Will MFT Pull Job Retrieve Incomplete Files via SFTP?

Summary

When performing a PULL action in OPSWAT MFT, the process may sometimes stop unexpectedly. This document explains whether MFT retrieves incomplete files during such transfers.

Use case

During an active MFT job, MFT first verifies and accumulates the file size before initiating the transfer process.

In this test, three file types were used:

• light_test
• medium_test
• heavy_test

Test File Execution

Example: A successful PULL action

• Job Logs: Show standard processing with no interruption
• Processing Status: Completed
• Final Status: Success

Issue – Scenario 1: Job Interrupted

In cases where the job is interrupted or disconnected unexpectedly during execution, the file transfer is aborted.

• Result: No files are received by MFT.
• Error Logs: Indicate termination or connection failure.

Issue – Scenario 2: File Still Being Written

When a file is still being written to (e.g., ongoing upload to SFTP), MFT detects it as incomplete or in use.

• Result: MFT will not retrieve the file. Only fully written, unmodified files are pulled.
• Job Logs: Reflect skipped or untransferred files.
