From the above output, 651103716 KB data changes in 20th snapshot and 417218140 KB data changes in 27th snapshot.
What will happen when next snap schedule on Apr-3rd?
After auto deletion of 20th snapshot based on retention, will there a data changes in 27th snapshot? or data changes only will be on new snapshot?
