Usage:

rsync -avhuz /path/to/src_folder/   [email protected]:/home/username/path/to/dest_folder/
alias rsyncBackupCompareAttr='rsync -avhuz --progress --delete --log-file=rsyncBackupLog.txt'
alias rsyncBackupIgnoreAttr='rsync -avhuz --no-perms --no-owner --no-group --progress --delete --log-file=rsyncBackupLog.txt'

OBS:
rsync folderA folderB will cp folderA into,under folderB.
rsync folderA/ folderB/ will cp folderA's content into folderB.
Thus, /s after both folderX are mandatory.
Becareful with -u: it will ignore the dest file with newer timestamp.
