I have been looking at this and back to a how-to I was trying to follow.
For the case of backing up the localhost (c17-desktop) & trying to
exclude the /var/lib/backuppc directory where c17-desktop is the
BackupPC server...

I can not follow where to copy ssh keys to/from.  Does anybody have time
to baby step me thru this?  

When I do: "sudo su backuppc"
followed by: "ssh -x -l backuppc c17-desktop date"
i get: "ssh: connect to host c17-desktop port 22: Connection refused"
Which I believe ya'll are telling me is because I don't have ssh-keys
set up correctly.

I do have user backuppc set up to be able to run rsync w/o a password
via: "sudo visudo" 
which shows: 
# User privilege specification
root     ALL=(ALL) ALL
backuppc ALL=NOPASSWD: /user/bin/rsync

Thanx in advance, Skip
