All of a sudden yesterday evening, my users (there are only 2 besides me) reported that ALL the data in the main table (Rentals) of my application is GONE.  I have confirmed this as of yesterday evening that this data is no longer in the table.

 

No of my users deleted this data, so I do not understand how this data is just gone.

 

 I have logged a support case (1609460) yesterday, but I have not heard anything,

 

The application is http://creator.zoho.com/carlgifford/vacation-rental  and the form/table is Rentals.  There was OVER 4 years of data in this table and it was used to run our business.  I have a backup of the table exported hourly to Zoho reports; however, by the time I realized the issue the backup had run again and the data had been overwritten.

 

Has anyone else experienced this issue?  What could be the cause?  Were you ever able to get the data back?
