Reliably Synchronize Drives and Directories

Safecopy synchronizes drives and directories, and carefully verifies the copy. When you are copying massive files or large directory trees, it's important to know that every file was copied accurately. Safecopy verifies byte-by-byte, or you can choose a quick metadata check.


Just and run it. The safeget-safecopy installer will download, verify, and install Safecopy. The safecopy command in ~/.local/bin. Depending on your system, you may need to add a link from a directory in your $PATH, such as /usr/local/bin.

How it Works

        safecopy SOURCE ... DESTINATION

It's just like the standard cp command. You can have as many source paths as you like. The destination path is always last.

Safecopy gives you a lot of control:

-h, --help         Show this help message
--verbose         Show progress
--quick         Only update files if the size or last modified time is different
--dryrun         Show what would be done, but don't do anything
--delete         Delete all files that are not in the source before copying any files
--nowarn         No warnings
--test         Run tests
--exclude EXCLUDE_PATH...         Exclude the files or directories (comma separated)
--verify         Verify copies
--persist         Continue on errors, except verify error
--retries RETRIES         How many times to retry a failed copy. Default is not to retry

If you need the rsync protocol run "pip3 install pyrsync2". But it's almost always better to replace rsync with safecopy and sshfs.

Error messages

Warning: setuid/setgid bit set on ...

    Safecopy detects when the setuid/setgid bit is set. This is almost always a serious security risk. To remove the bit:
                chmod -s PATH
