I have a large number of FPBX systems versions 14 -16. I have them all doing a local backup every so often. Many of them every week. I have a script that I run from cron to move the files to a S3 server. In checking in on the backups there are a fair number of systems that do not appear to run. My script emails me if there is a failure. I get no emails. There are no logs that I can find to show if the backup run. Is the backup routine a hit and miss type of thing?
You need to provide more details than what you have. Do the backups exist? Are there any indicators in log files? How is a system configured that doesn’t work? Is it all of the systems, if not what are the details about the systems not working.
