We do everything we can to make sure data loss is impossible, but despite our best efforts, it may still happen.

Please make sure your files files are backed up if necessary before using rusync on sensitive data.

Thank you for your understanding!

• Easy to remember command line syntax.

• Print progress on one line, and erase it when done, thus avoiding flooding your terminal with useless noise.

• Displays a reliable ETA, without sacrificing speed.

• Unsurprising behavior: missing directories are created on the fly, files are only copied if:

  • destination is missing
  • destination exists but is older than the source
  • or source and destination have different sizes

Just two at the moment:

• --no-perms: preventsrusync from trying to preserve file permissions (useful if you copy data from a Linux partition to NTFS for instance).
• --err-list FILE: write name of entries that caused errors in the given file, separated by \n

I consider this project done - I don't intend on adding new features. The goal was to learn more about Rust and I've learned plenty of things already. If there's a feature present in rsync that is not available in rusync, just use rsync - or try and implement the feature yourself, I'll be happy to review and merge your changes :)
