Estimate-preUpgrade-backup

This utility prints the estimate of pre-upgrade backup disk size and actual disk size used after backup has taken to compare the correctness of the estimation.

Usage

• Executing the binary without passing any parameter will print Pre-backup estimated disk size
• Executing the binary with actual parameter will print Pre-backup estimated disk size and Post-backup actual disk used

An example is provided below:

[root@lab-test-spoke2-node-0 core]# ./main actual
