Abstract: A data storage system, according to certain aspects, automatically determines the accuracy of replication data when performing data backup operations. For instance, the system performs data backup using replication data rather than source data to reduce the processing load on the source system. The backup data is then associated with the source data as if the backup had been performed on the source data. If the replication system fails, then backing up replication data results in backup data that does not accurately reflect the source data. The system automatically determines the accuracy of replication data during data backup.

Abstract: The data storage system according to certain aspects can implement table level database restore. Table level database restore may refer to restoring a database table and its related data without restoring the entire database. The data storage system may use table metadata index to implement table level restore. A table metadata index may be created for each table, e.g., during a backup of the database. The table metadata index for a table can include any type of information for restoring the table and its related data. Some examples of the type of information included in the table metadata index include the following: container for the table, table backup location, system data, table index, table relationships, etc. Table metadata index can make the restoring of tables fast and efficient by packaging information that can be used to restore a table and its related data in an easily accessible manner.
