Error message when starting Kodi

I am virtually a new Android/Kodi user with very little experience or knowledge in this area. I purchased an MXIII-G Android 5.1.1 API level 22 (kernel:linux 3.10.33) Git:2016-02-20-a5f3a99 from BG (Banggood.com). It came with Kodi Jarvis 16.0. I have been using it since September-October.

Every time I start Kodi, I get a message “backup error check the log for more information”. Other than that, it seems to be working fine. Should I be concerned about this? Is there a way to eliminate this recurring message?

I hope someone can help me with this. Appreciate your patience and support.
