Goal of Performance Benchmark
4 4 INF-BC02891 - Pushing the Backup Performance Envelope
Goal of Performance Benchmark
Evaluate performance characteristics of VADP
• Adjust the variables for maximum backup throughput • Adjust the variables for minimum intrusion to ESXi
Test drive underlying infrastructure performance
Obtain real world performance numbers
Develop VADP best practice guidelines

An Introduction: vStorage APIs for Data Protection
6 6 INF-BC02891 - Pushing the Backup Performance Envelope
vStorage APIs for Data Protection (VADP)
• Supports ESX 3.5 U2 (and later)
Introduced with vSphere 4
Change Block Tracking (CBT) provides true incremental backups
• Requires no backup software on virtual machines
Very simple implementation

A Closer Look
12 INF-BC02891 - Pushing the Backup Performance Envelope
Detailed Look at the VADP Snapshot Process
• During backup VADP creates snapshot
– VSS provider flushes OS buffers within VM
– Snapshot created, VMDKs are frozen
– Redo log created – all writes redirected to redo log
– VM data copied to backup storage
– Redo log applied to original VMDKs
– Snapshot released - backup completed
• Why does this matter? – Each step involves significant I/O
– Reducing snapshots per Datastore improves backup performance & reliability
– Incremental backups are quick and reduces snapshot impact

Best Practices in using NBD and 10Gb
• Limit 3-4 streams from a given ESXi system
• The VMkernel (management) port may stay in the default VM Network, rest of the bandwidth complements VM traffic
• Automated in NetBackup using VMware Resource Limits
41
Limit streams per ESXi Illustration

Tip for NetBackup Users!
Best Practices in using NBD and 10Gb
• Backup VMs from multiple ESXi systems to fill the pipe to backup server
– 1 backup from 10 ESXi hosts is better than 10 backups from a single ESXi host!
– Effective utilization of backup server – Concurrency = Smaller backup
window – Lower strain on each ESXi host
– Automated in NetBackup using VMware Intelligent Policies

Best Practices for Hotadd Transport
• Proxy VMs need to access the datastore of VMs being protected
• Recommended to have a Proxy VM at each ESXi system
• Proxy VMs can undergo vMotion or VMware HA
• Proxy VM Operating System – SuSE Enterprise Server for VMware – SuSE Enterprise Server – Microsoft Windows
• Proxy VMs do not need to be backed up, exclude them using Intelligent Policy in NetBackup

• Deduplicated data sent to backup server, reduces network utilization
• NetBackup lets you select deduplication location at Proxy VM level for flexibility

Restore Performance
• Restore process involves more I/O than backup process – Disks (vmdk’s) must be first created as target of restore – Type of vmdk can impact restore speed and I/O required
• Single restore typically won’t saturate restore path – Typically restore performance about half of backup performance – As with backup – balance restores across ESX or Datastore
• Restore performance highly dependent on VMDK format – Thin – faster restores when data is small
percent of VMDK reserved size
– Thick – faster when VMDK nearly full
