You can enable the standard logs in the Preferences -> Advanced:
Enable the “Debug mode logging” for the verbose version of the logs. For the most verbose level of the logs you have to enable the IMAP transactions logs but be careful: it can quickly fill your memory (it creates a lot of data).
To See the standard Logs
Open the Utility -> Logs window, they will browse in that window:
Before closing it remember to disable the Logs in Preferences otherwise it will go ahead to store data in that box.
To See the Console Errors
Sometimes an App can crash and we need to understand what happened before helping you. You should see the logs in the OSX Console, copy it and send them to us.
Open it (Application -> Utility -> Console) and look for the BackUp Gmail lines:
February 27, 2011 was a Black Sunday for all Gmail users and lovers like me. Some Gmail accounts lost everything: messages, address books, contacts, etc. 0.08% of all total users (according to Google’s official version) had problems.
I was lucky enough not to be among them, but the event was enough for me to lose the blind faith that I had in Gmail. And so I began to start thinking about solutions to the problem of creating an incremental backup for Gmail that would be lightweight but effective.
That’s how I got started with analyzing the problem, starting with Gmail IMAP Extensions. Their IMAP extensions have all the functions and properties needed to obtain a backup that can guarantee complete restoration of all data (folders, threads, etc). I wanted a lightweight, silent, reliable app, something that worked in the background in classic Mac style, “like the Time Machine“. Something simple to configure, without shell commands or cronjobs to set-up, and with the principle that once you’ve installed it, you can forget about it.
That’s how BackUp Gmail first took shape in my mind …
