I just found a problem with restoring logs that have recent activity views - an error was being reported (and the log was not restoring):
"action (course-recent) unknow. Not restored"
for module = course & action = recent.
I just added in a new case in restore_log_course in backup/restorelib.php for "recent" which fixes the problem.
I commited it to HEAD & will leave it up to you to whether it should be merged into 14_STABLE or whatever.
