Running and Scheduling Backups

Key Commvault Terms Virtual Server Agent (VSA) – Agent installed on Windows server that backs up VMware VM via VADP API. Vmware vSphere server – Physical host running VMware ESXi virtualization hypervisor Vmware vCenter– VMware management server

Vmware backup Browse & Restore Or Automated Restore Virtual Machine Pool Client Dedupe LAN backup Backup Agent Backup Agent Backup Agent File or App restore Simpana Media Agents Backup Copies Disk Cloud Tape ESX Server Pool Data Store Pool VSA vStorage VADP SAN backup Full VM, VMDK or File restore

How it works VSA talks to vCenter to trigger backup VM is quicse and snapshot by Vmware Backup Data is transferred to VSA then to MA vCenter VSA ESX MA

VMware Protection Architecture – SAN Mode Management Communication LAN vCenter server VSA Disk Library ESX Servers CommVault Win Media Agent VMware Protection The core component behind protecting VMware environments are the vStorage APIs for data protection. As of SP4b we have upgraded the VDDK (virtual disk development kit) which is a component of VADP to 5.0 which was released with vSphere 5. VMware also recently released the VDDK 5.0 u1 which contains some fixes to help alleviate some of the issues with residual consolidate helper snapshots. Some of the key features of VADP are… Faster Backup and Recovery: Eliminate the impact of backup on production servers – The biggest advantage of VADP is steaming disk level backups. No backup of a backup as in the VCB days. Multiple backup options: disk level, file level and volume level allowing greater flexibility in protection policies Fast Incremental Backups: Leverage Change Block Tracking for low impact incremental – No need to scan the entire disk during an incremental backup. The CBT table provides a list of all changed blocks since the last backup. Multiple Deployment Options: Physical / Virtual. SAN, HotAdd and NBD transports. (Explain each) Multiple restore options: Full VM Restore to and Granular File Level Restore from a single pass backup. No restaging on disk required as in the VCB days. Flexible Deployment Options: Deploy in Virtual Machines for minimal additional servers overhead or on physical servers. Multiple Deployment Options: Physical / Virtual. SAN, HotAdd and NBD transports. Embedded Deduplication: Embedded source side deduplication for minimal data transfer at scale for even faster backups lower impact on infrastructure DataStore LUNs Physical Win VSA server SAN transfer mode Backup should be to Disk Library Data Transfer over SAN (FC/iSCSI)

restore Entire VM, single VMDK or single OS file can be restored NTFS, FAT32 and Linux ext3 files can be restored For single-file restore, the backup must be done to a Disk Library first

Other details The VSA is normally installed on the MA so that there is no need for network data transfer between VSA-MA. Multiple VSAs can be installed and used for the same VMware environment
