VADP Snapshot Process VMware creates temp snapshot of VM VSS provider flushes OS buffers in VM Snapshot of VM is taken (vmdk(s) are frozen) (SCSI reservation of LUN) Redo log created all writes redirected to redo log (Redo expanded in 16 MB chunks) VM is backed up Redo log data applied to original vmdk(s) Snapshot released - backup completed Why does this matter? Every one of these steps involves significant amount of I/O Reducing number of snapshots per Datastore improves backup perf & reliability Incrementals are quick and can reduce snapshot impact VM1 VM2 VM3 VMDK VMDK VMDK VMDK VMDK VMDK ESX/ESXi
Redo Log Creation Process VMware rules for creation of new VMDK Empty VMDK is created first Space within the VMDK must be zeroed (mandatory) Data is now written to zeroed space within VMDK 0% Redo log creation follows these same rules Expanded in 16 MB extension each extension must be zeroed Three steps: create, zero, write NOTE: similar process for thin provisioned VMDK creation Redo is a temporary VMDK At end of snapshot redo must be reapplied to original VMDK
Reducing Backup I/O Impact Shorten time backup snapshot is open Configure backup application for optimal performance Result: Snapshots more reliable Overall backup processing faster Higher level of backup success
General Restore Considerations Restore process involves more I/O than backup process Single restore typically won t saturate restore path Slow vcenter can also cause restore performance issues
VMDK Type Can Impact Restore Speeds 0% 100% 100% 0% thin Space not allocated during creation Space is supplied then zeroed out on demand Creation slow if vmdk turns out to be full zeroedthick 100% of space allocated during creation Zeroed out on demand Can be faster than thin especially if vmdk is nearly full eagerzeroedthick 100% of space allocated during creation 100% of disk zeroed out during creation Could take long time (and create lots of I/O) to complete entire process
