Dell EMC Avamar for VMware 19.7 User Guide
VM snapshot fails backups due to incorrect pre-evaluation of available space
The "snapshot_max_change_percent" flag tells the proxy to pre-evaluate free datastore space to ensure that there is enough storage for the VM snapshot. The default value is set to 5%. If the proxy incorrectly fails the backup due to the perceived lack of storage, override the value by either changing the percentage to "0" by the user of the policy, or by permanently overriding the value in the proxy command file.
To permanently override this check in the proxy, log in to each proxy, modify the file /usr/local/avamarclient/avvcbimageAll.cmd to include the line:
-- snapshot_max_change_percent=0
