[rdiff-backup-users] rdiff-backup over a simple copy

[Christof Damian]

hello,
I am new to rdiff-backup and I have the following question: for some
machines I want to backup I already have backups of all the
files, either on tape or a simple copy. Can I use this as a starting
point for a rdiff-backup, so I won't have to copy everything again? 

Or would be the best solution to do something like this:

  rdiff-backup theoldbackup newbackup
  rdiff-backup remotemachine::/ newbackup 

thanks for any help,
christof
