Backup and restore onto different hard drive

[Sridhar Dhanapalan]

-a does an 'archive' copy, meaning that it tries to preserve as much
as it can (permissions, etc.).

If you choose this option, don't use it to copy a live system.

I still think that something like clonezilla is a better alternative.
You preserve the entire filesystem and all its metadata, and you can
trivially resize afterwards it to match the target disc with gparted.
