rsync

rsync examples from command line.

To copy all the files in /home/lokams/* of remote host to local directory /backup/home/lokams/
# rsync -e ssh -avz –delete –exclude dir/* –delete-excluded –stats user@remotehost:/home/lokams/ /backup/home/lokams/

To copy the directory /home/lokams of remote host to local directory /backup/home. Directory “lokams” will get created in /backup/home.
# rsync -e ssh -avz –delete –exclude-from=~/.rsync/excludeFile –delete-excluded –stats user@remotehost:/home/lokams /backup/home/

To ignore the permissions errors while copying to remote windows/mac systems, use “-rlt” option.
# rsync -e ssh -avz –delete –exclude dir/* –delete-excluded –stats -rlt user@remotehost:/home/lokams/ /backup/home/lokams/

rsync behaves differently if the source directory has a trailing slash. Study and learn the difference between the following two commands before moving on. Use the -n option to rsync when testing to preview what would happen.

$ rsync -n -av /tmp .
$ rsync -n -av /tmp/ .
