I am hoping for some advice on where to turn next please.
We have been using 2.7.1+ (Build 20140626) for a while and except for some recent backup problems has been performing really well.
Our backup problem is:
We have four courses that use four shared Question banks between them, these Question banks are stored at the "System" level for easy access between the four courses (see below - the ones prefixed with "Q30942" are shared):
When we backup one of the related courses it "freezes" part way through the backup process (see below) and because it freezes we don't get any error or debug messages. The courses are not particularly large (the biggest backup is about 60Mb). Of concern is that it has only started happening recently and as no system changes have been made leads me to think it may be volume or size related as we are enrolling more and more students:
If we "un-select" the Question Bank from the backup process (see below) everything works fine:
We have tried every combination of options for the backups and it appears to always comes down to the Question Bank. Doesn't matter if we do it online as a one-off or include it as part of the automated backups (which report the backup as being "unfinished"). I have searched the forums and Trackers and I have seen a few comments about possible problems if the Question Bank is saved at the system level but no references to backup problems or solutions.
Any suggestions or recommendations would be gratefully received as I am at a loss as to what to do next. I am planning to upgrade to the very latest version in the next week or two but I am not hopeful of this solving our problem.
