I would like to see a feature similar to SQL LOG Backup which only copies Exchange Logs and truncates them afterwards.
Regular VM Backup of the whole Exchange Mailbox Role VM is very resource consuming, even with CBT, as there are always many small blocks changed.
With the Snapshot Removal optimizations of vSphere 6 we finally have the ability to do an exchange backup during the day, which lead to service disruption before when removing the VM Snapshot.
But still a simple Log backup (e.g. every hour) would be much more efficient in my opinion. Works great for SQL Servers!
I silently hoped that such a feature would come with V9. Maybe V9.1?
