I agree, BackupPc does a good job, once installed and correctly configured, you 
can forget about it and simple let it do it's job.
:-)

IMHO, you have to break every backup scenario regardless of it is a virtualized 
or a real machine, into two pieces, Disaster Recovery (DR) and normal file- 
and/or databasebackup.
With BackupPc you "only" get a good filebackup solution.

While using LVM one could do snapshots in the sense of DR, and BackupPc with 
some additional scripts (dump databases, stop certain services etc.).
As others already posted in this thread, there a lot's of additional options, 
one could use to achieve the goal of a perfect backupsolution.

Perhaps, in question of DR also have a look at Rear 
http://rear.sourceforge.net/.
If money or perhaps "disposition" is no object, look at the commercial acronis 
backup&recovery solutions.
