rsync command to backup home tree to another disk

view story

http://unix.stackexchange.com – I just like to make sure I am using the correct rsync command on Linux. I did not want to run and end up losing data as I am new to Linux and I have no backup now. I am on Linux mint, and I have /home/nasser/ and I want to back up everything BELOW it, to /home/BACKUP/ where I have a backup disk mounted. Therefore, I'd like to end up: /home/nasser/file1 /home/nasser/file2 /home/nasser/A/file1 to /home/BACKUP/file1 /home/BACKUP/file2 /home/BACKUP/A/file1 including ofcourse all hidden files and everything. Exact copy. I made sure that /home/BACKUP/ is owned by me (user and group). (I ju (HowTos)
