copy

What This Skill Does

The OpenClaw 'copy' skill serves as a comprehensive toolkit for managing data duplication, synchronization, and storage optimization. It abstracts complex CLI operations like rsync, reflink-based Copy-on-Write (CoW), and incremental mirroring into accessible commands. Designed for developers and system administrators, this skill simplifies the maintenance of complex directory structures, ensures data integrity during transfers, and provides deep insights into file system behaviors across different operating systems. Whether you are performing high-speed local backups, configuring differential syncs, or managing large datasets with I/O-intensive requirements, the 'copy' skill offers the necessary logic to execute these tasks safely and efficiently.

Installation

To integrate this skill into your OpenClaw environment, execute the following command in your terminal:

clawhub install openclaw/skills/skills/bytesagain1/copy

Ensure your system has the necessary permissions to read and write to your desired target directories. Configuration of the COPY_DIR variable can be done in your profile settings to define where the skill stores its local metadata.

Use Cases

• Incremental Backups: Utilize rsync patterns to mirror production directories to external storage, ensuring only changed data blocks are transferred to save time and bandwidth.
• Storage Optimization: Use Copy-on-Write (CoW) features to duplicate large virtual machine images or container layers instantly without consuming additional physical disk space.
• Data Migration: Execute batch migrations while applying complex filters (e.g., excluding '.log' files or matching specific date ranges) to clean up datasets during the move.
• Verification: Employ the pre-copy and post-copy checklist features to guarantee checksum integrity between source and destination files.

Example Prompts

1. "OpenClaw, use the copy skill to rsync my /projects directory to the remote server, excluding all node_modules folders."
2. "I need to duplicate this 50GB dataset. Can you check if my filesystem supports CoW and perform a reflink copy?"
3. "Run the post-copy verification checklist on my recent migration to ensure no files were corrupted during the transfer."

Tips & Limitations

Always run the checklist command before and after mission-critical transfers to ensure data consistency. While the skill supports parallel execution, be mindful of your system's I/O limits, as heavy parallel operations can saturate disk throughput. Note that Copy-on-Write functionality requires underlying filesystem support (e.g., Btrfs, ZFS, or APFS); if your filesystem does not support reflinks, the skill will gracefully fall back to standard copy operations. Exercise caution when using aggressive include/exclude filters to avoid accidental data loss or skipped files in sensitive directories.
