Hard to say why this might have occurred. But, check your database retention policy. If you set it to a week…when the instance comes back online, it will apply the retention policy and remove the data.

I’m using the default autogen retention policy. I think that’s more that the database crash and the data are after this corrupt. I’m working currently on a backup system to keep the data save.
