# To copy files from remote to local, maintaining file properties and sym-links
# (-a), zipping for faster transfer (-z), verbose (-v):
rsync -avz host:file1 :file1 /dest/
rsync -avz /source host:/dest

# To copy files using checksum (-c) rather than time to detect if the file has
# changed. (Useful for validating backups):
rsync -avc <src> <dest>

# To copy /src/foo folder into destination:
# This command will create /dest/foo if it does not already exist
rsync -auv /src/foo /dest

# To copy contents of /src/foo into destination:
# This command will not create /foo_bak/foo folder
rsync -auv /src/foo/ /foo_bak

# To copy file from local to remote over ssh with non standard port 1234 to
# destination folder in remoteuser's home directory:
rsync -avz -e "ssh -p1234" <source> <username>@<host>:<dest>

# Use the specified authentication key, instead of typing a password:
# (The key can be generated by ssh-keygen, and the public key should be placed
# in remote's authorized_keys, e.g. using ssh-copy-id)
rsync -avz -e "ssh -i ~/.ssh/id_rsa" <src> <dest>

# Log into remote as a user, but promote to root, to access privileged files:
rsync -avz --rsync-path="sudo rsync" user@<src> <dest>

# Rsync only symlinks and preserve them as symlinks (dont follow them):
find /path/to/files -type l -print | \
  rsync -av --files-from=- /path/to/files user@targethost:/dest_path

 tldr:rsync 
# rsync
# Transfer files either to or from a remote host (but not between two remote hosts).
# Can transfer single files or multiple files matching a pattern.
# More information: <https://manned.org/rsync>.

# Transfer a file from local to a remote host:
rsync path/to/local_file remote_host:path/to/remote_directory

# Transfer a file from a remote host to local:
rsync remote_host:path/to/remote_file path/to/local_directory

# Transfer a file in [a]rchive (to preserve attributes) and compressed ([z]ipped) mode displaying [v]erbose and [h]uman-readable [P]rogress:
rsync -azvhP path/to/local_file remote_host:path/to/remote_directory

# Transfer a directory and all its contents from a remote host to local:
rsync -r remote_host:path/to/remote_directory path/to/local_directory

# Transfer directory contents (but not the directory itself) from a remote host to local:
rsync -r remote_host:path/to/remote_directory/ path/to/local_directory

# Transfer a directory [r]ecursively, in [a]rchive (to preserve attributes), resolving contained sym[L]inks, and ignoring already transferred files [u]nless newer:
rsync -rauL remote_host:path/to/remote_directory path/to/local_directory

# Transfer a file over SSH and delete remote files that do not exist locally:
rsync -e ssh --delete remote_host:path/to/remote_file path/to/local_file

# Transfer a file over SSH using a different port than the default and show global progress:
rsync -e 'ssh -p port' --info=progress2 remote_host:path/to/remote_file path/to/local_file
