Yes, but you have to test a restore of a typically-sized archive before 
deciding that this method is suitable for your purpose. While it may 
take a few hours or less to make the tar copy, it will likely take at 
least a few days to restore a usable disk copy will all the hardlinks.

On the other hand, if your external disk has as much space as the live 
partition, you can stop backuppc, unmount the partition, and image-copy 
to a matching partition on the external drive and have a copy that is 
directly usable.
