When backing up an object not supported by the Bulk API, which other API should be utilized?

When backing up an object that is not supported by the Bulk API, utilizing the REST API is a suitable choice. The REST API is designed to enable direct access to Salesforce data in a straightforward manner, allowing developers to perform operations like retrieving, creating, updating, and deleting records.

In scenarios where the Bulk API cannot be used—typically with smaller datasets or for specific objects—the REST API is both efficient and easy to implement. It provides resources that can be accessed via standard HTTP requests, and its ability to work with JSON format makes it a preferred option for many developers, particularly for web applications.

Moreover, the REST API supports a variety of authentication methods and is well-suited for applications that require low-latency interactions or have a need to work with more complex queries. This makes it highly adaptable for backing up objects where the Bulk API falls short.

Selecting the REST API in this context ensures that users can effectively manage their data backups even in cases where other APIs might not be applicable.
