Thanks Tony for sharing this and looking forward to this discussion....

I am actually working on a project where have to enable Tlog backups on one of my system.The system is quite heavily used so have to first gather information on what average per day t log size can get to so as to ensure we have enough disk space to accommodate it comfortably and even little bit worried on performance impact as well but then point in time recovery is only available when we enable this option so don't have any choice really....
