Extracting Multi-Part Data Exports

Prev Next

This guide provides step-by-step instructions on consolidating and extracting multi-part exported files provided by Rocket.Chat Cloud.

  1. Ensure you have all the .tar.gz.part files downloaded to the same directory.

  2. Use a Unix-based system (Linux, macOS, or Windows Subsystem for Linux) with standard tools like Bash, tar, and gzip installed.

  1. Verify Checksums (Optional but Recommended):

    Compare the provided checksum file with your downloaded parts using:

sha256sum files.tar.gz.part*
Bash

Ensure all parts are intact before proceeding.

  1. Merge File Parts:

    Run the following command to combine all parts into a single .tgz file:

    for i in {1..N}; do cat files.tar.gz.part$i >> consolidated.tgz; done
    Bash

    Replace N with the total number of parts you received.

  2. Extract the Consolidated File:

    Extract the .tgz file using:

    tar zxvf consolidated.tgz
    Bash

  3. Troubleshooting Extraction Errors:

    If you encounter errors, first check the integrity of the archive using:

    tar zxvf consolidated.tgz
    Bash

    If the issue persists, verify the integrity of the consolidated file:

    bashCopy codegzip -t consolidated.tgz
    Bash

  1. Checksum Mismatch: Re-download the affected parts and verify checksums again.

  2. Extraction Fails:

    • Ensure sufficient disk space is available (at least twice the size of the exported data).

    • Use the --ignore-zeros (-i) flag if encountering EOF errors.

  3. Missing Tools: Install the required tools using your system's package manager (e.g., apt, brew, or yum).

Always use the commands provided above to ensure compatibility with exported Rocket.Chat data.
