What is the checkpoint in SSIS?
We can configure a CHECKPOINT file in the SSIS package to log package execution information in it. If the package execution fails, SSIS uses the information in the checkpoint file to restart it from the point of failure. Once the package successfully executes, it removes the checkpoint file.
What is difference between checkpoint and breakpoint in SSIS?
A checkpoint is a restore point used in case the system fails and data has to be recovered. A breakpoint is used to analyze the values of variables before and after execution.

What are transactions in SSIS?
Two types of transactions are available in an SSIS package: Distributed Transaction Coordinator (DTC) Transactions: One or more transactions that require a DTC and can span connections, tasks, and packages.
For what data checkpoint data is not saved?
The checkpoint data is not saved for the For Loop Container and Foreach Loop container items. If a child container in the loop runs successfully, it is not recorded in the checkpoint file. So, when the package is restarted, the tasks in each of these container items are executed again.
What is the use of checkpoints in transactions?
What is a Checkpoint? The checkpoint is used to declare a point before which the DBMS was in the consistent state, and all transactions were committed. During transaction execution, such checkpoints are traced. After execution, transaction log files will be created.
What is the purpose of checkpoint?

If a transaction is started by a container, right-click the task or the container that you want to enroll in the transaction, and then click Properties. In the Properties window, set the TransactionOption property to Supported.
What is the use of checkpoints in SSIs?
Checkpoints in SSIS. Checkpoint configuration helps us to resume from the last task in the package. i.e., if the multiple tasks are there in a package. If there is any failure in any task it stores the fail task point in the checkpoint file once we restart the package the checkpoint helps to start from last point specified in checkpoint file.
What is the use of checkpoint in a package?
If there is any failure in any task it stores the fail task point in the checkpoint file once we restart the package the checkpoint helps to start from the last point specified in the checkpoint file. Once the package is succeeded it deletes the checkpoints.
How to log package execution information in SSIs?
We can configure a CHECKPOINT file in the SSIS package to log package execution information in it. If the package execution fails, SSIS uses the information in the checkpoint file to restart it from the point of failure.
How do I create a checkpoint file in SQL Server?
Take two execute SQL Tasks, one task with correct SQL command and the second task with improper command (so that it fails). Go to each task → properties → fail package on failure: true. Save checkpoint: true. Execute the package, as 2nd task is failed, the checkpoint file is generated.
