All data in the database is gone after an alert

[Hadeel]

Hi !
In my environment I had my LM running for over 3 years. 
Yesterday, for the first time all data in the database was gone and all objects and scripts are lost.
I can see alert log but there is no other log or error log.
Have you ever experienced this ? How can I avoid it from happening?

Most likely a problem with the microSD card in LM. Run this script once and post what you get in Logs tab:

Code:

files = io.ls('/data/dbfail/')
log(files)

Thank you for looking into the inquiry!
This is what I got after executing the code.
