Transfer Operations

oMFT's primary function is to manage file transfers between different storage systems. This page explains the transfer operations available in oMFT and how to configure them.

Transfer Types​

oMFT supports several types of transfer operations, each with different behaviors:

Copy​

The Copy operation copies files from the source to the destination. Files are only copied if they don't exist at the destination or if they've been modified at the source.

Source → Destination

Sync​

The Sync operation makes the destination identical to the source, adding, removing, and updating files as necessary.

Source → Destination (with deletions)

Move​

The Move operation copies files from the source to the destination and then deletes the source files after a successful transfer.

Source → Destination → Delete Source

Bidirectional Sync​

The Bidirectional Sync operation synchronizes files in both directions, ensuring that the newest version of each file is present in both locations.

Source ⟷ Destination

Transfer Configuration​

When creating a transfer in oMFT, you need to configure the following elements:

Basic Configuration​

  • Name: A descriptive name for the transfer
  • Description: Optional details about the transfer's purpose
  • Source: The source connection and path
  • Destination: The destination connection and path
  • Transfer Type: Copy, Sync, Move, or Bidirectional Sync

Advanced Options​

File Selection​

  • Include Patterns: Patterns for files to include (e.g., *.txt, data/**/*.csv)
  • Exclude Patterns: Patterns for files to exclude (e.g., *.tmp, **/._*)
  • Min Size: Minimum file size to transfer
  • Max Size: Maximum file size to transfer
  • Min Age: Only transfer files older than this
  • Max Age: Only transfer files newer than this

Transfer Behavior​

  • Checksum: Compare files using checksums instead of size/date
  • Delete Before: Delete destination files before transferring
  • Delete During: Delete destination files during transfer
  • Delete After: Delete destination files not in source after transfer
  • Update Existing: Update existing files at destination
  • Skip New: Skip new files not present at destination
  • Skip Newer: Skip files that are newer at the destination

Performance Options​

  • Transfers: Number of concurrent file transfers
  • Checkers: Number of concurrent file checkers
  • Bandwidth Limit: Maximum bandwidth to use in bytes/s
  • Buffer Size: Size of transfer buffer (default: 16MB)
  • Chunk Size: Upload chunk size for chunked uploads

Transfer Execution​

Manual Execution​

Transfers can be run on-demand:

  1. Navigate to the Scheduled Jobs section
  2. Find your job in the list
  3. Click Run Now
  4. Monitor the job progress in real-time

Scheduled Execution​

Transfers can be scheduled to run automatically:

  1. Navigate to the Scheduled Jobs section
  2. Create a new schedule linked to your transfer configuration
  3. Set up the schedule using cron syntax or the schedule builder
  4. The transfer will run automatically according to the schedule

Transfer Monitoring​

Status Indicators​

  • Pending: Transfer is waiting to start
  • Running: Transfer is in progress
  • Completed: Transfer finished successfully
  • Failed: Transfer encountered an error
  • Canceled: Transfer was manually canceled

Transfer Details​

For each transfer execution, oMFT records:

  • Start and end times
  • Duration
  • Number of files transferred
  • Total bytes transferred
  • Files skipped
  • Errors encountered
  • Detailed logs

Transfer Logs​

oMFT provides detailed logs for each transfer:

  1. Navigate to Transfer History
  2. Click on a View Details button on the transfer entry

The logs include information about:

  • Each file transferred
  • Skipped files
  • Errors
  • Performance metrics
  • Overall transfer summary

Troubleshooting Failed Transfers​

When a transfer fails, oMFT provides information to help identify the cause:

  1. Check the error message in the transfer history
  2. Review the detailed logs for the specific error
  3. Common issues include:
    • Permission problems
    • Network connectivity
    • Invalid credentials
    • Path not found
    • Disk space issues

Best Practices​

  • Use meaningful names for your transfers to easily identify them
  • Start small when testing new configurations
  • Use include/exclude patterns to limit scope when working with large directories
  • Set appropriate concurrency based on network conditions and system resources
  • Use checksumming for critical data to ensure integrity
  • Set bandwidth limits to avoid network congestion during peak hours
  • Schedule large transfers during off-peak times
  • Use notifications to stay informed about transfer results
  • Regularly review logs to identify potential issues
