VM Change Rate Estimation

This report predicts the number of changed blocks (measured in GB) for virtual disks based on virtual machines write rate. The report analyzes rates at which data was written to virtual disks during the selected reporting interval, and displays top N VMs that grew faster and slower than other VMs.

  • Top 5 VMs with Largest Change Rate (GB) chart shows 5 VMs with the greatest amount of changed blocks within the reporting period.
  • Top 5 VMs with Least Change Rate (GB) chart shows 5 VMs with the least amount of changed blocks within the reporting period.
  • Details table provides information on the total change rate and the hourly, daily or weekly change rate (depending on the reporting interval).

Click a VM name to drill down to change rate statistics for each VM disk.

Use Case

To perform incremental backup, Veeam Backup & Replication needs to know which data blocks have changed since the previous job run. The number of changed blocks reflects the amount of data written to the virtual disk.

Veeam Backup & Replication gathers this information to calculate the amount of new data that needs to be backed up. The more changes occur on the virtual disk, the larger amount of space is required to store data in backup. By estimating the change rate, the report helps you assess future needs for repository space.

Report Parameters

Scope (VMware VM folders): defines a list of VMware vSphere folders to include in the report (applies to VMware vSphere environments only). VM folders view is an alternate way to present the virtual infrastructure. If VMs in your infrastructure are grouped into folders according to their profile, you can limit the report scope by specifying the necessary folders only.

Scope (VI): defines a virtual infrastructure level and its sub-components to analyze in the report.

Business View object(s): defines Veeam ONE Business View groups to analyze in the report. The parameter options are limited to objects of the Virtual Machine type.

vCD object(s): defines vCloud Director components to analyze in the report.

Interval/Start Date - End Date: defines the time period to analyze in the report.

Top N: defines the number of top VMs that will be included in the report.

Show VMs with no changes: defines whether VMs with no detected changes must be included in the report.
