Features and specs

What each product offers, as listed by its team.

RoboCopy 8 features
git-sizer 5 features
  • High Performance
    RoboCopy is designed for efficient and fast file copy operations, making it suitable for copying large volumes of data quickly.
  • Resumable Transfers
    It can resume file transfers after interruptions, reducing the need to restart the copy operation from scratch.
  • Advanced File Selection
    Supports complex file selection criteria, such as filtering by file size, attributes, and last modified date.
  • Mirroring Capabilities
    Can mirror entire directories, ensuring source and destination directories are kept in sync.
  • Logging and Reporting
    RoboCopy provides detailed logs and reports of copy operations, which is useful for auditing and troubleshooting.
  • Multi-threading
    Supports multi-threaded file copying, allowing parallel transfer of multiple files to improve performance.
  • Robust Error Handling
    Offers robust error handling and retry mechanisms, ensuring higher reliability in copy operations.
  • Access Control Compliance
    Preserves file and folder permissions (ACLs), ownership, and attributes, ensuring compliance with access control policies.

Possible disadvantages

  • Complex Syntax
    The command-line interface can be complex and intimidating for users who are not familiar with command-line operations.
  • No Native GUI
    RoboCopy does not include a graphical user interface (GUI), which may make it less accessible for some users.
  • Overhead for Small Files
    There can be considerable overhead when copying a large number of small files, which may reduce overall performance.
  • Limited Real-Time Monitoring
    Does not offer real-time monitoring or progress indicators in the way that some modern copying tools provide.
  • Potential Data Loss
    Incorrect usage of certain switches (e.g., /MIR) can result in unintended data loss, making it necessary to use caution.
  • Limited Support
    Being a native Windows tool, it primarily supports Windows environments and lacks the cross-platform capabilities of some alternatives.
  • Learning Curve
    It has a steep learning curve for advanced features, requiring users to invest time in understanding its full capabilities.
  • Comprehensive Repository Analysis
    git-sizer analyzes many different dimensions of a Git repository including commit count, tree size, blob size, history depth, and reference counts, providing a holistic view of repository health and potential scaling issues.
  • Easy to Use
    The tool is simple to run with minimal setup—just execute it within a git repository—and it produces clear, human-readable output that highlights potential problem areas without requiring complex configuration.
  • Identifies Performance Bottlenecks
    It helps identify specific issues that could degrade Git performance, such as excessively large blobs, deep history, large trees, or too many references, which is valuable before migrating or scaling repositories.
  • Open Source and Maintained by GitHub
    Being an official GitHub project, it benefits from credibility, community trust, and ongoing maintenance, and it is well documented with clear explanations of what each metric means.
  • Useful for Pre-Migration Checks
    It's particularly helpful for teams migrating repositories to new platforms or consolidating repos, as it flags potential issues that could cause problems during migration or with hosting providers' limits.

Possible disadvantages

  • No Automatic Remediation
    git-sizer only identifies and reports issues but does not offer any built-in tools or automated processes to fix problems like large blobs or excessive history depth—users must use separate tools like BFG Repo-Cleaner or git-filter-repo.
  • Output Can Be Overwhelming for Beginners
    While detailed, the output includes many metrics and threshold levels that may be confusing for users unfamiliar with Git internals, requiring some learning curve to fully interpret results.
  • Limited to Local Analysis
    The tool analyzes a local clone of the repository, so it requires users to have a full local copy of the repo (or at least enough history) to get accurate results, which can be time-consuming for very large repositories.
  • No Real-Time Monitoring
    It functions as a one-time analysis tool rather than providing continuous or real-time monitoring of repository health, requiring manual reruns to track changes over time.
  • Command-Line Only Interface
    The tool lacks a graphical user interface, which may be less accessible for users who prefer visual dashboards or are less comfortable with command-line tools.

  • Is ultracopier still the very best in terms of open source alternative file copying/merging tool ?
    I used robocopy on a slow network to transfer many gigabyte of data; properly configured with retries and everything worked great. Don't know about your merge needs, so take a look into it and do some tests before actually running it. Source: about 4 years ago
  • Is copying the best way to transfer large amounts of files?
    If you're copying a ton of files that vary in size, using a command prompt robocopy with the multi-thread parameter can make it so you are copying multiple files simultaneously and max out the bandwidth of whatever connection you're... Source: about 4 years ago
  • Game data to new PC
    This would probably work well. Oblivion mod managers edit load order by modifying dates on the files, and I'm not sure if dragging-and-dropping would keep that info. Source: about 4 years ago

  • how to keep github repos small?
    Also there’s a cool project from GitHub you can use to help understand the size of git’s objects in your git repo https://github.com/github/git-sizer. This might help you determine what the best cloning strategy could be. Source: almost 5 years ago
