To maintain governor limits on the number of batches per rolling 24-hour period in your backup solution, which API is suitable?

In Salesforce, maintaining governor limits is critical for the efficient execution of operations, particularly when dealing with large volumes of data. Among the available APIs, the Bulk API stands out as the most suitable option for batch processing in Salesforce, especially when aiming to adhere to governor limits.

The Bulk API is designed specifically for handling large data sets by processing records in batches, making it ideal for backup solutions that must operate within the constraints of Salesforce's governor limits. It allows for the transfer of up to 10,000 records in a single call and is optimized for loading or deleting large numbers of records asynchronously, which is especially beneficial for backup operations where data integrity and efficiency are essential.

In contrast, the SOAP and REST APIs are more suited for real-time interactions and may have stricter limits on the number of transactions one can perform in a given time frame. The SOAP API, while allowing for operations on Salesforce data, is traditionally synchronous and not optimized for bulk operations. Similarly, the REST API is primarily designed for lightweight and flexible interaction with Salesforce data and is not specifically tailored for batch processes in large volumes.

The Streaming API is intended for receiving real-time notifications of changes to Salesforce data, focusing on event-driven architectures, and is not designed for executing batch processes.
