How to BOOST Veeam Backup Performance by 50% with EMC DataDomain

Servers, Storage and Networking | Posted on November 5, 2015

See how full backup files can be created without physically moving the entire data set into the file, but rather by synthesizing them from existing data. Resulting in faster, more efficient backups.

Veeam Backup and Replication burst onto the scene a few years ago to solve a serious problem concerning backup of virtual machines (VMs). Traditional backup software either couldn’t backup VMs or took half an eternity to do so. Veeam fixed that and rapidly gained a reputation as a go-to platform for virtual backup of VMware and Microsoft Hyper-V platforms.

But rising data volumes are overwhelming backup applications

According to the Digital Universe study by IDC and EMC, 4.4 zettabytes (ZB) of data was created, replicated and consumed in 2013 with 44 ZB predicted by 2020. As a result, virtual backup windows have lengthened so much that many stretch into the next production day.

This challenge gave rise to a partnership between Veeam and EMC DataDomain to greatly reduce the quantity of data that has to be backed up. Compression technology and deduplication technology built into EMC Data Domain Purpose Built Backup Appliances (PBBAs) minimizes the amount of disk space needed for virtual backup.

How to minimize disk space needed for virtual backup

It is commonplace for the same document to reside multiple times on many different servers, desktops and laptops across the enterprise.  If the boss sends a video or presentation to all personnel, for example, it can end up backed up hundreds of times. The result is escalating storage requirements.

The situation is worsened in virtual environments. The process of virtualization generates a great many files which are repeatedly generated by the hypervisor, copied and then retained for long periods. Regular backup software would simply dump these again and again onto the backup target. EMC Data Domain, however, filters out these duplicates, thereby alleviating storage stress. As backups are being fed onto the PBBA, EMC DataDomain reviews data sequences for redundancy. These sequences of data are compared to others and only unique segments are stored on the target appliance.

New full backup files, therefore, can be created without physically moving the entire data set into the file, but rather by synthesizing them from existing data. This results in faster, more efficient backups that enable lower recovery point objectives (RPOs), improve recovery time objectives (RTOs) and lower exposure to data loss.

Turbocharging Virtual Backup

While this factor alone makes virtual backups far more manageable, Veeam now supports EMC DataDomain BOOST technology to speed backups even further. This is achieved by transferring much of the deduplication workload from the backup target to the backup server.

When deduplication is done at the target, all data – including the many duplicate files – have to be transferred across the network to the PBBA where the data will be stored. Once the data has been transferred to the device, it then compresses the data and weeds out the duplicates before storing it. Source-based deduplication, on the other hand, sifts out the duplicate files before they get onto the network.  As well as minimizing storage demands, this greatly lowers bandwidth requirements and shortens virtual backup windows.

Veeam and EMC DataDomain BOOST

Twinning up Veeam and EMC DataDomain BOOST, then, splits the deduplication workload between the source and the target. By doing so, backup performance is raised by up to 50%, full backups are created ten times faster, server overhead drops and the impact on the network is slashed by at least 80%. This makes EMC Data omain with BOOST the ultimate backup target for Veeam Backup & Replication. Additionally, this technology helps IT to consolidate all data protection workloads on a single system for backup, replication and disaster recovery.

This powerful technology combination also decreases hardware requirements. Instead of having to feed backup data to and through backup servers, an EMC Data Domain PBBA interfaces directly with Veeam, thereby eliminating any need for backup servers.
