This report tracks the amount of data changed on virtual disks to find VMs that grow too fast.
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.
The details table provides information on total and daily amount of changes for each VM.

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 on target repositories. This report helps you assess future needs for repository free space.
Report Parameters
Scope (VMware VM folders): defines a list of VMware 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 Business View groups to analyze in the report. The parameter options are limited to objects of the “Virtual Machine” type.
vCD object(s): defines Virtual Cloud 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.
