Now this was a head-scratcher: the BackupBuddy settings on 5 of my client websites simply reset for no apparent reason. And that means the websites were not being automatically backed up. Not good.
After chatting with iThemes Support (the people who make BackupBuddy), I learned that connectivity issues between the website and database can fool BackupBuddy into thinking there are no settings causing the plugin to revert to defaults. Connectivity issues could be due to DDoS attacks or a problem with the hardware. iThemes said they are aware of this issue and have built in more checks but as is life they can’t account for every single scenario.
Fortunately I caught the problem during a routine maintenance check on a client’s website. BackupBuddy now comes with a way to export the plugin settings so it’s a good idea to save a copy just in case.
