I’m looking for a linux program that can mirror a directory to another drive and move a subdirectory in the mirror.

    lsyncd does just this. It’s intended use is to sync directories between systems over slow(ish) uplink, but it can work locally as well. It takes some fiddling to set up, but once set up it just does it’s thing seamlessly at the background. However if you’re just looking for a backup solution I’d might look for something else, like a plain rsync script.

      This is the best answer. I use it regularly to keep hundreds of TB in sync across nodes. Works extremely well and is pretty much hands off once setup.

    Why not exclude the folder you want to move from the initial sync, and sync that folder separately to the final location?

      I am trying to create a crontab to backup multiple directory in which files change their location, but I don’t know if links would solve it

        You can also have rsync exclude specific files, so you could sync the main dir first, then the special subdir specifically

    I use RealTimeSync.

    It just… Works. I love it. It’s free.

    There are plenty of features that could effectively let you do what you want.

    Mine is set to sync my server with a backup whenever my main PC is idle for 20 mins. Once it determines how to sync, it lets me review before syncing.

    Restic, kopia, and Borg are all pretty good backup tools with deduplication built in, so they might be a good option if you’re doing this for backup purposes?

    As long as the backup system performs deduplication, it should be able to store the backup data efficiently even if the source files are constantly moved around or renamed.

    ZFS snapshots can perform deduplication. There is also ZBackup, which also has deduplication support.

    rclone sync might be a acceptable?

    It doesn’t move files from one dir to another but it would delete the old directory and recopy to the new directory.

    I think rsync has the same functionality but could be wrong
