Veeam BR – Backup Mode I/O Consideration

If you want to use Veeam BR as you backup and recovery software in your virtual environment, you have to consider the below I/O table about your backup mode and choose best backup mode according to your backup infrastructure and your company backup policies:

Backup Mode I/O Cost
Incremental Backup 1x I/O on target (write for each changed block)
Reversed Incremental Backup 3x I/O on target (write + read + write for each changed block)
Active Full Backup 1x I/O on target (write for each block)
Synthetic Full Backup For Incremental Backup Mode 2x I/O on target (read + write for each block)
Synthetic Full Backup For Incremental Backup Mode With Transform 4x I/O on target (read + write + read + write for each block)

Reversed Incremental will reduce your storage cost but increase I/O cost.
