General

  • rsync is a software application and network protocol for Unix-like systems with ports to Windows that synchronizes files and directories from one location to another while minimizing data transfer by using delta encoding when appropriate. Quoting the official website: "rsync is a file transfer program for Unix systems. rsync uses the 'rsync algorithm' which provides a very fast method for bringing remote files into sync." An important feature of rsync not found in most similar programs/protocols is that the mirroring takes place with only one transmission in each direction. rsync can copy or display directory contents and copy files, optionally using compression and recursion.

-avh --inplace --no-whole-file
-a, --archive               archive mode; equals -rlptgoD (no -H,-A,-X)
-r, --recursive             recurse into directories

    --stats                 give some file-transfer stats

    --inplace               update destination files in-place, good for cow, implies partial
    --delete-after          receiver deletes after transfer, not during
-W, --whole-file            copy files whole (w/o delta-xfer algorithm)
-d, --dirs                  transfer directories without recursing
