suggestions to sync partitions

[Albert Martin S]

Hello Ubuntu  experts and users
I am preparing my backup / restore strategy and would like to 
hear your suggestions how to get an comfortable/easy/fast way to 
have 2 partitons, i.e. original HOME and its backup on an USB HDD
sync'ed !

Is "rsync" a (good) solution too do or are you having other
recommendations ?

The best would be a script to have it sync'ed every time before shutdown
automatically 
or called when needed !?

Glad to hear and learn from you. :-)

TIA and cheers, svobi
