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/ .

--------------------------

# rsync -crogpvltz -e ssh --exclude "bin" --exclude "ifany" --delete --delete-after --bwlimit 20 root@10.144.17.1:/apps/uae/ /apps/uae > /apps/uae/logs/sync.log

# rsync -avz -e ssh root@remotehost:/backup/reptest /backtmp/reptest/

# rsync -avz -e ssh /logstage/archive/DXBSEC/NODE0000/ db2inst1@10.20.202.236:/db2/archivelog/security/logstage/retrieve/DXBSEC/NODE0000/

# rsync -e ssh -avz --timeout=999 --delete --exclude dir-or-file-to-exclude --delete-excluded --stats -rlt user@remotehost:/home/lokams/

rsync useful options:
-------------------------

-a, --archive archive mode, equivalent to -rlptgoD
-n, --dry-run show what would have been transferred ( Preview mode )

-c - always checksum
-r - recursive into directories
-o - preserve owner
-g - preserve group
-p - preserve permissions
-t - preserve times
-v - verbose
-l - copy symlinks as symlinks
-z - compress file data
-P - show progress during transfer
-q - quite (decrease verbosity)
-e - specify the remote shell
-b - make backup
-R - Use relative path names
-u - skip files that are newer on the receiver

--stats give some file-transfer stats
--timeout=TIME set I/O timeout in seconds

--backup-dir - make backups into this directory
--bwlimit=KBPS - limit I/O bandwidth, KBytes per second
--delete - delete files that don't exist on the sending side
--delete-after - receiver deletes after transferring, not before
--daemon run as an rsync daemon
--address=ADDRESS bind to the specified address
--exclude=PATTERN exclude files matching PATTERN
--exclude-from=FILE exclude patterns listed in FILE
--include=PATTERN don't exclude files matching PATTERN
--include-from=FILE don't exclude patterns listed in FILE
--min-size=SIZE don't transfer any file smaller than SIZE
--max-size=SIZE don't transfer any file larger than SIZE

# --delete:
