Network backups for ESXi –vRanger as a Proxy LAN Free or Fiber/iSCSI backups for ESX and ESXi –vRanger proxy on Physical server attached to VMFS Datastores Hot Add backups – vRanger installed on a VM

3. 3 vRanger Pro 5.2 Architectural Options Network Based ESX Hosts use direct to target ESXi Hosts use vRanger server as proxy LAN Free ESX(i) Hosts use physical vRanger as proxy Proxy server has storage connections to VMFS and repository Hot Add vRanger must be installed in a VM vRanger ESX(i) Host must see storage for all VMs to back up VMVM Source VM Hot Add

4. 4 ESX Network Backups

5. 5 ESX Network backups Benefits Simplest way to deploy vRanger with ESX hosts Uses Direct to Target Works with vRanger as a VM or as a physical server Generally works well in small environments and with dedup appliances for repository Considerations Service Console NIC can be limiter Consider using 2 nd SC NIC to isolate backup traffic Multiple concurrent jobs can saturate moderate storage devices (sata disks, controllers, interfaces) – use resource manager to adjust # of tasks Performs better with a larger number of ESX servers that are less VM/data dense

6. 6 ESXi network backups vStorage API running from vRanger server connects to ESXi host and requests a snapshot to be made Data travels out from ESXi host to vRanger uncompressed, vRanger compresses, and sends it to the repository

7. 7 ESXi Network backups Benefits Simplest way to deploy vRanger with ESXi hosts Works with vRanger as a VM or as a physical server Backups are streamed to vRanger for white-space removal and compression, then sent to repository Generally works well in small environments Considerations ESXi Mgmt NIC can be limiter Consider using 2 nd Mgmt NIC to isolate backup traffic The entire VM must be copied each time to vRanger No Direct to Target

8. 8 LAN Free (Fibre or iSCSI) backups vStorage API running from vRanger server connects to ESX(i) host and requests a snapshot to be made vStorage API running from vRanger server reads VM disks and writes archives to repository. vRanger acts as proxy.

9. 9 LAN Free (Fibre or iSCSI) backups Benefits Leverages investment and performance of your SAN Isolates backup traffic to SAN Performs very well Can add additional HBAs or NICs to backup server to increase performance and scalability Considerations Do NOT initialize the VMFS datastores from your vRanger server! Scalability will also depend on # of cpu cores, amount of memory, and bandwidth to repositories.

10. 10 Hot Add backups VM Source VM vRanger server connects to ESX(i) host and requests a snapshot to be made. vRanger server reads VM disks, removes whitespace, performs compression and/or encryption, and writes archives to repository.

11. 11 Hot Add backups Benefits Simple to deploy and configure vRanger server must be a VM Read speeds @ native VM performance Considerations Disable auto mount on vRanger server Add 2 nd SCSI controller to VM Scalability will also depend on # of cpu cores, amount of memory, and bandwidth to repositories.
