File System Task in SSIS with Real-Time Scenarios

The File System Task in SSIS is used to perform file and folder operations such as copying, moving, deleting, renaming, and setting file attributes. It is commonly used in ETL (Extract, Transform, Load) processes to manage files before or after data processing.

Real-Time Scenarios for File System Task

1. Moving Processed Files to an Archive Folder

Scenario: After extracting data from a CSV file, move it to an archive directory to avoid reprocessing.
Solution: Use the File System Task with Move operation.

Configuration:

• Operation: Move file

• Source Connection: C:\ETL\Source\sales_data.csv

• Destination Connection: C:\ETL\Archive\sales_data_20240501.csv

• Usage: After the Data Flow Task that processes the file.

---

2. Deleting Old Log Files

Scenario: Log files older than 30 days should be removed to save disk space.
Solution: Use a Script Task to identify old files + File System Task to delete them.

Configuration:

• Operation: Delete file

• Source Connection: C:\Logs\*.log (with a ForEach Loop to iterate files)

• Condition: Delete if LastModifiedDate < (Today - 30 days)

---

3. Copying a File Before Processing (Backup)

Scenario: Before processing a file, create a backup copy in case of failures.
Solution: Use File System Task to Copy the file.

Configuration:

• Operation: Copy file

• Source: \\Shared\Incoming\orders.xlsx

• Destination: \\Shared\Backup\orders_backup.xlsx

• Usage: Before the Data Flow Task that reads the file.

Answer:
You're trying to overwrite existing database abc with a backup of a different database or a backup from another server.  The default action is not to allow that to happen.

If you're sure you're doing the right thing, add the WITH REPLACE option to the RESTORE DATABASE command and it will proceed.  You may also need WITH MOVE options if the backup came from a database whose files were in different locations that the abc database.
