Sorry, I didn’t do any real investigation because it started working.
I am a lawyer, not a phone guy or a tech guy, who started with Trixbox almost 20 years ago and FreePBX is frankly so easy and reliable that I have no idea how it really works under the hood. (My eternal gratitude to you all for that, by the way)
That being said, I have daily, weekly and monthly backups configured to send backups to several network shares offsite. The share locations are set in the “filestore” configuration and they are automounted in fstab.
Backups are configured to email me (succeed or fail) when they run.
Normally, everything works like clockwork.
However, we recently had power problems that shut down the FreePBX machine. Upon rebooting it, I noticed after a few days that I wasn’t getting email notification of the backups.
So I logged into FreePBX and checked the backup settings. They all looked good. But no backups had been made since the date the power went out. So I did a “save and backup now” on my Daily backup and the backup went fine. Got the email, no problem.
Since I did that, all of the automatic backups have started working again (not just the Daily). Backups successful, emails sent.
This is not a big deal, practically speaking. But if it is just a matter of ticking the right box somewhere, I would like to fix it.
