Why Is Data Missing from My Database?

DDS does not delete or perform any operations on any user data. If this problem occurs, check whether a misoperation has been performed. Restore the data using backup files, if necessary.

Solution:

• Use the DDS restoration function to restore data. For details, see chapter "Backup and Restore" in the Document Database Service User Guide.
• Import backups to DDS. For details, see section Migrating Data.
