OnSite won't backup since November 13, 2018
I've got a few locations and at least one is running Lightspeed 2016 188.8.131.52 (r13) which is obviously old but I don't need any new features and it works great for what I need it to do. However, for some reason, it won't backup. Last backup shown in Users>Shared>LightSpeed>Backups is November 13, 2018 with consistent backups before then.
There were no hardware changes then and the Mac was and is still running OS 10.11.6 since I have no need to upgrade and have aps all of a sudden stop working.
When logging in to use LightSpeed, it gives the warning that it is unable to verify that any automated backups have completed in the last 7 days and to check the backup schedule.
If I go into Tools>Utilities>Backup Database, I get "Lightspeed could not communicate with the backup server due to a configuration error."
If you go into System Preferences and the LightSpeed Server preference pane - and the server is running - and then I click on the Backup "tab", I immediately get a "Communication to the Lightspeed server daemon failed" message. (Unlocking to make changes does not help BTW)
I don't know if this is related but if I look in Console, I see this occasionally "4/24/19 2:23:34.675 PM Lightspeed Server Manager Helper: BUG in libdispatch client: kevent[EVFILT_WRITE] delete: "Bad file descriptor" - 0x9"
This has been going on for months and I'd like to backup. Any ideas? Huge thanks in advance.
