CopyQueue Tutorial: Fast, Reliable File Syncs
What CopyQueue is
CopyQueue is a tool for queuing and performing file copy/sync operations reliably across folders, drives, or network locations. It processes operations in order, retries on transient errors, and can resume interrupted transfers.
Key features
- Queued operations: Add multiple copy/move jobs that run sequentially to avoid I/O contention.
- Resumable transfers: Partial copies pick up where they left off after interruptions.
- Retry logic: Automatic retries for transient failures (network glitches, locked files).
- Filters & rules: Include/exclude files by name, size, date, or pattern.
- Integrity checks: Optional checksums (e.g., MD5/SHA1) to verify successful copies.
- Bandwidth/throttle control: Limit transfer speed to avoid saturating networks.
- Logging & reporting: Detailed logs with per-file status and error messages.
- Scheduling & automation: Run jobs on a schedule or trigger on file events.
Typical workflow (step-by-step)
- Create a job: Specify source and destination paths.
- Set options: Choose copy vs move, enable checksum verification, set retry count, and configure filters.
- Queue files: Add multiple jobs or entire directories to the queue.
- Start processing: The queue runs jobs sequentially (or with configurable concurrency).
- Monitor progress: View per-file progress, ETA, and transfer rates.
- Handle errors: Review logs for failures; failed items can be retried or skipped.
- Verify results: Use integrity checks or compare file lists to confirm success.
Example command-line usage (generic)
bash
copyqueue add –src ”/path/to/source” –dst ”/path/to/dest” –verify sha1 –retries 3 copyqueue start copyqueue status copyqueue retry-failed
Best practices
- Use checksums for critical data to ensure integrity.
- Limit concurrency on systems with slow disks to reduce thrashing.
- Schedule large jobs during off-peak hours to minimize impact.
- Test filters on a small subset before running large syncs.
- Keep logs for audit and troubleshooting.
Common troubleshooting
- Permission errors: Ensure the user has read access to source and write access to destination.
- Locked files: Use retries and, if needed, schedule when files are not in use.
- Network timeouts: Increase retry counts and network timeouts; enable throttling.
- Checksum mismatches: Re-copy affected files and check disk/network health.
