When attempting to perform a database restore, there are a variety of errors that could occur. For example, the system may be unable to locate your back-file or the file validation could fail due to a syntax error in your .sql back-up file script.
To provide you visibility to these errors, so you can make any necessary changes to the back-up file before attempting the restore again, we record the details of the error in an error log within your _db_backups folder on the root level of your hosting account.
