I am using BackWpUp for the last year or so. It has worked perfectly fine in the past.
In the last two weeks, I have got errors twice in a weekly file & database backup job that I have scheduled. Occasionally I do get errors and I ignore them because they never repeat, but this time the same error has happened twice in two weeks, hence thought of posting the error here.
I see the following error in the logs (I am using latest BackWpUp 3.1.2):
[01-Jun-2014 02:22:30] WARNING: Result of table check for wp_options is: 3 clients are using or haven't closed the table properly
[01-Jun-2014 02:22:30] ERROR: Result of table repair for wp_options is: OK
[01-Jun-2014 02:22:30] WARNING: Result of table check for wp_posts is: 1 client is using or hasn't closed the table properly
[01-Jun-2014 02:22:30] ERROR: Result of table repair for wp_posts is: OK
Also, there is another minor issue I wanted to raise. Sometimes (rarely), Dropbox authentication will fail on 1st attempt and succeed on 2nd attempt. However, BackWpUp logs the failure as an error. I suggest to log an error only if all authentication attempts (upto maximum no. of tries) fail. For intermediate errors, an INFO message can logged.
