Periodically my saved channel groups disappear and I'm left with just the standard channel groups.  Normally I just recreate the groups but I'm wondering, is there is a way to prevent this?  
Is this a Kodi problem or a Tvheadend problem? 
Can they be backed up?  
This most recently happened on my CoreELEC box but I've also had it happen on my Shield TV

How do you create the groups? With the tvheadend web UI or with Kodis channel group manager?

Kodi's channel group manager.

Does this happen after you 'clear data' in settings-pvr livetv-general ?

Manually created groups in kodi will be gone after doing this. If the backend provides the groups they will be reloaded from it in kodi.

Just tried with a backend with, and one without providing channels groups. My manual groups are gone.

I don't remember doing a "clear data" the last time it happened.  However, the CoreELEC box had locked up and I had to do a manual power cycle.

Deactivate sync groups with backend in Kodi PVR settings. Look at the help text for explanation why this solves your problem.

Thanks, I'll give that a try.

I could go months without having a problem so it's too early to tell for sure.  But since syncing channels to backend was enabled it seems this was likely the problem.  
Thanks
