Automated data backup

One or more computer-readable storage media encoded with instructions that, when executed by one or more computers, cause the one or more computers to perform, as part of a data backup process for a plurality of data objects, operations comprising:

• receiving, from data storage, a schema that indicates relationships between different types of data objects in the plurality of data objects and is separate data from the plurality of data objects:
• determining, for each of two or more data objects from the plurality of data objects and using metadata for a respective data object that includes at least one or more relationships from the received schema, a backup score that indicates an importance of the respective data object;
• determining different priority levels for two or more subsets of the plurality of data objects based at least in part on the backup scores;
• and
• backing up at least one of the subsets of the plurality of data objects according to the respective priorities of the subsets.
