Solutions for every stage of VMware adoption

– Granular and application consistent virtual machine backup at the guest level – Image-level backup at the ESX Server Service Console level

– Snapshot-based backup with VMware Consolidated Backup (VCB)

Choose traditional or deduplication backup

– Traditional operations deliver VMware protection with disk and tape

– Source-based deduplication reduces impact of backup – ideal for virtual machine backup

Avamar Virtual Edition for VMware

Avamar Server Software Deployed as a Virtual Appliance Industry’s first de-duplication virtual

appliance for backup, recovery, and disaster recovery

– No other VMware backup and recovery product encapsulates both backup and disaster recovery

Leverages existing servers and storage

Avamar VM Operating System

Leverages existing servers and storage

– Can utilize any storage (SAN, NAS, or DAS)

Replication (of applications and storage) eliminates shipping tapes

– Replicate between Avamar virtual machines, or from Avamar virtual machines to Avamar Data Store or other server solutions

Facilitates rapid, cost-effective deployment and return on investment

vStorage APIs for Data Protection

The vStorage APIs for Data Protection enable backup software to protect system, application, and user data in your virtual machines in a simple and scalable way. These APIs enable backup software to:

• Perform full, differential, and incremental image backup and restore of virtual machines.

• Perform file-level backup of virtual machines using supported Windows and

• Perform file-level backup of virtual machines using supported Windows and Linux operating systems

• Ensure data consistency by using Microsoft Volume Shadow Copy Services (VSS) for virtual machines running supported Microsoft Windows operating systems

VMWare Data Recovery

http://www.vmware.com/files/pdf/VMware_Data_Recovery_FAQ_4.21.09.pdf

VMware Data Recovery is a separate product that is built on the VMware vStorage APIs for Data Protection(VADP).

Is VMware Data Recovery the replacement for VMware Consolidated Backup (VCB)?

(VCB)?

VMware Data Recovery is not the replacement product for VCB. Both products will co- exist.

Backup

• Define jobs: select sources, destination, backup window and retention policy

• Disk target – Virtual disks and CIFS share

• Full and incremental backups VM. (Note that after the initial full backups, all other backups are incremental)

Restore

• Full VM restore; create or overwrite entire VM

• Overwrite single disk

• Power on VM after restore

How about NOT doing any backup?
