I have been having issues backing up my database for some reason, which I noticed when I tried to manually back it up before upgrading to 9.5 yesterday. It actually turns out that the auto backups, which were set to run nightly at 2am, had actually been failing for the past two weeks almost with an "unable to connect to database" error in the database backup log. The JSS has been functioning fine though without any issue since then, so I wasn't sure why the database utility would have trouble backing it up. Running Mavericks 10.9.5 and OSX server 3.2.1 with JSS 9.5 currently (first ran into issue with 9.4 yesterday).
I also kept getting the following error when trying to back it up:
Warning: Using a password on the command line interface can be insecure.ERROR 2013 (HY000): Lost connection to MySQL server at 'reading authorization packet', system error: 0
Restarting the mysql server from the database utility seems to let the backup run properly after, but that error has appeared fairly regularly and I don't know why.
Also, going to be adding a feature request shortly to notify admins if database backups are failing...wasn't a great feeling when I thought my last resort solution was to restore from a backup...only to find there were no current backups.
