Whether following command line could work for me ?
On Terminal:
$ cd /
$ sudo tar -cvpzf backup.tar.gz --exclude=/backup.tar.gz --one-file-system /dev/sda
Any precaution I need to pay attention ?
Please advise. Thanks

You should use fsarchiver for that purpose.. I thing using tar you might lose things.. or get an inconsistent or broken restored system, im not sure you can preserver all atributes , timestamps, symlinks, etc by using tar- fsarchiver is safer to use, you wont get any trouble when restoring system backup
FSArchiver . Unlike tar/dar, FSArchiver also creates the file-system when it extracts the data to partitions. Everything is checksummed in the archive in order to protect the data. If the archive is corrupt, you just loose the current file, not the whole archive.
The purpose is to provide a safe and flexible file-system backup/deployment tool.
FSArchiver t will preserve all the standard file attributes (permissions, timestamps, symbolic-links, hard-links, extended-attributes, …), as long as the kernel has support for it enabled. It allows to preserve all the windows file attributes (ACL, standard attributes, …). It can be used with LVM snapshots in order to make consistent backups of all filesystems including the root filesystem.
